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.
NOTE: 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.
Surge Tank Cap
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.
Surge Tank
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.
