Radiator Caps are designed to seal the top of the radiator filler neck to prevent coolant loss, pressurise the cooling system and raise the boiling point of the coolant. They are manufactured with a metal or plastic design depending on the vehicle manufacturer’s specifications.

The most important component of a coolant module is the cooling radiator. The radiator is the main heat exchanger located at the front of the engine, or if air conditioning is mounted, behind the condenser. It transfers the heat ejected by the engine to the ambient air through the coolant. The main function of the radiator is to redistribute heat created by the engine so that it doesn't seize up or overheat. This is achieved primarily through the radiator's design. The radiator is folded much like an accordion bellows, giving it a great deal of surface area.
