- My Jeep Grand Cherokee's check engine light came on and it turns out I need to replace the thermostat. It's a $20 part, but while I was doing that I thought I'd do a coolant flush as well. It's a simple and cheap job that you can knock out in 20-40 minutes. Hopefully my DIY video can give you the confidence needed to complete this project. Feel free to leave questions down below and like and subscribe to my video to see my follow up project where I replace the thermostat.
Below is the full parts list for everything that you're going to need to do this job.
Tools needed:
Bucket or drain pan -
Funnel - amzn.to/3lBHvSx
Clear Plastic Tube
8mm Hex Socket - amzn.to/3kfAEOR
3/8" Ratchet Drive - amzn.to/3nKskJd
Parts required:
7 Quarts of Zerex Coolant - amzn.to/3kh2DOp
at least 7 quarts of Distilled Water - get at local supermarket
Optional but recommended:
Lint-free paper towels
Safety glasses (required)
Gloves (optional)
Cardboard (great for catching spills)
Feel free to comment below, thumbs up this video, and subscribe to my channel so that I know to make more just like this in the future.
Thanks for watching!
One thing I forgot to mention is remember to burp the cooling system after you fill it up. If you hear a sound, like water rushing through pipes, you probably have air in your system. If you'd like a video on how to burp your system, comment here and I'd be happy to make one.
Please n thank you
Great video. I was just about to ask where the air bleeder screw is and how to bleed the air out, cause I hear a gurgling sound in my system when I start the car in the mornings. Thanks.
That would be nice, lol
For anyone else who comes upon this video, there is a bleeder screw on top of the thermostat you can use to bleed air. When I did the first flush, I couldn't get hot air to come out of the vents. Flushed again but kept that bleeder screw open as I refilled the radiator. Heat worked so I think the first time I had an airlock. You can also carefully loosen that screw as the engine is running and get more air out.
Also as others have mentioned, 2013 and on the manual calls for OAT, not HOAT.
oregon jeep fam - thanks for the videos
I have to do the exact same thing to my 2013 Jeep Grand Cherokee Limited 4x4 same color light blue...
That was just the radiator coolant, did you get the coolant from the engine block?
Great vid! Having an issue with my heat not working and the temp gauge fluctuatiing dramatically. Thinking I might have the wrong coolant and also checking the thermostat/maybe radiator fan
Sounds like you're on the right track. I don't think it's the thermostat. A bad thermostat fails open and the temp is consistently off. Might be the engine temperature sensor.
thanks for saving me money.
My 2018 has a different coolant reservoir.
That's a good idea with adding the drain hose. What size hose did you use?
This is what I need to know
@@Dale_Higgins I did this and used 1/4" hose and it was not big enough. I would get 1/2" and you can just hold it there if it doesn't fit snugly and stay on by itself
How did you attach the plastic tube to siphon the old coolant? Thank you!
If you look at about 2:21, you'll see the red knob of the petcock. Right below that knob is where you can attach the hose. If you have the correct size tube it will fit snugly on the valve. You should use a 1/4"-3/8" hose.
@@Moretimethanmoney thank you!
Should not tell people they can add water if they want. That is bad info. If it is a new car it will void warranty. If is pre diluted do not add water. I repeat do not add water if iz pre diluted. And I have a 2016 grand cherokee it takes the oat. Be sure you get the right one. It matters.
Couldn't agree more with everything you say. The number one advise I would give everyone is read the manual and the instructions. The anti-freese I use needs to be mixed and it has a chart showing how much to mix. Also the 2013 is when Jeep switched from HOAT to OAT. As you mentioned, you have to use the right one! Mixing the different types of anti-freeze can cause some major problems. Here's a great discussion on the different anti-freese types and the confusion that Chrysler has created. Thanks for feedback! Keep it coming.

I think there is a way to burp it, look it up.
Good video, so at the end of the video did you only have to add 1.5 gallons of straight antifreeze since the block already had distilled water in it, or did you have to add more water after adding the 1.5 gal of antifreeze, it was a little confusing there at the end
I had to add more water after adding the anti-freese. The anti-freese you use should have a chart on it that explains how much water to mix with the antifreeze to get mixture correct. You can also get an antifreeze tester to double check your mixture.
this was for my girlfriends 2014, I got 2 gallon of the concentrate Mopar oat, after I flushed it with distilled water a few times, I put a gallon and a half of concentrate in, then took the remaining half gallon left and mixed it 50/50 and topped off until full. Worked out great thanks!
How many times do you flush the system? Just once?
You should repeat the cycle of running distilled water through the system, running the car for 10 minutes with the heat at full blast, and then draining the system until the coolant that comes out is clear. Then you know you've gotten all of the coolant out of the system completely.
My question is how do we know what mixture to add back in? If you flush a few times times then most of what is in the block should be water.
You should drain out the water then close the drain and follow the instructions for the mixture on the antifreeze.
@@Moretimethanmoney what I'm saying is you can't drain it out of the block, which is why you have to flush it a few times to get get the old antifreeze out of the block. So when you are finished flushing, most of what is in the block is highly diluted and mostly water. So if you add a 50-50 mixture at the end, the overall concentration will be less than 50-50. If that makes sense.
@@kevinbright1 I don't worry about it too much. Some people mix it then pour it in. I personally pour the water in and then pour the antifreeze in and try and get it close to 50/50. I use a cheap antifreeze tester like this one to test the mix amzn.to/3TmPtPW and then adjust if I need to.
@@kevinbright1 have a 5.7 which takes 4 gallons of coolant. When draining you get a little less than 1 gallon of water so try and force out some water in the block if possible then just add 1 gallon to the radiator then the other gallon in the overflow and water as necessary. That's what I do. If it's a 3.6 it will very.
But yeah adding 50/50 to a water flushed engine will make it more than 50 water and less than 50 antifreeze.
So it's been little over a year since putting in HOAT coolant instead of the correct OAT coolant. I'm curious what kind of damage has happened from doing that?
The main danger is mixing HOAT and OAT. That is very very bad. Mixing coolants can cause them to gel and destroy your entire cooling system. Very expensive to fix. But if you flush out all of the old coolant, you should be safe. Using the recommended type of coolant will ensure that tubes and seals don't deteriorate. Having the wrong coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket. Jeep engineers spend a lot of time figuring out the chemical composition of the coolant and how the rubber and metal of the coolant system will react with it and using something other than what is recommended throws all of their calculations off. Your Jeep will run fine, it just won't corrode and wear the way it was designed to. Honestly, you probably won't notice the difference. Just make sure you do a thorough flush and fill and you'll be fine.
To follow up with @matraz10 comment, best I can tell, your 2013 JGC takes OAT not HOAT. Why did you put HOAT in it? And did it cause any damage??? And your Amazon link to the G05 coolant says it only goes up to a 2012 model right on the bottle.
The user manual of 2013 Jeep Grand Cherokee v6 states OAT should be used as antifreeze, which has a purple color. But my truck has pink..... 🤔
Guess it comes down to, did it come from the factory with pink or from the previous guy? 🤔
@@Moretimethanmoney The factory fill looks orange/pink from outside, which looks like HOAT. The manual says OAT, which normally is purple.
@@psq298 Found this great discussion online. Hope this helps. www.jeepgarage.org/threads/mopar-engine-coolant-2013-cherokee-overland.216365/
I've heard the OAT will change color after 3 or 4 years of running it. Purple to pinkish.
You literally skipped all of the important parts.
Please elaborate for everyone else. I'm not a professional so I'm always looking for ways I can improve or things I could have done better.
