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

Make sure that when dealing with 2.0L/2.4L vehicle engines, only use the proper cap part number, since the caps are not the same as those for 3.5L/2.0L engines. To check, turn the cap up and if the vent valve opens at the bottom, then pick it upside down and it should stay closed. Replace the cap if it becomes clear that the rubber gasket has swollen, if some light is noticeable between the vent valve and the rubber gasket when the engine is upside down, if the gasket underneath looks too thin or if the cap has suffered engine overheating more than once. If you have 3.5L/2.0L diesel engines, always double-check the pressure cap part number since the parts are not interchangeable. Check that the cap is right side up; the vent valve should remain shut but open as your finger is pressed against it. If the rubber gasket has swollen, light can be seen between the vent valve and the gasket, the gasket at the bottom is thinning or the cap has helped with more than one engine overheat, replace the cap with a replacement that has a spring to hold the vent valve closed.
