MAINTENANCE AND LUBRICATION
Engine Cooling System
How it Works
The overflow bottle is
located in front of the right
front tire of the machine.
It must be maintained
between the minimum and
maximum levels indicated
on the overflow bottle.
The engine coolant level is
controlled or maintained
by the recovery system.
The recovery system
components are the
overflow 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 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.
NOTE: Some coolant level drop on new machines is normal as the
system is purging itself of trapped air. Observe coolant levels and
maintain as recommended by adding coolant to the overflow bottle.
