How to Service and Repair a Radiator Cap on Dodge Ram 1500?

For beginning radiator cap fixes or replacements, remove it from the radiator and check that the surfaces that touch inside are clean. Wet the rubber gasket with water and securely attach the cap to your pressure tester or its equivalent. Turn on the tester pump to increase the pressure on the gauge to 104 kPa (15 psi). Should the pressure cap allow a reading below 97 kPa (14 psi), change it with a new cap. Keep in mind that a correctly reading pressure cap may not work with the radiator, so check the radiator filler neck and the top radiator cap gasket for any damage. Remember, these tools can detect even small air leaks that often don't mean the cooling system is having issues. Do not change a pressure cap just because a small coolant leak happens when the system is tested. To discover if the tool leaks after being reassembled, fill it with water, invert it and press the test cap again. When cleaning, only use water and a mild soap, because stronger solvents can harm the seal in the radiator cap.
