Coolant Recovery System

DESCRIPTION







The coolant reserve/overflow system 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.

OPERATION
As the engine cools, a vacuum is formed in the cooling system. This vacuum will draw coolant out of the coolant reservoir and into the radiator.
