I have 2006 jeep liberty it's overheating while I'm driving but not when it sits at idle and it's blowing cold air out ....what could be wrong...
Fix the leak first, you don't want to burn it up, have the radiator flow tested, it might flow ok at idle but when the water pump output increases it can't handle it thus an overheat while driving, and now would be a good time to change the thermostat if it has never been done.
I've replaced the water pump the thermostat still have a leak somewhere under the jeep liberty but the heat is working now and its not overheating anymore what could it be
