Q: Possible bad thermostat

asked by on

My car is overheating. I think it's the thermostat.

Your problem could stem from various sources: the thermostat may be stuck, the system may be plugged, the fans may not work, or the engine head gasket may be blown. You might only need to replace the thermostat, however, a thorough cooling system diagnosis would be needed to be sure. I recommend having a mechanic, such as one from YourMechanic, run a diagnostic test for your overheating issue, and recommend the best path to repair.
