I am a full time truck driver by day and a part time mechanic by night. I watch these instructional videos just for fun and you are literally the only person on youtube i have seen do this correctly. I scream at the screen when i see people pour 50/50 blended antifreeze into a system that has just been flushed with water. Im glad you explained that you have to add full strength antifreeze equal to half the systems capacity and THEN top off with distilled water. Everything you explained really hit the nail on the head. Keep at it man. Great video!
If you were to run only water you would have several issues. First, the boiling point of water is 212 degrees F, just 2 degrees above the normal operating temperature of a Jeep 4.0. That means you'd most likely boil over if you used plain water (50/50 coolant has a boiling point of about 265 degrees F). And yes, another reason to run coolant/antifreeze is that when mixed properly, you will have a decreased risk of rusting any ferrous parts inside your engine (like the engine itself in the case of the Jeep 4.0). Rust is the reason that his coolant came out all brown and murky, it would have been much worse if he didn't have any coolant in the system at all! 2 gallons of undiluted antifreeze costs about $15 and it should last you several years.
micvee not true...water doesn't boil at 212 when pressurized as is the case of a typical cooling system... And actually water dissipates heat faster than coolant. So it works better by itself. But overall you are right.. You should run a 50/50 coolant mixture for reasons of freezing and very mild rust prevention.
This is definitely the most comprehensive flush tutorial I have found. I can't thank you enough for expressing how important it is to catch the old toxic coolant. The only other tip I might add would be to back flush the heater core with VERY light pressure from the hose, Especially on an XJ that could have a load of sludge and crap trapped in it.
Good video. One thing I did additionally on my 99 XJ was back flush the heater core since my heat was lukewarm even after a thermostat change. Boy did I get some great heat after that . There is a very simple video on doing that.....simply disconnect both heater hoses and run water hose through bottom heater core hose till all the junk comes out. Refill the whole system, let air burp out of cap with engine running and cap off. Fill your expansion tank to full line. Put rad cap back on after coolant wants to run out constantly. Took mine for a short drive, turn off, check level, add if necessary to expansion tank.......keep in min that the expansion tank level may go down as the engine cools so check your level after it cools and for good measure check your level for the next couple days and recheck for any hoses that may be leaking at the clamp area from being disturbed. Not a bad idea to replace all heater and radiator hoses at this time. One other trick I do while I'm in jeep maintenance mode that I do to every cherokee I own....yes I own a few, is replace all the battery positive and negative cables with an assortment Imget from the auto,parts store. I also run a new cable from battery negative post to one of the air compressor bracket bolts to give the engine a better ground strap than the deteriorated woven strap from the factory at the back of the engine near valve cover. One of my jeeps was burning out ignition could due to a weak ground and this fix cured that and also made the engine start up noticeably faster and the engine just feels much stronger after this simple and rewarding preventative fix. Happy jeeping!
Best instructional video I've seen for quick Jeep maintenance. Easy to follow step by step and straight to the point of what to do and how to do it. Thank you!
Then he used the garden house to pour water so the antifreeze was diluted. The animals wont die drinking it but will probably get cancer. Anyhow, it was a very instructive video. Will try it myself. Thanks.
Man, that was a great video. Well explained but simple for the layman. You guys that do these videos honestly are helping a lot of people in the world. Even if it might seem like a simple thing to do for some. Much thanks!
Great video, no bullshit, just an accurate, easy to follow explanation. This is the first winter since I bought my '97 xj so wanted to get some info before I did a coolant flush. Thanks!
Just got one of these Jeeps for 1k and I found this video. Watched a few more of this guys videos and now I know..... I HAVE TO SUBSCRIBE! Thank you so very much for the videos they are a great guide to getting me in the right direction for my new toy.
Excellent video, as always. I can't believe shops charge so much to do something simple. My dilemma is that I live in the city and do not have access to a hose. I can ask a friend, but I do not want to make a mess in his driveway. Maybe a DIY car wash place will let me get away with it..or ill just bite the bullet at a shop.
I went to a mechanic shop and they told me they needed to flush my system out. They made it seem like it was a big deal and charged me 125 dollars to do it. Just finished watching this video and I'm incredibly pissed that I paid those fu#@ers that much money to do it!!!!!!!! Thank you for making this video. Now I can do this $#!% on my own.
Jesse Riley well you got to remember time is money. It may not be that hard to do but probably took at least 1 hour. If the shop rate is like $95 and hour then you have to ad that to materials. It already cost a lot more to get someone else to do it.
That reservoir doesnt have a outlet of any kind near the bottom so if you fill it with water like a giant DONG SLOBBERER! Just skip the 8mm part and go strait to COCK POUNDING your own FACE!!!!
These 2 screws are difficult to unbolt. Another solution is to disconnect the small hose from the canister but not on the canister side but on the radiator side. Let this hose hang on a lower position than the canister and the gravity will empty the canister. You can do an extra flush with the garden hose from the top op the canister.
Neither way is. On my Jeep my issue right now is nasty sludgy rusty antifreeze that needs flushed out. I put down cardboard, and was really careful....and I still ended up with rusty spots on the concrete, haha.
You can catch it all and keep the rust off your driveway if your lifted by using a little wading pool. I don't know why everybody feels the need to criticize the boy for getting a little fluid on the ground
Question for all you good folks out there. When I pulled the top radiator hose off to start the engine flush, no water would go in past the thermostat. I had to pull my thermostat out before I could get water through. Is that normal or was this a case of a bad thermostat? The Cherokee overheated recently that’s the reason I got off my rear and decided to do my own flush. Living in Costa Rica, not only do I have language issues but have been warned repeatedly that the local mechanics shouldn’t be trusted. Thanks! And great video!!!
Bad thermostat snd do not put green coolant in a chrysler/gm vehicle it takes the orange/yelllow/red (OAT) Organic Acid Technology coolant/antifreeze or you will corrode the cooling system and all its parts with the green (IAT) Inorganic Additive Technology coolant/antifreeze
I took the thermostat out of my 95' today. It came out quite easily. Getting it back in with that lower bolt not clearing the serpentine belt- stupidity on Chrysler's part:-(. So now my 10 minute repair is going to take me half the morning tomorrow to put it back in- grrrrrr! This video was of great help, that petcock doesn't do anything to drain off the cooling system, you gotta pull the hoses! My other "DOH!" for the morning was having my bucket in the wrong place- my neighbor walked up to say good morning and have a chat for a few minutes, and I wasn't paying attention to where the water/antifreeze was falling. We got it cleaned up. TOmorrow I am flushing my heater core- always make sure you do that when you flush your system!
glad the video was helpful! That seems to be the way it goes sometimes. A 10 minute job turns into a much larger job because of one stupid bolt or part in the way
Now I have a cutoff tool just in case...haha. I have a feeling when I go to put in my lift next year it will come in handy..along with my reciprocating saw and my breaker bar/pipe setup. I might spring for a 30 gallon air tank and an impact gun before then, haha.
Hey Admiral great video i just replaced my fan clutch radiator and water pump and serpentine belt on my 92 cherokee after doing all this i looked in my original owners manual and iv never seen or heard of this but there is a engine block plug under the manifold for the coolant flush it said to leave the radiator cap on and remove the engine drain plug and drain cock and supposably it will drain everything the over flow and block everything do you know if this is not recommended ? Also i know you live in AZ where its all ways hot what temp does your cherokee run at ? I had mine jump to 230 while 4wheeling on the beach and i read that it is NOT uncommon for it to go that high but normal operating temp is 195 and thats why i changed everything now it goes as high as 195 but at night when its cool it doesn't go over 190 which im happy with but i worry when im on the beach again that it will shoot up again under the heavy strain does yours ever go up to 230 when 4 wheeling ? Thanks Admiral
thank you admiral. my 2000 jeep actually started doing this on me and I cant drive it. I figure it could be clogged so that is what I am going do tomorrow before work.
Hey! I was going through your video step by step, and I noticed when I turned my jeep on to let the flush go through the system that it started to creak here and there when I turned on the heat, is that normal?
when i’ve done mine i would run engine with heat on to get that dirty stuff out, but nowadays at over 60 years old i look for shop that has the flush system that pulls old stuff out and new stuff in its fast and no mess, of course it costs more be worth it
Would running water straight to heater core hoses with the heat switch turned to high and the jeep off be a better way to flush heater core or is running water through the lower radiator hose like you did doing the same thing?
Great video. I'm wondering why my jeep is overheating. I also noticed the coolant isn't draining from the reservoir. It seems like its not going through the system. What could be causing this???
I picked up an 89 XJ and the thermostat-heater core and water pump-heater core hoses were taken off. They also have the “T” inline for the pressure tank. My goal is to install the coolant filter but not sure where the four ends are supposed to be in accordance with the filter housing. You have any pointers?
Very informative. Currently working on fixing an overheating issue I have on my 2003 Jeep Grand Cherokee since moving down to the Phoenix area. May have to end up doing this. Didn't even think about adding coolant first. Quick question though, how much water did you use for flushing the radiator? I live in an apartment complex, and don't have the luxury of using a garden hose. I might just pour water in from the kitchen sink if it isn't too much.
You apparently failed to mention that you MUST have previously removed the THERMOSTAT! Otherwise water would NOT flow from the TOP radiator hose into the engine compartment to flush it out. The thermostat is a spring coil heat activated valve that opens up when maximum temperature indicated on the thermostat is reached to ALLOW hot coolant to pass thru and circulate into the cooling system for heat dissipation and to maintain a consistent operating temperature.
Do you fill up your overflow again or just leave it empty and let all the extra fluid come in? I'm new to owning a Jeep or a car I can work on and my overflow is full
I just took off all the Cooling system components on my engine and replacing everything. Can I just now or should I wait until I get all the new stuff back on? Thanks again as always Admiral -Fletch
Should mention that the thermostat being closed won't allow for a full flush of the engine block and removing it is not advised if you dont have to. Bottom bolt is a pita and the design of the housing is common to leak. Dont mess with it unless of course the stat is bad and needs replaced.
Question if when I try to out water on the upper hose by the battery of water returns back does that mean my thermostat is open and doesn’t let water thru?
My coolant looks clean and full but still going to clean the system, but I have one question: my coolant reservoir seems to drain very quickly so I sometimes run with no coolant in the reservoir, but the engine doesn't overheat. Do you know why this would be?
Any cylinder head cracks yet? Mine just cracked between cylinders 3 and 4 which is the typical spot. If you crack since this is a design flaw on the 0331 head for 2000 and 2001 get a TUPY head or one from Alabama Cylinder Head with a very improved casting.
I know it’s bad to use tap water when you fill the system to run. But is it worth it to fill it with distilled water when you flush it too? Or is this overkill
Thanks for the video, I plan to use this to help me change my 99 XJ soon. What I can't understand is we need to use distilled water and yet you use city water to flush it out. Surely some city water is still in the system and could cause long term damage?
Great guide. Just bought a 93 xj with overheating issues and just replaced the thermostat, water pump and fan clutch. Up next is a coolant flush for piece of mind. Hope that helps my problem. Is there anything I might be missing?
sounds like you've got the basics covered. If you continue to have overhearing issues you can get into fan upgrades and hood vents but i would do all of the things that you mentioned first because the other two won't do much if your cooling system isn't in good shape.
Hey, do you have any videos of replacing the Thermal Expansion Valve? Or ability to walk me through that? Haha.. I cannot find ANY info online for that!
When I spray water into the upper radiator hose water does not come out of the lower hose, it just builds up in the upper hose. Why doesn't mine behave the way yours is? 98 XJ 4.0.
thanks man helped me immensely. You in CA? I got a 01 Cherokee and it has some problems, I've been able to diagnose and fix some but there's others I have no idea where to start!
okay so i recently flushed, now it is overheating and smoking near where the upper radiator hose connects to the radiator. I am replacing the hose this weekend but it seems like very small leaks could be coming from the radiator wall where it connects? not entirely sure, wondering if you had any ideas.
@@iriehiphopgirl This guy had a defective thermostat, allowing the water to flow into the block. Another good way is to spray water through the heater hose that connects into the water pump. This is the bypass hose that bypasses the t-stat.
@@ethanwalton980 thank you so much for the advice! I ended up flushing out the system section by section, starting at the heater core. I inherited my 92 Jeep XJ and my mom hadn’t flushed the cooling system in over 5 years…. It was a doozy. She’s running good now though!
1999 Jeep cherokee sport 4.2 6 cyl. Great video, easy to do. I also changed the coolant sensor as well because my gage stopped working, it's working great now, temp is reading a constant 210 when vehicle is warm. The issue now, is I lost all my cabin heat! The heater was working great when I ran the coolant cleaner through it, and after the coolant change for the first day. But today the heater does not blow hot air anymore, just cool. The blower is working fine. Any clue why? Thanks for your help!
THANK YOU. I must have looked at 5 other videos, and none of those morons even showed how to find the drain valve, let alone how to work around the ridiculous set up by Chrysler. Best Video for this job!
Thank you very much for your video. It gives us newbies a chance to get around to actually do some work on our cars on our own. =) Great, helpful attitude. God Bless you.
Great video man I blew my top radiator mudding and got a professional flush and it didn't solve my over heating problem so I may think it's my water pump but first I'm doing exactly what you just did!?
Best thing to use when draining the system is a cement mixing tub there low and rectangular they catch it all. You can get them from a home improvement store. Because the fluid spills everywhere otherwise. You never really get it all in the bucket.
Rick C137 You never really did get it all in the bucket,, Another trick is laying out a tarp under the vehicle and and surround it it with any absorbent.. It catches all that doesn’t go into the bucket, soaks it up, and can be swept/scooped up pretty easily. I do the same thing for oil changes to protect the ground or garage floor. Thx Rick
I just want to know how you managed to get water to flow through the thermostat housing. If the thermostat is in place and functioning properly, running water into the top radiator hose should simply fill up the hose.
Undoing the plug from the bottom and disconnecting the small hose from the side of the cap then put the tip of the hose under the car and suck through it a little bit then gravity will do the rest and you rinse and drain your reservoir.
I had that happen to me once. I ended up disconnecting them for a few hours and when I connected them again they were fine. I think the connection can get loose at the horn itself and make the horn activate on its own
Not sure if you fixed problem, but there is a fuse that if removed, will turn off horn. Also if your check engine light is on, get codes read. If it says clock spring,that is your problem. Bad clockspring sends high voltage to the TPS causing rough idle and also makes your horn go off nonstop
I am a full time truck driver by day and a part time mechanic by night. I watch these instructional videos just for fun and you are literally the only person on youtube i have seen do this correctly.

Great tips. Thanks for the video. I'm getting ready to flush my 98 Cherokee out for the first time on my own and needed that advice.
"Don't spill it cause it kills animals" *Spills all over the place* LOL
ya that didn't work out as planned. Just had to clean up afterwards
Just thought that was ironic funny, I figured you took care of it. lol
Do you fill up the reservoir tank aswell after filling at the radiator gap?
Then he used the garden house to pour water so the antifreeze was diluted. The animals wont die drinking it but will probably get cancer. Anyhow, it was a very instructive video. Will try it myself. Thanks.

Would running water straight to heater core hoses with the heat switch turned to high and the jeep off be a better way to flush heater core or is running water through the lower radiator hose like you did doing the same thing?
did you use distilled water for when you cleaned it through? and how did you get it to be pressurized through the garden hose
Great video. I'm wondering why my jeep is overheating. I also noticed the coolant isn't draining from the reservoir. It seems like its not going through the system. What could be causing this???
Not sure if I just missed it but after you refilled the radiator at the end did you also refill the overflow?
When running water through the top hose, does it have to be warm to get through the thermostat ?
my fav. 4:47.... thank god you wernt looking at the hose lol.. yet another great video, tho!!
Thanks!
I picked up an 89 XJ and the thermostat-heater core and water pump-heater core hoses were taken off. They also have the “T” inline for the pressure tank. My goal is to install the coolant filter but not sure where the four ends are supposed to be in accordance with the filter housing. You have any pointers?
Very informative. Currently working on fixing an overheating issue I have on my 2003 Jeep Grand Cherokee since moving down to the Phoenix area. May have to end up doing this. Didn't even think about adding coolant first. Quick question though, how much water did you use for flushing the radiator? I live in an apartment complex, and don't have the luxury of using a garden hose. I might just pour water in from the kitchen sink if it isn't too much.
I can't remember off the top of my head. If you could get around 10-15 gallons, that should be enough to flush it.
You apparently failed to mention that you MUST have previously removed the THERMOSTAT! Otherwise water would NOT flow from the TOP radiator hose into the engine compartment to flush it out. The thermostat is a spring coil heat activated valve that opens up when maximum temperature indicated on the thermostat is reached to ALLOW hot coolant to pass thru and circulate into the cooling system for heat dissipation and to maintain a consistent operating temperature.
Do you fill up your overflow again or just leave it empty and let all the extra fluid come in? I'm new to owning a Jeep or a car I can work on and my overflow is full
I just took off all the Cooling system components on my engine and replacing everything. Can I just now or should I wait until I get all the new stuff back on? Thanks again as always Admiral -Fletch
Should mention that the thermostat being closed won't allow for a full flush of the engine block and removing it is not advised if you dont have to. Bottom bolt is a pita and the design of the housing is common to leak. Dont mess with it unless of course the stat is bad and needs replaced.
You're the man!
thanks!
Question if when I try to out water on the upper hose by the battery of water returns back does that mean my thermostat is open and doesn’t let water thru?
What do you do with the old coolant when you’re finished?
My coolant looks clean and full but still going to clean the system, but I have one question: my coolant reservoir seems to drain very quickly so I sometimes run with no coolant in the reservoir, but the engine doesn't overheat. Do you know why this would be?
Hey man, thanks for this video. Before I do this I was wondering... how long did you run the Jeep while it had the water/flush cleaner in it? Thanks!
***** Hi Mark. i ran the jeep just long enough for it to reach normal operating temperature (210ish). it took about 10 minutes or so.
Cool, thanks so much! I'm looking forward to doing this. It's amazing how much car maintenance is easy to do if you just know how!
Can I take off the other end of the hose instead and have as good of a drain?
Any cylinder head cracks yet? Mine just cracked between cylinders 3 and 4 which is the typical spot. If you crack since this is a design flaw on the 0331 head for 2000 and 2001 get a TUPY head or one from Alabama Cylinder Head with a very improved casting.
I know it’s bad to use tap water when you fill the system to run. But is it worth it to fill it with distilled water when you flush it too? Or is this overkill
Thanks for the video, I plan to use this to help me change my 99 XJ soon. What I can't understand is we need to use distilled water and yet you use city water to flush it out. Surely some city water is still in the system and could cause long term damage?
About to flush my xj this weekend and would like to know the answer for this also.
Nice job, dude.
Thanks!
cheers mate
Great guide. Just bought a 93 xj with overheating issues and just replaced the thermostat, water pump and fan clutch. Up next is a coolant flush for piece of mind. Hope that helps my problem. Is there anything I might be missing?
sounds like you've got the basics covered. If you continue to have overhearing issues you can get into fan upgrades and hood vents but i would do all of the things that you mentioned first because the other two won't do much if your cooling system isn't in good shape.
Admiral Off-Road okay, and thanks for the quick reply! Gonna subscribe now 😊
Drain wate,r
Drain water
How do you know when you’re completely done putting water or coolant in the system??? That’s the part I’m now confused on.
Hey, do you have any videos of replacing the Thermal Expansion Valve? Or ability to walk me through that? Haha.. I cannot find ANY info online for that!
I like this guy!
Good video 👍
Awesome!!!
When I spray water into the upper radiator hose water does not come out of the lower hose, it just builds up in the upper hose.
Why doesn't mine behave the way yours is? 98 XJ 4.0.
thanks man helped me immensely. You in CA? I got a 01 Cherokee and it has some problems, I've been able to diagnose and fix some but there's others I have no idea where to start!
Glad to hear it! I'm in Arizona
okay so i recently flushed, now it is overheating and smoking near where the upper radiator hose connects to the radiator. I am replacing the hose this weekend but it seems like very small leaks could be coming from the radiator wall where it connects? not entirely sure, wondering if you had any ideas.
Is it a plastic or metal side tank? I had a plastic one crack and had to replace mine
Hey so I got to the top hose flush with the hose and it's just spewing right back out. Not going to the lower disconnected tube. What's that mean?
Dude me too dammit
@@iriehiphopgirl This guy had a defective thermostat, allowing the water to flow into the block. Another good way is to spray water through the heater hose that connects into the water pump. This is the bypass hose that bypasses the t-stat.
@@ethanwalton980 thank you so much for the advice! I ended up flushing out the system section by section, starting at the heater core. I inherited my 92 Jeep XJ and my mom hadn’t flushed the cooling system in over 5 years…. It was a doozy. She’s running good now though!
1999 Jeep cherokee sport 4.2 6 cyl. Great video, easy to do. I also changed the coolant sensor as well because my gage stopped working, it's working great now, temp is reading a constant 210 when vehicle is warm. The issue now, is I lost all my cabin heat! The heater was working great when I ran the coolant cleaner through it, and after the coolant change for the first day. But today the heater does not blow hot air anymore, just cool. The blower is working fine. Any clue why? Thanks for your help!
Sounds like some air trapped in the system. The heater uses the hot coolant to warm the air that the heater blows into the cabin.
THANK YOU.
I must have looked at 5 other videos, and none of those morons even showed how to find the drain valve, let alone how to work around the ridiculous set up by Chrysler.
Best Video for this job!
Thank you very much for your video. It gives us newbies a chance to get around to actually do some work on our cars on our own. =)
Great, helpful attitude.
God Bless you.
Thanks!
Great video man I blew my top radiator mudding and got a professional flush and it didn't solve my over heating problem so I may think it's my water pump but first I'm doing exactly what you just did!?
Good luck! Hope it solves your problem.
donny moran any update on your overheating issue?
Great vid, thanks man!
thanks for the kind words!
Good job kid.
Best thing to use when draining the system is a cement mixing tub there low and rectangular they catch it all. You can get them from a home improvement store. Because the fluid spills everywhere otherwise. You never really get it all in the bucket.
Rick C137 You never really did get it all in the bucket,, Another trick is laying out a tarp under the vehicle and and surround it it with any absorbent.. It catches all that doesn’t go into the bucket, soaks it up, and can be swept/scooped up pretty easily. I do the same thing for oil changes to protect the ground or garage floor. Thx Rick
So how do I go about bleeding or burping my coolant if I have no heat? 😅
What if the water isnt flowing through from the upper hose and the lower hose
I just want to know how you managed to get water to flow through the thermostat housing. If the thermostat is in place and functioning properly, running water into the top radiator hose should simply fill up the hose.
I found out later that the thermostat had actually failed and was stuck open. You would need to remove the thermostat to do this
Undoing the plug from the bottom and disconnecting the small hose from the side of the cap then put the tip of the hose under the car and suck through it a little bit then gravity will do the rest and you rinse and drain your reservoir.
Thank you for sharing your knowledge. Do you know why my jeep's horn keeps activating itself, this is a very annoying problem. Thank you again.
I had that happen to me once. I ended up disconnecting them for a few hours and when I connected them again they were fine. I think the connection can get loose at the horn itself and make the horn activate on its own
Not sure if you fixed problem, but there is a fuse that if removed, will turn off horn. Also if your check engine light is on, get codes read. If it says clock spring,that is your problem. Bad clockspring sends high voltage to the TPS causing rough idle and also makes your horn go off nonstop
Great video ,u r a natural.
