    Why is my 2014 Jeep Wrangler JK overheating?

    No. But it will overheat sitting in park also. Sometimes. RPMs too high? I’ve had these tires on it since 2020. I’m just assuming that’s where you’re going with this.

    Hearing air releasing at engine shut off?

    Today I had the hood opened when I cut the engine off and I heard a “poof” of air being released somewhere under the hood. Standing at front of jeep I had someone start and cut it off. It does it every time. I’ve never heard it before today. It sounds just like when you bump the valve stem for...

    Why is my 2014 Jeep Wrangler JK overheating?

    Well, my 2014 Jeep hasn’t been overheating since I burped system a few times last week. But wife drives 65mph max on the highway. I drove it for about 200 miles last Friday and when I would get up to 80mph + it would start to overheat. It hung out at 230 with the needle just over the mid line...

    Why is my 2014 Jeep Wrangler JK overheating?

    I should clarify - it’s orange (dexcool compatible) ethylene glycol. It’s honestly just what I’ve always used. No particular reason behind it. I’ve never seen purple coolant! Or pink! My daughter would love that!! So the last few days the Jeep has run fine. No overflow into reservoir...

    Why is my 2014 Jeep Wrangler JK overheating?

    Yeah it’s not clean which is odd bc I literally poured coolant in 30 seconds before this pic. The oil is good. I have to add oil before the next oil change , about a quart, each time. But it’s clean.

    Why is my 2014 Jeep Wrangler JK overheating?

    this is the steady flow overboard. Cold start immediately this happens. Goes down in a few minutes and I put a little coolant in and it comes right back out. I’ll try the combustion test this week. Hopefully not a BHG. I’ll have to learn how to do that too. Dang jeeps gonna make a mechanic out...

    Why is my 2014 Jeep Wrangler JK overheating?

    Yep. I have done and been doing that. This morning I burped and that’s when I added coolant and it pushes it back up and out. Then at 222degrees it was boiling and spitting coolant out of the radiator. First time it’s done that. How can orange coolant go in the radiator and over to reservoir but...

    P0420/P0430 with OEM cat on ‘07 JK

    I’m 99% certain they are good. spark plug 3 Was cross threaded (which is Bank 1 side) and I don’t believe it was changed last time. Cant say for certain. In the meantime Im hoping to use the fooler until I can rethread and replace that plug. If that’s not it, maybe it is actually the...
