How to Inspect and Replace a Radiator Cap on Chrysler 300?

You should first put the radiator cap at eye level, then ensure that the vent valve open at the bottom of the cap. Swollen rubber gaskets may keep the vent valve from opening, so the cap needs to be changed. Then, while upside down, check near the vent valve to see if the rubber gasket is letting light in; if so, you should change the cap. A cap that cannot hold the vent closed should be used in place of the worn cap. You should always use a replacement cap that has a completely sealed diaphragm spring and fits the top surface of the radiator filler neck sealed by a rubber gasket. Wearing the proper cap will make sure coolant moves back to the radiator.
