MotoRad safety lever radiator caps 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.
MotoRad radiator caps are manufactured from high-quality components with proper relief and vacuum valves to meet all OEM specifications. These caps are quality tested to stand up to even the most demanding automotive cooling systems.
MotoRad safety lever radiator caps make an excellent replacement for worn or faulty radiator caps, which occur over time. Radiator caps are easy to install and remove because the cap’s shell turns interdependent of the sealing gasket, stem, and bottom plate.
MotoRad radiator pressure caps are 100% tested to ensure the highest quality and longevity.
