Operation

COOLANT RECOVERY CONTAINER

The coolant recovery container works in conjunction with the radiator pressure cap. It utilizes thermal expansion and contraction of the coolant to keep the coolant free of trapped air. It provides a volume for expansion and contraction of the coolant. It also provides a convenient and safe method for checking the coolant level and adjusting the level at atmospheric pressure. This is done without removing the radiator pressure cap. The system also provides some reserve coolant to the radiator to cover minor leaks and evaporation or boiling losses.

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