Man, I really like your relaxed attitude when explaining how things work, you are very thorough. Thank you !
Yah that super suave posture in the beginning . One cool dude
Been in the automotive business for 25+ years and concur with all you presented here....welll done
The Bob Ross of mechanics 😅💗thank you
I appreciate how mellow you are, it made me feel a lot more relaxed about having a go at fixing this problem myself. Great presentation and very informative.
I love your tutorials I have 96 Jeep Cherokee classic and every time something breaks this is where I end up
I love how informative and professional your videos are. Good work man
no prob bob, thanks for watching!
thanks for watching!
when i got my xj the blades on my auxiliary fan (the electic one) where gone . i went and got a new one , installed it and wired to a toggle switch . greatest choice ive ever made . for the most part i can control my engine temp :)
Lmk about the install idk shit about the wiring
Great video, You certainly cannot cover every possible issue but you covered 95% of them. Like your systematic explanation. I could used this as a learning tool to teach my kids about how engines work. Can you do one on brakes and oil pressure next? Hats off you. Thanks
ya no problem, thanks for watching!
I thought I mentioned that briefly somewhere but if not, thank for the heads up!
The clutch fan on my '88 Cherokee didn't budge with the engine off. It still spun when the engine was running, but the clutch was seized. I found a couple of fans at a junkyard that still spun freely and swapped out the original for one of the junkyard fans. Had to pull the radiator, but got it done.
👍
nice video you for got blown head gasket
Thanks, Me too!
You covered more then anyone so far👍 although one guy out there talks about factory clamps and how to check for a weak hose. Thanks a bunch friend. Now I have a lot of work to do.
Great video.....must have been other mechanics who gave you thumbs down out of jealousy. You told everything an inexperienced mechanic needs to know!
thanks buds ! couldn't agree more , i know i learned something thanks again!
Good mechanics give information freely, dispel misinformation, because keeping your car in proper working order is just good business.
Replacement of the viscous clutch on the mechanical fan will suck volumes of cooling air through the radiator,replace it,if you have overheating problems,as there is really no way of telling if it is working correctly ..Replacement of the viscous clutch can make a major difference to the running of your jeep, never overlook or pass the replacement of the viscous clutch by.
Hey just went through a night mare for a weird over heating problem in my 2010 Jeep Liberty found out after a thermostat then water pump then radiator and five days later found out that the thermostats from part stores will not work in this vehicular you have to get them from car dealer because rectory thermostats are specials ; my car would over heat as I got up to speed of 65 if I stayed at 55 or slower it would not over heat this is just info if your out there having problems like this yes it was a feascail but it runs awesome now
never F around with aftermarket cooling system parts, leave that for suspension
cool, thanks for watching
Thanks, if you feel inclined to tackle it yourself there are a few good vids out there on YT. Not sure if Eric the car guy has one but he is pretty good.
When flushing the system , I recommend also reverse flushing . Especially the heater core . I have had heaters that were only warm come back to life with a reverse flush - directly on the core . Deposits build up over time and cut down on the heat . Also on the radiators , the tubes can get restricted . You can use a laser thermometer to check ALL the tubes . They are usually colder in the middle of the radiator if clogged . You can also put your hand on the tubes to check for cold areas - if you can get it in there . BUT you don't want your hand near an electric fan , even when not running . If hot , they can still turn on with the ignition off .
So my radiator is at 175 all around but in the center it’s cool. I can touch it. I thought it was because the clutch fan was pulling in air the most right there. I checked it right after taking the upper fan shroud off then I could stick my hand and a lazer thermometer everywhere with out the clutch fan in the way
@@Arizona_Vineyard I would think if the tubes are cold in the center of the radiator , it's because they are clogged and not allowing hot coolant to get through them . It will cut down on the ability of the radiator to get rid of the heat . I would replace the radiator . Also check the thermostat and circulation from the water pump . A reverse flush of the entire system, including the heater core , will bring everything back to full potential . You are working on a complete cooling system . Don't just slam a radiator in without doing a complete job . Don't forget to check the cooling fans . And don't run straight water .
@@billsmith2212 I just had my 454 dually redone. I changed everything to stock. Someone had an idea for a show truck but on a really tight budget. I decided to pull everything out and redo it from stock. Only thing is I can’t keep it from overheating after the outside temperature gets above 100. I even spent 1200 on a new ac. Once it gets 230 I turn heat on and sweat it out. It’s all factory now. Even the old engine did the same thing
@@billsmith2212 I just got off the phone with the builder and he said the center is going to be cold because that’s where the fan clutch pulls the most. The coolant sensor and thermostat is what he said to look at. Those thermostat’s are junk now and they see alot of them failing in the last 5 years
@@Arizona_Vineyard If the center is cold , the tubes are blocked . Because you are in an extremely hot area , you may want to upgrade to an oversized radiator and cooling fans with more CFM . There may also be a water pump with more flow . But if the coolant moves too fast , it may not allow it to give up the heat when going through the radiator . However , the larger radiator may balance that out . Look into radiator shrouds and air dams that direct the air flow . I would think there are shops that specialize in cooling systems , especially in Arizona . A specialist may have a complete system to get the temperature down . I would start with that blocked radiator core .
forgot two very common causes:
1. cracked head, block, or head gasket,
2. plugged radiator.
Also, sometimes the water pump impeller will erode away or just spin on the shaft without its bearings going bad so you need to discuss a way to test its actual flow.
Excellent comment ..
Check the 9 things I have in the video and a few more that people have added in the comments.
This is the most comprehensive among all cooling system videos. Thumbs Up!
What about a partially clogged radiator?
@silverbird58 what is comet?
Hey Matt, I've watched this video several times and changed out pretty much the whole cooling system in a 99 XJ. New pump, thermostat, cap, rad is less than 2 years old and the hoses look good and fairly new. I've also flushed several times. I thought it may be the "spring" in the lower hose so I changed out the lower hose and sure enough, no spring. I've been to several local auto parts stores but they don't have any with springs. So I used a new one hose from Autozone. It does seem more stiff than the old one, but she's still overheating and after running, antifreeze upchucks out of the reservoir. Does this sound like the lower hose is collapsing and if so, where do I get a spring? Thank you for all your videos, I watch them all the time:)
robpossible I've read about this and apparently only the Factory hoses had springs and they were for filling the system with antifreeze quickly on the assembly line and were not needed after that. Another theory, modern hoses are stiff enough they don't need springs anymore.
😭😭😭 I have the same problem with overheating I have changed the water pump, changed the radiator, change even the gasket but still overheating
Its a head gasket unfortunately.
Man let me tell you sometime you what you are talkin about appreciate you people that watching video he knows what he is talking about again thank you young man thank you thank you thank you I will share this video with anybody that has a problem with their cooling system thank you thank you thank you thank you stay safe and again I appreciate you young man
This is a very good video. I was expecting the host to bark at me, but he kept a calm, cool demeanor. Well done!
2:56 made me laugh for some reason.
@Coleman Kairo d I’m I’m Che
Ahha And When He Was On A Steep Hill Hahahaha
An entire tree and a piece of paper 🤣
NOTE: Internal Clogged (Engine Block Passage) is the hardest and you could pull all your Hair out before you realized it's in the Engine Block ://.
What to do then??
I replaced the water pump and the thermostat but my truck is still overheating what could be the reason ????
@@twinewinfieldwinfield6734 - You have to do an " Extreme Flush ". See this video here: czcams.com/video/0aaLVCpVS08/video.html
Thank you very much for putting the time into this video. Its people like you who save people like me a lot of money! Thanks again
The engine diagram was helpful. But great video overall and the uphill vsm downhill camera trick was great. Bravo.
If you are over heating and your upper radiator hose is bulging could this be a radiator cap that is not opening?
+Mike Meegan i would think maybe a clogged radiator.
+BleepinJeep potentially more complicated. Here's the latest. Thanks! www.jeepforum.com/forum/f310/overheat-upper-rad-hose-bulging-3586106/
www.jeepforum.com/forum/f310/overheat-upper-rad-hose-bulging-3586106/
+Mike Meegan - Sorry but if the " Radiator Cap " is " NOT OPENING ", then the " RESERVOIR " would " OVERFLOW " first. I agree with " BleepinJeep ". If the " Upper Hose " is bulging. 3- Things you check. #1. The Radiator Clogged. #2. Internal Clogged (Engine Block Passage). #3. The Thermostat is NOT opening correctly.
Mike Meegan k
the oil pump screen or oil filter.the aintfrezze is new fans good every thing good with fluid new caps temp gauge good readyater. .could be the head gasket
the motor gets hot nothing else the oil red hot .
Really helpful and solved my issue. Thanks! Plus, I learned a lot about motors in general.
Wow, Im genuinely impressed. Sonetimes when the car gets stressfull, its nice to hear someone being calm. Good reset while figuring things out
3:38 LMAO wtffff lolllllllll
Pkproduction217 foreals.. good video but that was over the hill exagerated lmao
The issue I'm having is that the car only over heats when I turn the ac on. The ac works' but the car over heats if it's kept on. If I don't use ac the car run just fine. Can you please help?
Did you fix your problem? I'm having the same issue with my Nissan Maxima
Nah, but some told me that it's a sign of the head gasket going bad'
Bcs I put a new radiator, hoses, thermal stat. And it's still doing it
+AR-X I Yea I took my car to the dealer. Same thing coolant leaking in to the spark plug cylinder. New engine needed.
you should have replaced the head gasket!
Dude!! Best tutorial out here on youtube. Thank you so much for taking your time
I know there are some writeups on it out there, not sure about videos. But if you wait a few months I might have one as my new cherokee still has the closed system.
I have a 2003 honda 140k that's been always overheats, I pour coolant into it and it's fine with highway driving it's not until I stop or idle that the temp gauge begins to climb. Around the time I stop/idle after driving the a/c will change from blowing hot air to blowing cold air. After it overheats I'll pull it off to the side and check the components the overflow tank looks to have spitted out all the antifreeze towards the bottom and some on the air intake. I've had a new thermostat installed, fans checked/electricals, new radiator was installed. I thought it was a bad head gasket but there is no white pummels of smoke or a milky dipstick and I had a mechanic do a chemical test and it came back negative. What might be wrong?
Thank you
Have u check your water pump dude?
Had a master ASE tech check it out, blown head gasket.
James Whyte my 2001 honda civic does same thing. hopefully it's not a blown head gasket tho.
check cooling fan switch.
James Whyte it's a Honda... that's why :)
Is mayonnaise a coolant?
NO, do NOT put mayonnaise in your car's cooling system!! It will cause damage and does not have the proper viscosity that your car's recommended coolant needs to have. Not to mention mayonnaise will freeze in winter conditions, and does a poor job at cooling your car!!! Do not listen to this guy trust me, mayonnaise is not a good idea for putting in your car's cooling system, it's a common urban myth that it can work!!!
@@micaarzur Alright fine, deli mustard it is.
@@shark180 much better.
Are you talking about sandwiches?
I believe you helped me out when it came to step 8 and 9 that's what I haven't heard on other videos so thanks a lot good video
oh and btw i love how you explained the whole coolant system and i love that you speak clear english too, and not too fast. this is a great vid and i am going to save it so i can actually go thru each step to figure out what is wrong with my truck and why it's overheating. watching ur vid make me(YES A WOMAN) confident i will find what the problem is then get it fixed. so thanks so nuch and yes i have subscribed to your channel!!! thanks: yvonne k. tennessee
its best that you dont put your keft hand on your waist.
Why
@@OysterPir8 bro is been waiting 3 years for the reason 💀
Keft?

he sounds like that high pitched old fella from family guy hahahaha
Thank you for the details man, great video 🙌
Thanks Man, I appreciate it!
I just found out a clogged or bad fuel filter can cause also cause a car to overheat traxxas.com/forums/showthread.php?188533-Fuel-Filter-overheating-problem
dude,thanks for this info.was most informative.have a jeep cherokee 12 years.has always run warm or hot.head cracks/gasket etc. will check these things you mentioned.
its on the list
sure, thanks
Hey Man thanks a lot for the video, it helped me figure out my stupid mistake. I have a 01 Intrepid rt 3.5, and it kept overheating after i tried to fix a mess with the fan wires. I had one of the fans pushing air instead of extracting it, I never would have thought to look at the direction they were blowing. All fixed now. Guy i bought it from thought it was the water pump, but he just didnt have things connected correctly. The reservoir tank was connected wrong too. Saved myself a few hundred dollars at the shop and future headaches thanks to this video!!!
This helped Me a lot. Thanks for sharing your wisdom.
No Prob, Thanks for Subscribing!
This is a very though tutorial. Thank you for your knowledge, ots greatly appreciated
did you replace the radiator cap? or you might have air in the system. is this a pressurized reservoir? if so it could have a hole in it.
Awesome video! Thnx a ton 4 helping me diagnose and fix my cooling system problem! Saved my trooper,and my headache! Thanks again!!
Teresa Waters sure, no problem!
If you watch some of my wheeling videos you can hear what the power steering sounds like when going out. I think my Secret location one was the worst.
thanks
on my jeep the same relay works the fan no matter the reason for it coming on. I have no idea but would start by figuring out what tells the relay that the A/C is on then check the wiring from there.
depends if it is a closed or open system. I'm guessing it is an open system in which case it just keeps it from spilling and keeps dust out.
They are both separated in different tubes. just like the oil and coolant both go into the engine but they are in different compartments and dont mix. The radiator cools the tranny just fine on stock applications but some people choose to add on another in line external cooler for performance applications, lets day for towing, racing, hillclimbing, etc.
Excellent, very clear explained I recommend it.
Fernando Garcia Golding fuck you
Thank y for the vid very helping how ever you need to explain if the head has an issue and how to .... thank you again
thank you hazim. 100% right
no sweat, thanks for subbing!
Was not expecting all of the humor but certainly loved it! 🤣
if I read the posts below correctly, you are not having any overheating issues? Are you sure the coolant isnt flowing and you just cant see it flowing?
Great video. Very knowledgeable. Thank you for taking so much time to do it
thanks for subscribing!
Thanks for this vid....trying to troubleshoot my a parents Jeep from far away and this definitely helps
hmm, not really sure on this one... if the system is cooling good how do you know the elec fan needs to come on?? does the fan work when you turn the a/c on?
Thankyou u tube for all its videos they really were a big help
Good tips. Thanks. I have some things to investigate now.
I ❤ the way you explain, clearly. And how you get right to it. Now would be perfect. If you were working on my type car.2004 Toyota Avalon
I know the basics are pretty much the same. BUT
excellent video well done in explaining over heating and your 8 point check
Great vid! Thanks for posting.
Very thorough , Easy to understand ,good video !
Very informative video, loving the goggles towards the end.
Good video. I am a full time autotech. It is rare, but I have seen water pump impeller's seperate from the mainshaft. It won't leak or wobble, but it will not move water. It is common on VW engines with plastic impellar, but I have also seen it on chevy's. Also air in the system can cause overheating. Honda civic's with the heater core up higher that the radiator cap are bad about this. I use a special funnel to bleed out the air. Keep up the good work.
Really good work, liked it a lot. My car had a Thermostat Problem and after replacing with new one all is working fine :). Thanks a lot and wish you the best.
bad radiator cap or plugged overflow hose
Great steps thanks. I'm a shade tree but start panicking & thinking the worst moving down from there. usually buying replacing parts I didn't need too sweat and replace. Nice to have a mellow guy go through steps I already know, slow me down, think. B.T.W. my wife loved it. She cant change flashlight batteries, but understood every word. Finally!!! she wont blow another head gasket Grrrr. I too stressed the importance of always wearing eye protection while working, thanks Jason. Phoenix , AZ july 2016 114 degrees today.
that sounds right about the relay, I'm not sure which on it would be but just start sapping relays until it works then you'll know. Sorry I don't know much about electrical but you might want to ask the question on your favorite jeep forum and see if someone there has an answer for you.
I learned a lot from this video, thank you
really good explaining! subscribed!
could be, but also could be something else making it run hot, then boils up when stopped. check the fan and radiator cap first.
Very helpful thank you sir
that really depends on if you are offroading it or not and how you drive. Offroad I would say 33's for the dana35, 34's for the 8.25, 33's for the dana30 and 36's for the dana 30 with chromoly.
i had the same issue a while back and it was the clutch fan. sometimes they aren't bad but just aren't as good as they should be. try putting a new clutch on there and see if that fixes the problem.
very good explanation i can understand everything you said thank you very much
Good video👍 Very thorough thank you
Great video man. Keep up the good work.
Hi
That was a very well done job. Thanks!!
Thanks buddy. I appreciate the help. God bless.

Very well explained. Thank you
Great video ! Thanks for sharing.
Yes, you should consider yourself lucky! but did you get the stock 195° thermostat? do you have a 3 core radiator? and to know the real temp you need a laser temp gun.
