If you have noticed your Pt Cruiser overheating, don't worry, your not alone. . . . .
thanks to it's dual hose operation. Two cheap tweaks will include changing the radiator cap (it may be faulty, and causing your radiator http://www.singapore-aircon.com/ to malfunction), and/or affect the thermostat and gasket. When you initially notice your Cruiser overheating, you have to immediately check the coolant degree of your car.
Low coolant could possibly be the obvious culprit here, but be careful when should you are taking the radiator cap off! It is planning to be hot for a while after you shut off your car!.
