Coolant Reservoir: Description and Operation
Operation
OPERATION
The coolant recovery container works in conjunction with the radiator pressure cap. It utilizes thermal expansion and contraction of coolant to keep
coolant free of trapped air. It provides a volume for expansion and contraction of coolant. It also provides a convenient and safe method for checking
coolant level and adjusting 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 will then be drawn from the coolant tank and
returned to a proper level in the radiator.
