DESCRIPTION
The system works along with the radiator pressure cap. This is done by using thermal expansion and contraction of the coolant to keep the coolant free of trapped air. It provides:
The coolant reserve/overflow system consists of a radiator mounted pressurized cap, a plastic reserve/ overflow tank (Fig. 3) (Fig. 4), a tube (hose) connecting the radiator and tank, and an overflow tube on the side of the tank.

OPERATION
As the engine cools, a vacuum is formed in the cooling system of both the radiator and engine. Coolant will then be drawn from the coolant tank and returned to a proper level in the radiator.
