COOLING SYSTEM
Liquid 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 the break-in period.
Overheating of engine could occur if air is not fully
purged from system.
Polaris Premium 60/40 is already premixed and ready to
use. Do not dilute with water.
Coolant Level Inspection
The recovery bottle, located on the left side of the
machine, must be maintained between the minimum and
maximum levels indicated on the recovery bottle.
With the engine at operating temperature, the coolant
level should be between the upper and lower marks on
the coolant reservoir. If not:
1. Remove reservoir cap. Inner splash cap vent hole
must be clear and open.
2. Fill reservoir to upper mark with Polaris Premium 60/
40 Anti Freeze / Coolant or 50/50 or 60/40 mixture of
antifreeze and distilled water as required for freeze
protection in your area.
3. Reinstall cap.
NOTE: If overheating is evident, allow system to
cool completely and check coolant level in the
radiator and inspect for signs of trapped air in
system.
Radiator Coolant Level
WARNING
Never remove the radiator pressure cap when the
engine is warm or hot. Escaping steam and fluid can
cause severe burns. The engine must be allowed to
cool before removing the pressure cap.
NOTE: This procedure is only required if the cooling
system has been drained for maintenance and/or
repair. However, if the recovery bottle has run dry, or
if overheating is evident, the level in the radiator
should be inspected via the radiator cap first and
coolant added if necessary.
Use of a non-standard pressure cap will not allow
the recovery system to function properly.
To Access the Radiator Pressure Cap:
1. Open the front rack storage area.
2. Remove the (4) T-25 screws securing the access
cover to the front cab as shown below.
