    Help needed: Jeep suddenly overheating after changing the thermostat

    Most importantly you need to use the OEM thermostats. Chrysler has 54,000 on back order against their supplier so they are hard to find. I called around and found one about 2 hours away. Service manager told me the only 2 after market ones that they have had some success with has been the Dorman...

    Overheating at highway speeds

    Sorry should have been more clear, I tracked down an OEM Mopar version at a dealership in Ontario CA. It was $100 but once I put it next to the Napa one it was shocking how much different it was in terms of throw and ID measurement. Once I replaced the water pump with the new gasket it still...

    Overheating at highway speeds

    Yes, and I have a snap on pressure testing kit with gauge so I can watch the pressure rise and transfer coolant into over flow and back again to insure there is no space in system. I also have a co2 test kit that I used to check for cracked head or blown head gasket. As the coolant started...

    Overheating at highway speeds

    I am also having the same issue, have installed a high cap radiator, and everything else all new I mean everything has been upgraded or replaced, same issue. Heavy head winds or high speeds and engine over heats can get it to 250 easy especially up hill.
