Is Your Radiator Cap in Need of Replacement? How to Check on Dodge Dakota?

Supported at eye level in the vertical position, check that the vent valve at the base opens properly. Should a swollen rubber gasket stop the vent valve from opening, a new cap is necessary. Then, look up at the cap below; if any light is showing where the vent valve and the rubber gasket meet, you should replace the cap. Be sure to use a replacement cap that doesn't use a spring to keep air from flowing inside. For the replacement cap, choose one that has a coolant reserve/overflow system, a diaphragm spring that forms a closed seal and a rubber ring that forms a seal on the radiator filler neck's surface. The right cap on your cooling system helps the coolant go back into the radiator.

The seal on the radiator cap may be hurt by products like solvents, so clean the cap using just soap and water. With the valve facing up, place the cap at eye level and check that the valve allows air to escape; if the rubber gasket won't allow this, you should change the cap. After that, invert the cap, so it is at eye level; if any light shines through the gap between the valve and gasket, change the cap. A replacement cap ought not to have a spring holding the vent; it should support a coolant reserve/overflow system by means of a completely sealed diaphragm spring and an adjacent rubber gasket on the filler neck top surface. The correct cap will support the coolant's flow from the engine into the radiator.
