Radiator Cap
Mitsubishi FUSO®

The Radiator Cap, also known as the pressure cap, is a component of a truck's cooling system that is responsible for maintaining the proper pressure within the radiator. The cap sits on top of the radiator and seals it shut to prevent coolant from leaking out. It features a spring-loaded valve that opens at a specific pressure to release excess pressure from the system into the overflow tank. This helps to prevent damage to the engine by maintaining a consistent pressure and preventing overheating. The MC432142 Radiator Cap is designed specifically for use in certain truck models and should be replaced if it becomes worn or damaged to ensure proper function of the cooling system.
