Chevy Impala Radiator Caps

A radiator cap is an important part of your Chevy Impala’s engine cooling system that may seem to be plain in its design and performed functions. Apart from sealing the system and providing simple access for coolant refill, a radiator cap works as an emergency pressure release valve that comes into action during the engine overheat and saves the cooling system from damage. When the pressure reaches a certain level, the cap opens its valve letting a portion of coolant to escape.

Depending on the system architecture, the cap can be installed either directly above the radiator or on the coolant tank. In both cases, it carries out the same functions but achieves the desired result in slightly different ways. It goes without saying that for proper function of your engine cooling system, the radiator cap must be in fully operational condition.
