CAN'T FIGURE OUT WHAT IS CAUSING MY CAR TO RUN HOT/ OVERHEAT

Asked by Mar 23, 2016 at 03:04 PM about the 2006 Chrysler PT Cruiser Base Convertible

Question type: Maintenance & Repair

I have a 2006 Pt Cruiser just hit 100,000 miles.. It over heated on my
husband so we drained the radiator which looked like straight mud. also
replaced the thermostat. That fixed the problem for awhile then one day
sitting at a red light it started doing it again.. as long as i have my heater on
it won't overheat and as long as I am moving.. I have to add anti freeze
every couple days and there is never any fluid in the reserve tank.. Any
suggestions would be greatly appreciated.. Thank you

It sounds like you may have blown a headgasket when it overheated, that is why the coolant loss. The other problem I see is the cooling system itself, if it was that bad chances are very high the the radiator is badly restricted and possibly some of the engines smaller cooling ports, you can try a power back flushing but I doubt you can get it all, but the coolant consumption should be checked out before spending any amount on it yet, it may not be worth it. So take it to a shop you trust and have it block checked, that will verify if the headgasket is blown.
