Has anyone replaced thermostat on the 3.6l? I have a small coolant leak. Dealer thinks it is thermostat. They couldn't get to it today, I need truck over Thanksgiving, so they sold me the part. Can't find many videos of this job online. Has anyone done it? Is it essentially the same as on the older JKs with the 3.6l?

trust they sold you a MOPAR. Also view Burping the system after replacement.

Still don't know why he didn't take 2 mins to remove the TB and have more clearance to work with

Thanks -- wasn't sure the JL and JT procedure was the same as the JK procedure. Turns out it was.

I'm not 100% but there might be a gasket at the throttle body. If it isn't reusable, then it would add cost and time to the service. Just a thought!

easy enough to follow, tips very helpful too. Maybe ID the MOPAR part # for the replacement thermostat?
