COOLING SYSTEM

Cooling System Overview
The engine coolant level is controlled, or 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 break-in period.
Overheating of engine could occur if air is not fully
purged from system.

Cooling System Hoses

The high pressure inside the radiator hose can cause
coolant to leak【A】 or the hose to burst if the line is not
properly maintained. Visually inspect the hoses for signs
of deterioration. Squeeze the hoses. A hose should not
be hard and brittle, nor should it be soft or swollen.
Replace the hose if any fraying, cracks 【B】 or bulges
【C】 are noticed.
