Is Your Radiator Cap in Need of Replacement? How to Inspect and Decide on Dodge Durango?

To inspect a radiator cap, grasp it in an upright position with your hand level to your eyes; the vent valve should open at the bottom. If the rubber gasket has become so big that it stops the vent valve from opening, the cap will have to be changed. After that, turn the cap upside down so you can see at eye level. If you see light between the vent valve and the rubber gasket, change the cap. Substituting a cap without a spring is necessary to avoid shutting the vent. It is important that the replacement cap be made for a coolant reserve/overflow system, with a diaphragm spring and rubber gasket that seal to the radiator filler neck top, making sure coolant can return to the radiator.

How to Service and Repair a Radiator Cap on Dodge Durango?

Always use water and gentle soap to clean your radiator cap, because choosing harsh solvents may harm the seal. Hold the cap over your eyes, with its logo right side up and see if the valve opens; if it is stiffened by the rubber gasket, replace the cap. After that, hold the cap pointing down so you can see the opening between the valve and the rubber gasket; if any light appears, you should change the cap. Only place a cap on your radiator that does not use a spring to seal the vent; it should have a rubber gasket and a diaphragm spring that are completely sealed, made for a radiator coolant reserve or overflow system. Correctly choosing a cooling cap will ensure quick return of coolant to the radiator.
