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
bottle, past the pressure cap, and into the radiator.
Some coolant level drop on new vehicles is normal as
the system is purging itself of trapped air. Observe
coolant level often during break-in period.
CAUTION
Overheating of engine could occur if air is not fully
purged from system.
Polaris recommends the use of Polaris 50/50 Extended
Life Antifreeze or a 50/50 mixture of high quality
aluminum compatible anti-freeze/coolant and distilled
water.
Polaris 50/50 Extended Life Antifreeze is already
premixed and ready to use. Do not dilute with water.

COOLANT LEVEL INSPECTION

q
The recovery bottle and radiator pressure cap
located under the hood.
With the engine at operating temperature, the coolant
level should be between the "MAX" and "MIN" marks on
the recovery bottle. If not, perform the following:
1. Position the vehicle on a level surface.
2. The coolant level must be maintained between the
"MAX" and "MIN" levels indicated on the recovery
bottle
3. If the coolant level is below the "MIN" mark, open the
hood to access the radiator pressure cap and
recovery bottle cap.
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.
