If your radiator is leaking fluid, overflowing or the radiator hose collapses, your truck's radiator cap could be at fault. A radiator cap with a bad seal will also allow air into the system, creating air pockets that can result in engine overheating. Replace your malfunctioning radiator cap with this quality replacement that will install in seconds.

Prevent dangerous scalding situations with these unique radiator caps which utilize a lever that locks the cap to the filler neck, requiring the lever be lifted before removal. When the lever is lifted, the valve pressurizing in the cooling system is opened and pressure is vented through the overflow tube, making it safe to remove the radiator cap.
