How to Identify and Inspect the Correct Radiator Cap for Various Engine Types on 2008 Dodge Avenger?

Verify the correct pressure cap part number for 2.0L/2.4L and 3.5L/2.0L engines, as they are not interchangeable. Inspect the cap's vent valve and gasket; replace if swollen, if light is visible between the valve and gasket, or if the cap has endured multiple engine overheats.
