I recently changed the waterpump, radiator, thermostat and got a stress test done, was told the gaskets are fine but the car is still overheating. What else might cause the overheating?
My car has 150000 miles.
My car has an automatic transmission.
Hello, thanks for writing in about your 2010 Chevrolet HHR. For an issue like this, you may want to look at the fans while the car is on to ensure they are turning on and off. Also, it may be a faulty temperature sending unit.
