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.
NOTE
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.
COOLANT STRENGTH
Test the strength of the coolant using an antifreeze
hydrometer.
• A 50/50 mixture of antifreeze and distilled water will
provide the optimum cooling, corrosion protection, and
antifreeze protection.
• Do not use tap water, straight antifreeze or straight
water in the system. Tap water contains minerals and
impurities which build up in the system.
• Straight water or antifreeze may cause the system to
freeze, corrode, or overheat.

COOLANT LEVEL INSPECTION
The pressure cap
under the front hood of the vehicle. The coolant level
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 recovery bottle. If not, perform the following
procedure:
1. Position the vehicle on a level surface.
2. If the coolant level is below the MIN line, inspect the
coolant level in the radiator.
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.
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
3. Remove the pressure cap. Using a funnel, add
coolant to the top of the filler neck.
4. Reinstall the pressure cap.
Use of a non-standard pressure cap will not allow the
recovery system to function properly.
5. Remove recovery bottle cap and add coolant using a
funnel.
