Coolant Reservoir: Description and Operation
Operation
GAS ENGINE
The system works in conjunction with the cooling system pressure cap to utilize thermal expansion and contraction of the coolant to keep the coolant free
of trapped air. The system provides space for expansion and contraction. Also, the system provides a convenient and safe method for checking and
adjusting the coolant level at atmospheric pressure without removing the pressure cap. It also provides some reserve coolant to compensate for minor
leaks and evaporation or boiling losses.
