Jeep Cherokee XJ Radiator Flush & IMPORTANT INFO!

[@gzrgldr8288]

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

[@altellan]

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.

[@tactlcal_bacon_bits4773]

@@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

[@killaklown1080]

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

[@altellan]

@@killaklown1080 A lower thermostat temp wont give you more heat.

[@andoniades]

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?

[@CharleyKen-l3f]

Thanks so much for the detailed video, very helpful. I wanted to share one small help I learned which seems to work: When burping the system, squeeze the upper radiator hose a few times because it's the highest point of the system and there will always be air there. Just 4 or 5 or so big squeezes should do it. Thanks again for sharing!

[@ericsxj1975]

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.

[@mhgregor]

Eric, just picked up on this video and your 3-year-old reply, and to Jeremy too: if you did want to specifically ensure the heater core was flushed, what would you suggest? Disconnect at firewall and run garden hose through as an addition to the above procedure? I have a 1997 XJ 2.5 tdi that I acquired in Jan (I live in Spain) and I want to do some preventative maintenance (flush the cooling system) but my heater performance is poor too. I suspect the previous owner may have changed the thermostat to a lower temperature one as it gets very hot here in summer (the vehicle has been in Ibiza most of its life and was probably a summer / beach vehicle at most), which could be a possible cause, but I suspect it's never been flushed either. So before I ruin a weekend taking the whole damn dash out to change the heater core for a new one, I´m wondering if a flush that includes the heater core and a standard temperature thermostat might fix my issue. Whilst it gets very hot here in summer, I live in the mountains and use the vehicle for ski trips in the Pyrenees. Thanks in advance for any ideas.

[@ericsxj1975]

@@mhgregor Yes but don't disconnect the heater hoses at the firewall, you can disconnect them at the front (at the thermostat housing and where it goes to the block.) Good luck!

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 😀

[@Dd-bk7rr]

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.

[@_el_del_bajo5_]

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

[@edwardl.990]

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.

[@davidward6366]

Yes, our local radiator man showed me the cascade trick years ago, IT works

[@edgaralvarez9686]

Does the t stat not prevent you from flushing the system ?

[@jeremykopp9859]

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.

[@scubasmith]

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.

[@bignspicy984]

What do you do about flushing the overflow tank?

[@Donmar21]

The OEM recommended thermostat is 195. Replacing only the thermostat from 195 to 180 will NOT improve a cooling systems performance or fix an overheating issue. The only job of the thermostat is to close off the cooling system (radiator) until the engine reaches operating temp (195 for the 4.0L). Once open, the efficiency of the cooling system ( radiator's ability to dissipate heat) determines the hold temperature. If your cooling system normally sits at 210, then it will sit at 210 whether the t-stat opens at 195 or 180 (opening at 180 will only delay the engine reaching operating temp). This is regardless of weather temperatures. If your cooling system has trouble holding temp in Summer heat (or overheats) then there is an issue with the radiator's ability to dissipate heat that a lower thermostat will not address. The stock XJ cooling system is more than adequate for the 4.0L when properly maintained. XJ's never had overheating issues when they were new. It is only common issue now due to lack of preventive maintenance and majority of XJ's close to or over 200K miles.

[@danhambrick6331]

That big ole honking winch in front of your radiator probably had something to do with your previous over heating issues...lol...

[@jeremykopp9859]

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!

In flushing out my heater core and doing a coolant flush, the owners manual said to remove the plug on the lower left side of the engine. I tried, but no go, so I drained the radiator, flushed out the heater with water (after unhooking the heater valve) and started to fill the heater using the top heater hose. It seems that feeding water into the heater pushed out coolant out the nipple that the top heater hose was hooked to at the thermostat. What a surprise that flushed the block!! Can someone verify that this is possible?

[@mohammedalrugaib4344]

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

[@jeremykopp9859]

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.

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.

[@jeremykopp9859]

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

I cannot advise running pure water in a cooling system. Water will corrode your entire system and it’s not a good day. It’s ok in a pinch, but do run some kind of coolant to properly protect your system. Not to mention it provides lubricity to your water pump

[@jeepcherokenumber1juansalv158]

Can I do this 20 minutes after it cools down

[@jeremykopp9859]

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.

[@PhantomPhaze]

195 is OEM, not 180. If everything else on your cooling system is sorted 180 will be too cold

Exciting jeep

Great video but I can run water here in Colorado XD

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.

[@keithlucas6260]

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.

nice trokita ese

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

experimental jeep is what i saw somewhere

[@coleperry1446]

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?

[@edwardl.990]

Remove the thermostat

[@rickhilliard2545]

8:17 into the video before any draining and then no video of the draining?..okey dokey then.

[@charpackage]

Great video but OEM temp for thermostat is 195, not 180. 180 is acceptable, just like it's acceptable to be wrong these days. :)

[@jeremykopp9859]

My bad indeed. Thanks for watching.
