Engine Cooling System

Coolant Level

The recovery bottle (1) is located on the
left side of the machine. To access the
recovery bottle, remove the left side panel
as outlined on page 81.
Maintain the coolant level between the
minimum and maximum marks on the
bottle (when the fluid is cool). Add
coolant as needed.

Cooling System Operation

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