coolant

I just bought a 2018 JL 3.6, it was a little low on coolant. The coolant looked like it was this color, more pink. I ordered the proper coolant for it which was purple, poured in about 3-4 ounces. I’ve heard that the purple coolant can turn pink over time. Im just worried, since it was used...

I was checking the fluids on this 2025 jlu wrangler rubicon I recently purchased and noticed that this black reservoir with black cap right next to the clear reservoir one might be a little low on fluid. I think this is the engine coolant reservoir, can someone verify this? I don't want to add...

Hi Everyone, I’ve got a 2021 Jeep JL 3.6V6 and having an oil leak coming from my oil filter/cooler housing seals. I’m planning on replacing with the new updates OEM housing which I hear has the updated webbing for the seals. My question is more for the coolant. How do you flush and replace the...

Started hearing a sound similar to when the heats on high , only from the passenger side. Doesn’t go away when controls are fully off. Quieter when stopped, gets louder with speed. Took it to a shop they said I have a hvac leak somewhere just air in the closed system. Not losing any, however...

Bought a 2020 Jeep Wrangler Sahara Unlimited with the 2.0L i4 turbo engine. About a year ago the Auxilliary Coolant Pump died and, at the time, there was no MOPAR part available to replace it. Everything was back-ordered for months, and the Jeep just had to sit there until a pump could be put...

Jeeps a 3.6. I had an oil change Friday afternoon. Saturday morning I drove about 30 miles, jeep began smoking from under the hood (white-ish gray, I thought it was gravel dust at first). Pulled over, the coolant cap was left off, completely out of coolant. Ended up driving it up a curb in an...

Hi all, I'm new to Jeep and I have a 2021 Jeep Wrangler JL Rubicon with the 3.6L eTorque engine. Under the hood, I see three coolant reservoirs — all have the same black caps and purple OAT coolant. Right now, reservoir #3 has a noticeably low coolant level — close to or slightly below the...

Hello, I had a radiator leak in dec 2023 and got my radiator replaced at the dealer( I know dealer, but had no other options at that time). Yesterday, I saw my engine starting to heat up and fan started blowing full speed in 65F weather and 45mph speed. Checked the coolant reservoir when jeep...

Hey y'all getting together a bit of a novel here to hopefully get some @JeepCares visibility and also add some volume to the chorus with this particular failure mode we're seeing on the upgraded 3.6 on the JLs and other Jeep platforms. But first a little bit history: I love wranglers. My first...

So I’m trying to understand more of parts and how my jeep works so when it comes to having issues, I’m not out spending unnecessary money on the wrong things. I’ve had ongoing issues with overheating and coolant related things. As an overview, I’ve replaced my 4 spark plugs, 2 of my ignition...

Whats the best way to flush the coolant on the 3.6 motor? With this motor/radiator not having a cap vs the previous years I'm not finding any videos/tutorials that best shows how to do it. Thanks

Hi all, I am working on my sons JL. ( 2020 JL 2.0) It is heating up, no leaks, fluid wasnt low. No mud on radiator, etc. I am assuming its the thermostat. I purchased a new thermostat, and the old one has a T connection that won't come off. Looks like the previous owner put some goop on it...

2018 Jeep Wrangler JLU Sport S 2.0 Back story: Jeep had an overheating issue. So replaced all 4 Spark Plugs, 2 Ignition Coils, 1 Ignition Coil Connector, Thermostat, and Heater Supply Hose. All that fixed my overheating issue. Then jeep “Exploded” lol just too much pressure (I assume I’m no...

So previously I was having overheating issues which I’ve since got the issues fixed. I replaced all 4 spark plugs, replaced cylinder 1 and 4 ignition coils, new thermostat, new heater supply hose. I had coolant in my tanks but my recovery tank was bone dry, so I filled it up and let the jeep run...

Jeep Wrangler 2018 JLU 2.0 Turbo So my issue has been that my jeep would overheat when I’m idling or driving constantly at a low speed. My temporary fix was to rev my RPMs 3k + for a few secs and the temperature would go back down. I changed out all 4 spark plugs, slot 1 and 4 Ignition coils...

2018 Jeep Wrangler JLU Sport S Turbo 2.0 I’m trying to understand if it’s necessary to have Coolant in the Coolant Recovery Bottle (Mopar Part # 68364312AC) either Minimum/Max level or completely dry. There doesn’t seem to have a straight forward answer. If “yes” that it’s necessary and required...

I've been trying to track down a slow coolant leak for the past 2 months, and today I finally saw a spot on the driveway. It looks like the leak is coming from the radiator. I can see an active drip from the drivers side lower corner of it (image below). My question is, for a driveway repair...

Hello all, First time poster here. I owned a Wrangler about 20 years ago, loved it, but due to life and family circumstances, waited a while to get another. Bought a brand new 2024 2.0 Sahara with 2K miles (dealer demo). I've had it for 2 months, put about 1800 miles on it myself. On my way...

Of course this happens today, crazy day at work so I haven't investigated deeply yet but if anyone could tell me where you think I should start I would really appreciate it. 2018 JLU 66k miles. I've been smelling coolant when exiting the jeep the last 2 times I've driven but levels look fine on...

Hi All, I was putting in a air compressor behind the left wheel well. I took some photos and I noticed later on when looking at the photos, the coolant line has some pink residue on it. Is this a cause for concern? Probably should bring it to the dealer to look at, right?
