Coolant Reservoir: Description and Operation
Operation
Non-Pressure System
NON-PRESSURE SYSTEM
This system works in conjunction with the pressure cap to utilize thermal expansion and contraction of the coolant to keep the coolant free of trapped air.
It provides a volume for expansion and contraction, provides a convenient and safe method for checking coolant level, and adjusting level at atmospheric
pressure without removing the pressure cap. It also provides some reserve coolant to cover minor leaks and evaporation or boiling losses.

PRESSURE SYSTEM
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.
