Coolant Reservoir: Description and Operation
COOLANT PRESSURE CONTAINERDESCRIPTION
Fig. 5:
The coolant pressure container consists of a pressure chamber and a overflow chamber (Fig. 5). The coolant pressure container is mounted in the right side engine compartment. An overflow hose connects the pressure chamber to the overflow chamber.
NOTE: Coolant will normally be in the pressure chamber side of the coolant bottle. The overflow chamber should normally be empty
OPERATION
The pressure chamber keeps the coolant free of trapped air, provides a volume for expansion and contraction, and provides a convenient and safe method for checking and adjusting coolant level at atmospheric pressure. It also provides some reserve coolant to cover minor leaks, evaporation or boiling losses. The overflow chamber allows coolant recovery in case of an overheat.
