• Q: How to Service and Repair a Radiator Cap on 2001 Dodge Ram 3500?

  A: To keep the radiator cap safe, wipe it with a soapy water mix and stay away from stronger chemicals. Stand your cap upright, with the bottom up and look for the vent; if it's blocked by the gasket, remove it and use a new one. Next, look through the cap's opening, upside down and level with your eyes and inspect for any light between the valve and the rubber piece; if there is light, change the cap. Choose a replacement cap that does not hold the vent shut with a spring and make sure it's built for a coolant reserve/overflow system, having a diaphragm seal and a rubber gasket that connects to the filler neck surface.
