First of all great video, kept simple and very well explained. many tips there. Was quiet surprised to see the number of viewers and subscribers of this channel, then I noticed the date of the Channel is like a month ago. Great job dude and wish to see many more. Cheers !
Didn't see you flush the heater core in this video which is super easy and should be done. Also after the garden hose flush you will still have some tap water in the system. What I do after flushing is blow compressed air through the heater core to get most of the tap water out of there. Then fill the entire system with distilled water, run the engine up to operating temp, then drain all that out. Again blowing air through the heater core. You will be surprised how much more dirt comes out... Then you can refill with on gallon concentrated antifreeze/coolant and one gallon distilled water then top off the remaining with a 50/50 mix. Also you mentioned running only water (distilled) in the summer time for better cooling. While you can do this, it is not recommended because the antifreeze/coolant has lubricants for the water pump.
The OEM Thermostat is a 195 degree. I do run the 180 myself to help with cooling in the summer, but if you look at the specs, stock is 195. Just want to clarify as you said that OEM is 180. Also if you have cold weather climate, you may not get quite enough heat from your heater by running a lower thermostat
Agreed. I ran into this with mine and took the aftermarket 180 out. it would never reach operating temp and the heater wouldn’t provide hot air. Living in Dallas with the summer heat and traffic I haven’t ran into any overheating issues.
@@altellan same here, I live in the mountains of San Diego where we get snow. The previous owner used the 180 and the heater couldn’t get to operating temp so I put a 195 in
I live in PA where it's freezing I have very lil heat my heater core hoses are perfect ,changed the water pump , thermostat housing, and put in a new 195 thermostat and still my heat is mediocre. Think I should try a 180? I tested it with the scanner and the hottest it has ever gotten was 202 then dropped right back to 184
Yup 195 is stock and I still run it. Quick question, any ecu issues with the 180 t-stat? I'm under the impression that the ecu will adjust the fuel/air ratio with regards with engine temp. Do you notice your xj running rich or lean because of the colder t-stat? Any change in mpg?
Great video. My cherokee has been sitting for a year or two and im welding up the unibody rn and a new floor pan. Checked the radiator cap and theres like gunked up orange sand. No fluids. Ugh. This was easy enough tho thanks to your video. Thank you. Beautiful xj too! Mine needs some lovin and its finally time to get her running again.
Lol... it is a beast of a winch. I agree, it definitely restricts some of the air flow. However, with an oversized radiator, larger Tstat casing assembly and a new water pump.... I am able to have my cake and eat it too! Thanks so much for watching!
Nice video Jeremy and super nice looking Jeep... We have a 1991 Jeep XJ Sport and I want to flush it out. Hoping all the steps will be the same. Your engine compartments looks the same as ours as far as I can tell. BTW: I've been looking for another XJ model with nice paint and no rot/rust here in NJ, but so far not having too much luck. We're keeping the 1991, we just wanted to get another as we like them so much!...Thanks. Phil Jersey Shore Area
Thank you so much for this I have a 1998 Jeep kind of like yours I love my Jeep but this is going to help more to take care of my baby thank you so much appreciate it😊👍🙂
I know it's an old video but I'm on my second XJ. I had one when I was 16 and I'm now 29 and really wanted another. I got an 01 Solar Yellow and there's 'mud' under my cap. All test indicate not a head gasket, just a filthy system. This video is VERY informative and I thank you for it. Gonna be doing it this weekend, step by step. Hopefully how to wire a fan to a switch aswell if I can find a video. Would like to be able to manually turn it on.
If your radiator and coolant resorvoir has brown mud that is rust. You must have used water. Immediately flush the system with water. Just replace the water 2 to 3 times over a couple of days. Then once the system is clean replace it with coolant.
On my first at 16 was my dads but got the cats stolen nd asked if I could keep her nd just about start her over so I’m tryin to feed myself with as much knowledge in the system as possible
If you have a 4.0l do not just add water your going to get rust. Iron blocks do not like water. Rust will kill your radiator and make it not cool your engine off properly
I did everything you said but when it came to adding the 1.5 gallons of coolant and 1.5 of water my jeep only took 1 gallon of each before being full and not letting us add any more. Any insight to why this could be the case would be helpful. It's a 1993 cherokee, 4.0L inline 6.
An old trick to clean/flush a radiator is to use automatic dishwasher fluid or gel for flushing. Add about one ounce per gallon into your radiator after flushing out the anti freeze. Drive it around for a few hours and then flush out all the detergent. Add antifreeze and distilled water according to the temperatures in your area.
Please do not forget to flush the heater core. Put the heating on max to open the core first. Another tip. In the block underneath the manifold there is a coulant drain plug. Use a square 8mm to open this plug. About a gallon of coulant comes out 😀

Thank you again and I appreciate the comment. I actually have replaced my sensor for the rough idle. I should do a short bud on it though. Thanks for watching and I am happy you enjoy them. Many more to come!
Just have to be careful and watch the fluid level. If you keep the engine running when filling up, it will burp itself and level the fluid out. Of course, too much fluid and it will overflow. Just have to add a little at a time.
what kind of mods do you have to your XJ? i plan on buying one soon (i’m not sure it’s an XJ) but i’m interested in adding after-market mods to my jeep
Hello everyone! I am happy that you all are liking my videos. I will be posting the PART 2 of the motor build this next week. If you have a specific request that you would like me to do a video on, please let me know.
It's easier to use the Prestone flush kit that goes on the heater hose into the tstat housing and run the engine with the setting on defrost....everything is flushed out the radiator cap fill spout.
I worked at a dealership for years, the best flush is the starbright marine grade descaler, I use it every 36 months, and I'm always shocked at the crap it removes from my cooling system, FYI, my engine never gets hotter than spec.
Yes. Once you have burped the system properly, top it off to full and it will be complete. If the coolant gets low during operation or over time, just add coolant. No need to burp the system unless you are draining the entire coolant. Thanks for watching and appreciate the comment.
Great how to on doing a coolant flush . That Dexcool garbage smells like urine if you ask me . We have had a few GM vehicles in the past and one of the first things I did was completely flush the system , change the thermostat and put in green antifreeze at a 50 /50 mix and low and behold the smell went away . Where did you get your antifreeze at if you don't mind me asking ? I am tearing my TJ down starting next spring and when it goes back together I would like to try that antifreeze your using . Take care and be safe and looking forward to more of your videos.
Thank you very much! I appreciate you watching. I agree, the Dex coolant puts off a awful smell. It’s deceiving as it smells like the coolant is burning but it’s not. I purchase the Race Pro Anti from Advanced Auto Parts. It’s pretty much all I use. Let me know if you have any other questions. My next video will be up soon and it will be how to install the custom gas tank skid plate. Thanks again for the view!
Thank you for letting me know where to get the antifreeze at. There is a Advanced Auto Parts in our area on Washington Street. Looking forward to your Gas tank skid video. Take care and be safe.
We have very high temp during the 65% of the year, in Mexico border ,my XJ 2000 never receive a good maintenance during my last 5 years of use ,the cherokee the last year support during 3 hours running trap in high traffic without moving, 5:30pm at 38-39 C , this event and others histories make me see with proud this warrior, after that invest on it to take more care , i dont use A/C in my personal vehicles, but the truck have mounted the system, i decide remove the ac radiator , and runs very vey fine reduce easy the heat more than 1/8 of temp. An under the capo,and have a good fast capacity to cooling when running, the old radiator was dirty and reduce the capacity to refresh ,actually the activation of the electric fan was reduced,🫡💪🏻👍🏼😎 of course you need to be crazy ,to leave the A/C but is not imposible. God bless you .
@@jameswiththejeep2562 to flush mine I remove the lower hose so it drains the radiator AND block. Not really a flush but totally drains the block. I did that, drove it a few miles then did it again.
Where did you get that front emblem? I have a 2000 classic and all the emblems were crusty so I replaced them with black emblems. Is it from a different model? I’m having a tough time finding one that will fit the curve of the front
Nice video. The only critique I would say is that anti-freeze is also anti-boil. It increases the boiling point of regular water. it also changes it's flow rate so that it does not cavitate inside the water pump. Regular water is not the best, 50/50 is the best. Water will get you home.
How ABOUT THE WATERT RESERVOIR? Beside there is a special out let for the flush, there is a flush hole on the side, we live in the south so I removed the thermostat period.
I am going insane my jeep stays on for 5 mins and it doesn’t sit in the funnel it shoots out like a volcano so I have to turn it off!! Not sure what’s going on
Can I fill the system with straight distilled water even if I have coolant in the block? I just replaced the water pump but there is still some green coolant sitting in the engine
Yes, you can fill the system with straight distilled water if that is your only source. I would highly recommend that you use a good antifreeze as to protect the engine and the coolant system with the proper elements included with antifreeze. Distilled water is a great source for your system if you have no other choice. It is not a good long term method but does work. Distilled water does not have the coolant protectants needed for your engine and the proper lubrication that benefits the cooling system. However, distilled water is a good substitute for a temporary addaditive.
Ok if i am in Middle Eastern country where temp in summer can go to 125F the coldest days only 75f. What would be an acceptable thermostat? I found in local parts store a 160 thermostat.
I know this is old, and you probably figured it out. But some water will come back out, but if all of it is, that's because your thermostat is closed completely, and you're gonna have to take it off. That's what I had to do, and it made a big difference, not just on the water flowing through but on how much of that old dirty coolant got washed out.
Thank you for watching! Pending on where you live, would differ the two. I am currently running a 195. In hotter climates I would use a 195. In colder 180. However, you are right, the OEM spec is 195.
Guess that depends on who you ask. My intentions were to help people flush their system and help people better understand the cooling system. Thank you for watching.
I tried to bleed the air before the flush... It seemed fine and was bubbling slowly, then all of a sudden the radiator started Erupting like a volcano! I have no clue what happened, the reservoir stayed full the whole time also.
@@jeremykopp9859 thanks for the reply. The weird thing is that the temp gauge never gets above halfway (210 degrees)... But the water is bubbling in the overflow/ reservoir. Sorry for rambling, I just don't understand why the temp is okay/ fan kicks on at the right time, but the reservoir is boiling/ bubbling still.. I hope you all have a great day.
@@joshuakalaniparks9084 your overflow tank is working properly and actually doing its job. Based on your description, I would have steer towards your thermostat at this point. You may want to see if your thermostat is opening fully. If you have a faulty Tstat it could cause the temp guage to maintain even temp range but cause the overflow and heat in the expansion tank. Odds are, you have a bad tstat. Hope this info helps.
@@jeremykopp9859 thanks for the information, I will replace that ASAP,. I was thinking I should get a new radiator cap for good measure. -? Can't a bad radiator cap cause issues also?
The thing to check is your thermostat and housing. Yours is a cruddy stock unit. A 2000-2001 will develop a head crack at 80k. That will also cause overheating.
Hi! i have a 99 jeep Cherokee..Im having a tough time with a horrible thing that happens everytime i hit potholes or am on the freeway and drive over a bridge gap or anything like that it shakes my whole jeep ..very scary ..what does that and how can i fix it ?
oh i am going to drain my radiator now and so funny i go to o'rileys and i would've gotten Dex anti freeze ..UNTILL i saw your video thanks i dont need anymore trouble im learning and trying to be man -free of auto mechanics..i need to depend on myself not a service center ..ok man free was kinda weird..:) but i want to learn myself .
What you are experiencing with the steering is what we refer to as “Death Wobble”. Yes, it is very scary and can be fixed with steering stabilizers and sway bars and links.
I am happy this video has helped you out and you are wanting to learn how to fix these issues on your own. I teach my daughter never to rely on a man and fix things if possible. I salute you for that. Let me know if I can help with anything.
@@jeremykopp9859 first off ..i drained and filled my own radiator with the help of this video THANKS!!! ok so i heard my tires should be at 36 in winter and 46 in summer what do you suggest? and i want to replace my radiator hoses..can i just take them off 1 by 1 replacing as i go..and will it hurt the radiator or engine to have them off long enough to replace..does that makes sense? because i did what you did and it worked perfect easy..but i think my hoses from radiator to engine are a bit squishie ..oh God lololol
Fun fact, my 2002 TJ came from the factory with G-05 OAT (Edit: That was a typo, it should be HOAT) type coolant. I believe that was the first year Daimler-Chrysler used G-05 in Chrysler division products , although Daimler had used it in Mercedes-Benz products for years. Prior to 2002 (2001?) Chrysler used old school green color IAT type coolant. What was odd about the 2002 factory fill was that even though it was G-05, Daimler-Chrysler dyed it orange rather than the traditional yellow used for G-05. Why in the hell they decided make it look like dexcool, I have no idea. Later on Mopar branded G-05 was changed to the traditional yellow.
Alright, just a heads up for whoever lands on this video. It is not as easy as the video makes it to be. 1. Removing the hose clamps is easy but installing it back, specifically the one by the air filter is very hard. Space is limited. 2. They drain 3 gallons of coolant but when you try putting back 3 gallons, it won't take all 3. I was only able to get 1 gallon of straight antifreeze. I regret not buying the 50/50 mix since 1 gallon of that would have been better than 1 gallon of straight coolant. 3. Flushing the fluid from the top hose, nothing came out. Dont know if i wasted 10minutes of just making a mess. 4. These do yourself videos make it easy. But i wish i could have my 2.5 hours back. I will pay jiffylube the 150$ they quoted me before trying to do the job myself. I ended paying over $50 for gallons of straight coolant, distilled water, and hose clamps. This is easy if you have time to do it. I had to get the kiddos fast food for dinner cause this took longer than it was worth doing. Yes i was at an incline nose up.
Your thermostat needs a hole drilled in it to "burp" the system.......plus it's easier to buy the Prestone flush kit and just install it on the heater hose going in the tstat housing........lastly premix the antifreeze in a 5 gallon bucket before putting it in, or play the "little bit in at a time, then add water game." Our family owned a garage and wrecking yard.....
Just a heads up to whoever lands on this comment. DO NOT take your XJ to a Jiffy Lube for a radiator flush. They do not know how to do it properly. They left air in my system and I overheated/blew my head gasket 10 miles down the road. I was without a Jeep for a couple months and have to take them to small claims court now. Pay more and take it to an actual automotive repairs shop, or ask a mechanic friend to help and bring a six pack. Do not go to a ‘fast food’ type of mechanic if you care about your vehicle’s health.
It all depends on how hot your system is when you shut down. Not too mention the current temperature of your surroundings. There is a number of factors involved with this question. Lets just be safe and say, give it 45 minutes after shutting off.
You should have used the Peak Global Lifetime (which is available in concentrate, by the way) instead of that silicated IAT green coolant. The silicated IAT green is outdated, obsolete stuff.
@@jeremykopp9859 I don't remember you mentioning it in the video, what caused you to select that Racepro coolant? It's cringe-worthy watching this, when you had the ultimate coolant in Peak Global Lifetime available right there.
I definitely said PEAK is a good coolant and I don’t have anything bad to say about it. The reason I put Racepro in my system(this go around)is this, I wheel a lot and Rick crawl as well. I have found that the Race Pro has kept my engine at high RPM, slow speed in high heat applications, the coolest to this point. Again, Peak is great and I do use it in my other vehicles.
@@jeremykopp9859 What other coolants have you ran to compare? Scientifically, an IAT silicated green coolant has the worst thermal efficiency of any available automotive coolant. This is because this type of coolant uses silicates to coat the cooling system passages to inhibit corrosion. This coating acts like a thermal blanket and can reduce thermal transfer efficiency by as much as 10%. Modern OAT coolants, Peak Global Lifetime being one of the absolute best available, are silicate free and do not coat the system like this inhibiting heat transfer. Unfortunately, once silicates have coated your system, they're very difficult to remove. Even with repeated flushes, it's hard to eliminate them completely. Not to mention, this type of coolant has a 2 year max service life, usually dropping out their inhibitors long before that. By contrast, OAT coolants typically will last 5 to 10 years, the best of them like Global Lifetime will last indefinitely.
All the research I've seen suggests to not NOT use water as a coolant. Especially tap water. Tap water has electrolytes which can cause corrosion in your cooling system. If you must use water then use only distilled water ONLY DISTILLED WATER. Also, water does not have the lubricants to lubricate your cooling system which coolant has. Using water can cause damage to your engine. This information is readily available, and I think you are giving bad information.
Absolutely agree. Water will cause rust particles and it will look like mud. You can use it as a flush agent for a day or two at the most. But once your system is clean change it to coolant
Water is not the best option boiling point is 212 operating time is most of the time 210 I ran water in mine for a few days no problem so you’ll probably be fine if your just flushing the system but I ended up blowing a freeze cap so just use 50/50
When I spray water into the upper radiator hose it just builds up and sprays back out. It does not go down to the lower hose like yours does. I have tried wrapping a towel around it and that did not help. What can I do?
I stand corrected. The XJ was the FIRST unibody in production by Jeep and therefore stands for eXperimental Jeep. Later they introduced the ZJ in a unibody form as well. However, at the time of production, the XJ’s were the only unibody made when introducing the XJ. Thanks for watching and appreciate the comment.

You can add water to dexcool, but it has to be distilled. I’d recommend adding distilled regardless of type but its important with dexcool.
great vid, subbed.
How was your thermostat opened to flush through the housing? The car was off not sure how the coolant gets through
Remove it before hand
I was reading that the mishimoto had issues with the transmission lines. Have you experienced any issues? Of the install? Or I guess cooling as well?
Thank you for watching. No, I havent had any issues with the trans lines or cooling. It all transferred very smoothly.

Drain it on steep downhill fill on steep uphill. Thermostat housing will rust around thermostat. Easy fix will run cooler when done.

Where did you get your antifreeze at if you don't mind me asking ? I am tearing my TJ down starting next spring and when it goes back together I would like to try that antifreeze your using . Take care and be safe and looking forward to more of your videos.
Thank you very much! I appreciate you watching. I agree, the Dex coolant puts off a awful smell. It’s deceiving as it smells like the coolant is burning but it’s not. I purchase the Race Pro Anti from Advanced Auto Parts. It’s pretty much all I use. Let me know if you have any other questions. My next video will be up soon and it will be how to install the custom gas tank skid plate. Thanks again for the view!
Thank you for letting me know where to get the antifreeze at. There is a Advanced Auto Parts in our area on Washington Street. Looking forward to your Gas tank skid video. Take care and be safe.
@@moabwheeling yeah autozone nor o’Reillys had race pro. So I went and bought the second in line he recommended. Which was Peak antifreeze.
I think that is the most quiet 4.0 engine I’ve ever heard. Is there a specific engine oil you use?
I've seen the XJ on Matt's Offroad Recovery put louvers on his hood and a huge radiator in it.
I am actually going to put a fiberglass hood with scoop on next. Definitely will help with airflow and heat distribution. Thanks for watching!
We have very high temp during the 65% of the year, in Mexico border ,my XJ 2000 never receive a good maintenance during my last 5 years of use ,the cherokee the last year support during 3 hours running trap in high traffic without moving, 5:30pm at 38-39 C , this event and others histories make me see with proud this warrior, after that invest on it to take more care , i dont use A/C in my personal vehicles, but the truck have mounted the system, i decide remove the ac radiator , and runs very vey fine reduce easy the heat more than 1/8 of temp. An under the capo,and have a good fast capacity to cooling when running, the old radiator was dirty and reduce the capacity to refresh ,actually the activation of the electric fan was reduced,🫡💪🏻👍🏼😎 of course you need to be crazy ,to leave the A/C but is not imposible. God bless you .
Good info but isn’t your thermostat in the closed condition since it’s cold and how can you flush with a hose through that?
That’s what I’m wondering, tried to flush my jeep but would not flow through thermostat
@@jameswiththejeep2562 to flush mine I remove the lower hose so it drains the radiator AND block. Not really a flush but totally drains the block. I did that, drove it a few miles then did it again.
I left this comment before you told us what XJ meant, so Im sayin what I think it stands for.... X-cellent Jeep! HA!
Where did you get that front emblem? I have a 2000 classic and all the emblems were crusty so I replaced them with black emblems. Is it from a different model? I’m having a tough time finding one that will fit the curve of the front
I ordered all new emblems for the front, back and sides. Ordered them from Mopar. A bit speedy but great looking and quality.
@@jeremykopp9859 thank you. I already replaced the rest of them including the 4.0 badge but finding that front badge to fit is tough, I appreciate it
Xj is the factory code for production, and is assigned based on chassis and trim.
Nice video. The only critique I would say is that anti-freeze is also anti-boil. It increases the boiling point of regular water. it also changes it's flow rate so that it does not cavitate inside the water pump. Regular water is not the best, 50/50 is the best. Water will get you home.
Do you have to remove the t stat before sticking the hose in the housing while flushing?
No you do not.
Does the t stat not prevent you from flushing the system ?
No it doesn’t. You can still flush the system with a Tstat in. However, if you are only flushing the block, you would want to take it out.
Distilled water only. Running tap H2OH will corrode your cooling components. Big difference.
How ABOUT THE WATERT RESERVOIR? Beside there is a special out let for the flush, there is a flush hole on the side, we live in the south so I removed the thermostat period.
Good point and yes, another point of access.
I am going insane my jeep stays on for 5 mins and it doesn’t sit in the funnel it shoots out like a volcano so I have to turn it off!! Not sure what’s going on
I would mix my coolant outside of the system just to know I have the right mixture
That is definitely a great way to do it. Very good point!
That's how it's done in garages.....5 gal buckets and a funnel.
Where did you get those taillights
Can I fill the system with straight distilled water even if I have coolant in the block? I just replaced the water pump but there is still some green coolant sitting in the engine
Yes, you can fill the system with straight distilled water if that is your only source. I would highly recommend that you use a good antifreeze as to protect the engine and the coolant system with the proper elements included with antifreeze. Distilled water is a great source for your system if you have no other choice. It is not a good long term method but does work. Distilled water does not have the coolant protectants needed for your engine and the proper lubrication that benefits the cooling system. However, distilled water is a good substitute for a temporary addaditive.
Coolant has lubricant in it so it lunes the water pump. You don’t want to run straight water.
Lubes.
The fan clutch shouldn’t spin no more than a quarter to station with a flick. Maybe half
Ok if i am in Middle Eastern country where temp in summer can go to 125F the coldest days only 75f. What would be an acceptable thermostat? I found in local parts store a 160 thermostat.
That will work fine in your climate
nice trokita ese
What year that they came up with that
Would this be similar with a 1997 cherokee XJ by any chance?
Yes it would. 97’s have the inline 6 as well. Thank you for watching.
What rims and tires are these?
How do you get water to go through the thermostat housing. My water just spits back out
I know this is old, and you probably figured it out. But some water will come back out, but if all of it is, that's because your thermostat is closed completely, and you're gonna have to take it off. That's what I had to do, and it made a big difference, not just on the water flowing through but on how much of that old dirty coolant got washed out.
Mine sits right under 210 always. I still have to flush the coolent system but is that too hot?
No. If your sitting below 210 that is pretty normal. Do you know if you have the 180 or 195 Tstat in?
@@jeremykopp9859allright thanks. And I have no clue. I bought it like a month ago.
210 is the sweet spot
What about the coolant reservoir
Run a 180 or 195 T stat? Standard is 195. Thx.
Thank you for watching! Pending on where you live, would differ the two. I am currently running a 195. In hotter climates I would use a 195. In colder 180. However, you are right, the OEM spec is 195.
How come the water going into the engine while the car is off. I assume the thermostat is closed??
Tengo exactamente la misma duda. Salvo que haya quitado el termostato pero no lo indica
Where did you buy the racepro antifreeze?
Thanks for watching. I bought it at O'Reilly's
Great video but I can run water here in Colorado XD
experimental jeep is what i saw somewhere
OK is this a video on how to do a coolant flush or a video to mesmerize your jeep?
Guess that depends on who you ask. My intentions were to help people flush their system and help people better understand the cooling system. Thank you for watching.
Checking in 1.5 years later - I'm guessing you replaced the engine because it was showing almost NO oil pressure lol
Lol... no, the only reason for the 0 oil pressure was a bad oil pressure sensor. I replaced it and we are solid now.
Extended use of just water will cause cavitation and or rust.
Regular water pump? No aftermarket E-fans
You didn't show replacing the fluid in the overflow tank.
I tried to bleed the air before the flush... It seemed fine and was bubbling slowly, then all of a sudden the radiator started Erupting like a volcano! I have no clue what happened, the reservoir stayed full the whole time also.
Sounds like your flow is restricted somewhere in the system and causing it to heat up. Definitely need to do a full radiator, core flush.
@@jeremykopp9859 thanks for the reply. The weird thing is that the temp gauge never gets above halfway (210 degrees)... But the water is bubbling in the overflow/ reservoir.
Sorry for rambling, I just don't understand why the temp is okay/ fan kicks on at the right time, but the reservoir is boiling/ bubbling still..
I hope you all have a great day.
@@joshuakalaniparks9084 your overflow tank is working properly and actually doing its job. Based on your description, I would have steer towards your thermostat at this point. You may want to see if your thermostat is opening fully. If you have a faulty Tstat it could cause the temp guage to maintain even temp range but cause the overflow and heat in the expansion tank. Odds are, you have a bad tstat. Hope this info helps.
@@jeremykopp9859 thanks for the information, I will replace that ASAP,. I was thinking I should get a new radiator cap for good measure. -? Can't a bad radiator cap cause issues also?
Yes, a radiator cap not holding pressure will cause problems as well. Some cases you will see it steaming and blowing fluid out the cap as well.
The thing to check is your thermostat and housing. Yours is a cruddy stock unit. A 2000-2001 will develop a head crack at 80k. That will also cause overheating.
Hi! i have a 99 jeep Cherokee..Im having a tough time with a horrible thing that happens everytime i hit potholes or am on the freeway and drive over a bridge gap or anything like that it shakes my whole jeep ..very scary ..what does that and how can i fix it ?
oh i am going to drain my radiator now and so funny i go to o'rileys and i would've gotten Dex anti freeze ..UNTILL i saw your video thanks i dont need anymore trouble im learning and trying to be man -free of auto mechanics..i need to depend on myself not a service center ..ok man free was kinda weird..:) but i want to learn myself .
What you are experiencing with the steering is what we refer to as “Death Wobble”. Yes, it is very scary and can be fixed with steering stabilizers and sway bars and links.
I am happy this video has helped you out and you are wanting to learn how to fix these issues on your own. I teach my daughter never to rely on a man and fix things if possible. I salute you for that. Let me know if I can help with anything.
@@jeremykopp9859 ..thats exactly it!!
@@jeremykopp9859 first off ..i drained and filled my own radiator with the help of this video THANKS!!! ok so i heard my tires should be at 36 in winter and 46 in summer what do you suggest? and i want to replace my radiator hoses..can i just take them off 1 by 1 replacing as i go..and will it hurt the radiator or engine to have them off long enough to replace..does that makes sense? because i did what you did and it worked perfect easy..but i think my hoses from radiator to engine are a bit squishie ..oh God lololol
195 is OEM, not 180. If everything else on your cooling system is sorted 180 will be too cold
Fun fact, my 2002 TJ came from the factory with G-05 OAT (Edit: That was a typo, it should be HOAT) type coolant. I believe that was the first year Daimler-Chrysler used G-05 in Chrysler division products , although Daimler had used it in Mercedes-Benz products for years. Prior to 2002 (2001?) Chrysler used old school green color IAT type coolant. What was odd about the 2002 factory fill was that even though it was G-05, Daimler-Chrysler dyed it orange rather than the traditional yellow used for G-05. Why in the hell they decided make it look like dexcool, I have no idea. Later on Mopar branded G-05 was changed to the traditional yellow.
Lmao oat was 2013 lol u tube certified? Wheres you ase or Chrysler certs??? Viper tech here look me up lmfap
Alright, just a heads up for whoever lands on this video.
It is not as easy as the video makes it to be.
1. Removing the hose clamps is easy but installing it back, specifically the one by the air filter is very hard. Space is limited.
2. They drain 3 gallons of coolant but when you try putting back 3 gallons, it won't take all 3. I was only able to get 1 gallon of straight antifreeze. I regret not buying the 50/50 mix since 1 gallon of that would have been better than 1 gallon of straight coolant.
3. Flushing the fluid from the top hose, nothing came out. Dont know if i wasted 10minutes of just making a mess.
4. These do yourself videos make it easy. But i wish i could have my 2.5 hours back. I will pay jiffylube the 150$ they quoted me before trying to do the job myself. I ended paying over $50 for gallons of straight coolant, distilled water, and hose clamps.
This is easy if you have time to do it. I had to get the kiddos fast food for dinner cause this took longer than it was worth doing.
Yes i was at an incline nose up.
Sorry you didnt have a good experience and this video was not helpful to you.
Your thermostat needs a hole drilled in it to "burp" the system.......plus it's easier to buy the Prestone flush kit and just install it on the heater hose going in the tstat housing........lastly premix the antifreeze in a 5 gallon bucket before putting it in, or play the "little bit in at a time, then add water game."
Our family owned a garage and wrecking yard.....
Just a heads up to whoever lands on this comment. DO NOT take your XJ to a Jiffy Lube for a radiator flush. They do not know how to do it properly. They left air in my system and I overheated/blew my head gasket 10 miles down the road. I was without a Jeep for a couple months and have to take them to small claims court now.
Pay more and take it to an actual automotive repairs shop, or ask a mechanic friend to help and bring a six pack.
Do not go to a ‘fast food’ type of mechanic if you care about your vehicle’s health.
Can I do this 20 minutes after it cools down
It all depends on how hot your system is when you shut down. Not too mention the current temperature of your surroundings. There is a number of factors involved with this question. Lets just be safe and say, give it 45 minutes after shutting off.
Why is the rear sagging?
It appears to be sagging because I have some weight in the back cargo area but, it is also on a angle. There is no sag with normal conditions
Yes it’s experimental Jeep
Heater core ?
I did blow the heater core out as well. Great point though. I never did a video on that.
You should have used the Peak Global Lifetime (which is available in concentrate, by the way) instead of that silicated IAT green coolant. The silicated IAT green is outdated, obsolete stuff.
Peak is a very good solution as well. Thanks for watching and appreciate the comment.
@@jeremykopp9859 I don't remember you mentioning it in the video, what caused you to select that Racepro coolant? It's cringe-worthy watching this, when you had the ultimate coolant in Peak Global Lifetime available right there.
I definitely said PEAK is a good coolant and I don’t have anything bad to say about it. The reason I put Racepro in my system(this go around)is this, I wheel a lot and Rick crawl as well. I have found that the Race Pro has kept my engine at high RPM, slow speed in high heat applications, the coolest to this point. Again, Peak is great and I do use it in my other vehicles.
@@jeremykopp9859 What other coolants have you ran to compare? Scientifically, an IAT silicated green coolant has the worst thermal efficiency of any available automotive coolant. This is because this type of coolant uses silicates to coat the cooling system passages to inhibit corrosion. This coating acts like a thermal blanket and can reduce thermal transfer efficiency by as much as 10%. Modern OAT coolants, Peak Global Lifetime being one of the absolute best available, are silicate free and do not coat the system like this inhibiting heat transfer. Unfortunately, once silicates have coated your system, they're very difficult to remove. Even with repeated flushes, it's hard to eliminate them completely. Not to mention, this type of coolant has a 2 year max service life, usually dropping out their inhibitors long before that. By contrast, OAT coolants typically will last 5 to 10 years, the best of them like Global Lifetime will last indefinitely.
you should have flushed the heater core, thanks though
I did flush it. Should have put it in the video. Unfortunately I didn’t. Thanks for watching!
All the research I've seen suggests to not NOT use water as a coolant.
Especially tap water. Tap water has electrolytes which can cause corrosion in your cooling system.
If you must use water then use only distilled water ONLY DISTILLED WATER.
Also, water does not have the lubricants to lubricate your cooling system which coolant has.
Using water can cause damage to your engine.
This information is readily available, and I think you are giving bad information.
Absolutely agree.
Water will cause rust particles and it will look like mud.
You can use it as a flush agent for a day or two at the most.
But once your system is clean change it to coolant
If you elevate the front, the water bleeds better.
You are correct
Water is not the best option boiling point is 212 operating time is most of the time 210 I ran water in mine for a few days no problem so you’ll probably be fine if your just flushing the system but I ended up blowing a freeze cap so just use 50/50
What wheels?
I have the Allied Beadlock wheels on this one.
@@jeremykopp9859 DOT approved?
When I spray water into the upper radiator hose it just builds up and sprays back out. It does not go down to the lower hose like yours does.
I have tried wrapping a towel around it and that did not help. What can I do?
Remove the thermostat
Great video but OEM temp for thermostat is 195, not 180. 180 is acceptable, just like it's acceptable to be wrong these days. :)
My bad indeed. Thanks for watching.
Wrong about why the XJ is a unibody only. The ZJ Grand Cherokee is also a unibody.
I stand corrected. The XJ was the FIRST unibody in production by Jeep and therefore stands for eXperimental Jeep. Later they introduced the ZJ in a unibody form as well. However, at the time of production, the XJ’s were the only unibody made when introducing the XJ. Thanks for watching and appreciate the comment.
Away with you pedant.
What hose do I clamp!? Wtf
You clamp all hoses when reinstalling. No need to clamp any hose when flushing. WTF??? Lol...
