How to Inspect and Replace a Radiator Cap on 2007 Chrysler PT Cruiser?

Place the cap with the top upwards and ensure the vent valve at the bottom is open. If the rubber gasket is too swollen and doesn't let the valve open, you should replace the cap. Then, turn the cap the wrong way up and look inside from the valve to the rubber gasket for light; if you can see any, you have to replace the cap. Make sure the replacement cap is designed to work with coolant reserve systems, since this design is required for the coolant to be sent back to the radiator and select a cap without a spring that keeps vent shut.
