LIQUID COOLING SYSTEM
Cooling System Overview
The engine coolant level is maintained by the recovery
system.The recovery system components are the recovery
bottle, radiator 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 recovery 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 machines is normal as
the system is purging itself of trapped air. Observe
coolant levels often during the break–in period.
