Cooling System
The engine coolant level is controlled or maintained by the recovery
system. The recovery system components are the overflow bottle, radia-
tor filler neck, radiator pressure cap and connecting hose.
As coolant operating temperature increases, the expanding (heated)
excess coolant is forced out of the radiator, past the pressure cap, and
into the overflow bottle. As engine coolant temperature decreases, the
contracting (cooled) coolant is drawn back up from the tank, past the
pressure cap, and into the radiator.
Some coolant level drop on new vehicles is normal as the system is
purging itself of trapped air. Observe coolant levels and maintain as rec-
ommended by adding coolant to the overflow bottle.
