Radiator Caps


About Radiator Caps

Your radiator cap will help keep fluid inside your radiator and, because it is by design the pressure release for the radiator, it also regulates what pressure your radiator can build internally. Heated coolant expands and thus creates pressure. Inside the radiator cap is a valve that will open when pressure reaches the caps threshold to allow coolant into the reservoir. Then, as the engine cools, the cap valve will allow the coolant to flow back into the radiator. This means proper engine cooling requires a proper radiator cap. Don’t let a broken or damaged cap compromise your radiator’s ability to properly cool your engine block. Instead, be safe with top-quality, name-brand radiator caps like Gates, Koyo, Skunk2, and Mishimoto available right here at ValiantsRacing.com.
