Collection: Radiator Caps
Radiator caps play a crucial role in maintaining the cooling system's efficiency & preventing overheating. They serve as a seal to the radiator, maintaining the appropriate pressure inside the cooling system. The radiator cap is designed with a spring-loaded valve that allows excess pressure to escape when the coolant reaches its boiling point. This prevents coolant from boiling over & maintains the system's optimal operating temperature. Additionally, the radiator cap acts as a vacuum valve, allowing coolant to be drawn back into the radiator as the engine cools down. This ensures that the radiator remains filled with coolant & prevents air pockets from forming in the system. It is important to use the correct radiator cap specified by the vehicle manufacturer to maintain proper pressure levels & ensure a tight seal. Regular inspection & replacement of the radiator cap, as recommended by the manufacturer, is essential for the proper functioning of the cooling system.
