    2015 Jeep Wrangler Overheating Issue

    Cold start: Heater core hoses hot to touch around 140-150. Lower hose hot to touch around the 200+ mark. Upper hose never got hot, as coolant bubbling up the rad neck and spilling over a bit. I shut off car at 213 degrees.

    2015 Jeep Wrangler Overheating Issue

    The spikes happen when moving/ at speed. Coming to a stop for traffic, it might inch slowly upward and then comes back down. These extreme changes only occur while moving. About to head out to get another jug and do this burping again. I posted pics of my rad fins, if your have any...

    2015 Jeep Wrangler Overheating Issue

    So I've put about 250 miles on it since I attempted to burp the system last night, covering all sorts of terrain and grades, including some light offroading (this is my job). Mostly stayed around the 210-222 range. Towards end of the day today it began the weird extreme fluctuations - would...

    2015 Jeep Wrangler Overheating Issue

    But did the cooolant ever erupt back up out the radiator? Special funnel or not, why did the fluid rapidly rise with engine idling for me? Had my oil changed yesterday by same shop that did the flush (that I stated I'd had done in my initial comment) and they said no residue/milkyness in the...

    2015 Jeep Wrangler Overheating Issue

    The digital reading is all over the place, fluctuating 20 degrees or more in seconds. I'm really leaning toward air in the system myself, and I've heard how difficult it can be to completely burp it. With regards to a rad cap.... I purchased a new one from Autozone that is 18lbs. I look at...

    Hi, sorry for the late reply. I didnt bookmark the page and lost this discussion! I cannot say for certain it was burped...properly..? We are going to do this ourselves this weekend after getting a coolant funnel kit.

    2015 Jeep Wrangler Overheating Issue

    Hi, thanks! I'm not able to work with the dealer (not going into reasons). The shop who did the initial flush after purchase did a pressure test before flushing. No issues, held pressure fine.

    2015 Jeep Wrangler Overheating Issue

    I just purchased a 2015 that began overheating on my way home from the lot. We have been chasing down this issue for 4 weeks now. The overflow tank is staying full and having to add coolant to rad about every 2 days, unless I've put on some miles. There is residue in the drivers side pocket...
