2022 Rubicon JLU Overheat Warning

[Darrell82]

Looks like this is quickly becoming a big issue with the 2.0t. That's what I have on order. Starting to get nervous. I guess you need to make daily coolant checks going forward.

I bet this will turn out to be a quality control issue during assembly with cooling components. I really like the 2.0 Turbo but no new vehicle should be using coolant!!

Wow...hope you're under warranty. Review your states lemon law just in case.

I have an extended Mopar warranty and it covers it.

Not just 2.0T. Mine is 3.6

Great!! I opened a case with Chrysler customer care hoping they will investigate why some wranglers are having coolant problems.

I wonder what type of coolant is used in Wranglers. Need to have a canister of it just in case.

Use only MOPAR OAT 50/50 mix Antifreeze.

That's right. I guess people will just have to check their new vehicle, daily, for a couple of weeks, to make sure they don't have the issue.

What's the difference with this one? Manual said MS.90032?

If you go over on the 2.0T thread, you'll see what it is. I had the same thing happen. What the common problem is, there is a flange between the lower radiator hose and water pump. Two bolts hold it on. They were not properly tightened at the factory. They come loose and it pukes the coolant out. I just tightened mine back up and so far, they are still tight. It's a QC issue at the Jeep plant.

I’m taking delivery of a 4xe Rubicon today with the same 2.0L, do you have a pic of which bolts you’re talking about so I can check. Delivery is through a carrier, not at the dealerahip, otherwise I’d have them check. TIA

The below is the concentrated. This one has to be premixed before using. 50/50 with distilled water..FYI.

The above is the premix 50/50 concentrated and distilled water mix. This one is ready to just use without any more premixing.

But it shows 50/50 prediluted too for MS.90032.
I guess MS.12106 and MS.90032 prediluted are the same?

Just make it simple. Go to your Wrangler Dealers parts department. Tell them that you want a gallon of Mopar OAT 50/50/ mix Antifreeze. Good for 10 years, or 150,000 mile whichever comes first. That is all they need to know to sell you the correct antifreeze. Plus it will say it on the bottle.

Yes! Happened to me today! 2022 with same engine. It only takes 3 miles to go from cold to overheating. Calling the dealership first thing in the morning Would love to know what this issue with yours ended up being.

Update: mine was just that….the bolts underneath had backed themselves out emptying one of the coolant compartments….no warning on the dash and no leaks in the driveway. 2 months old and I had to replace the engine under warranty. Jeep mechanic said he out Loc-Tite on the new bolts
