COOLING SYSTEM

COOLING SYSTEM OVERVIEW COOLANT LEVEL INSPECTION
The engine coolant level is controlled, or maintained, by The pressure cap q and recovery bottle w are located
the recovery system. The recovery system components under the front hood of the vehicle. The coolant level
are the recovery bottle, radiator filler neck, radiator must be maintained between the minimum and
pressure cap and connecting hose. maximum levels indicated on the recovery bottle. 2
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.

NOTICE
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.
Polaris Premium 50/50 Antifreeze is premixed and
ready to use. Do not dilute with water.
With the engine at operating temperature, the coolant
level should be between the upper and lower marks on
the coolant recovery bottle. If not, perform the following

hydrometer.
2. Remove the front hood.
3. View the coolant level in the recovery bottle.
4. If the coolant level is below the MIN line, inspect the
coolant level in the radiator.
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.

WARNING
Never remove the pressure cap when the engine is
warm or hot. Escaping steam can cause severe burns.
The engine must be cool before removing the pressure
cap.
• A 50/50 mixture of antifreeze and distilled water will
provide the optimum cooling, corrosion protection, and
antifreeze protection. 5. Remove the pressure cap. Using a funnel, add
coolant to the top of the filler neck.
• Do not use tap water, straight antifreeze or straight
water in the system. Tap water contains minerals and 6. Reinstall the pressure cap.
