I recently had a coolant hose and the thermostat replaced. But my car is still overheating. It is suggested that the Head Gasket may need replacing. Could there be other problems that causing the car to overheat. The car is not leaking oil or discharging smoke.

Napa has a coolant test kit for about $50 that will test your coolant to see if there is exhaust gases in your coolant, Once this test is done you will know if you have a blown head gasket

Do the radiator fans cycle on/off as the car heats up? If the fans do not run the car will overheat.
