Hummer Radiator Cap

Hummer is a U.S. vehicle brand of GM. As Hummer's R&D and experimental teams are in the U.S., the quality of its products can keep unchanged. During the development of Hummer, many popular radiator cap parts have been built. The radiator cap helps as a pressure relief valve and will avoid excess pressure. A properly functioning radiator cap is the best option to provide security over the engine coolant.

Although Hummer has lots of auto parts with impressive performance, radiator cap parts still need repair and maintenance after a long time of usage. A radiator cap is responsible for regulating the pressure in the vehicle's cooling system. The most common radiator cap pressures include 16 PSI, 15 PSI, 13 PSI, and 10 PSI.
