How to Service and Repair a Radiator Cap on Dodge Ram 3500?

Keep the cleaning of the radiator cap gentle by using soapy water; strong chemicals could harm the seal inside it. Holding the cap by the neck and looking at it, the bottom valve should freely open. In case the rubber gasket has grown big enough to prevent the vent valve from working, replace the cap. After that, look down at the cap, keeping it upside down, see if any light comes through where the vent valve and rubber gasket meet; replace it if there is any light. Check to see that the new cap does not have a spring, but is intended for storing excess coolant; pick one with a completely sealed diaphragm spring and a rubber gasket. The correct cap will allow coolant to return to the radiator easily.
