[QUOTE="Cotton Valley, post: 464219, member: 26152"] So I am having a similar issue. 2015 Jeep runs fine with temps around 208-210 as long as I am running the heater full blast. But get it up to interstate speeds and turn on AC it starts climbing into the 220s - 240s. Never overheats but suddenly lose heat and (or it starts cycling from warm to hot so I know I have air in the line. When I stop it has completely filled the reserve tank. I had an aftermarket thermostat and thought that may be the issue so last week installed a MOPAR thermostat and a new tank just in case I had a leak. Still doing the same thing. Have a new cap coming tomorrow but if that doesn't solve the issue not sure what to do. I did get the radiator "no leak" system so I could let it sit there on an incline and burp the air out but still getting the issue. Any advice would be most appreciated..... [/QUOTE]
