COOLING SYSTEM
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.
Recommended Coolant:
Polaris 50/50 Extended Life Anti-freeze
2880514 (quart)
2880513 (gallon)
COOLANT LEVEL INSPECTION
The coolant tank is located on the front-left side of the
cargo box, under the coolant bottle access panel. The
coolant level should be filled to the FULL COLD level
q
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 tank. If not, perform the following procedure:
1. Ensure the vehicle is positioned on a level surface.
2. View the coolant level tank.
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.
3. If the coolant level is below the FULL COLD line,
inspect the vehicle for signs of leaking on the radiator,
engine, and coolant hoses.
4. Remove the pressure cap. Using a funnel, add the
recommended 50/50 coolant mixture to the FULL
COLD level on the tank.
Recommended Coolant:
Polaris 50/50 Extended Life Anti-freeze
2880514 (quart)
2880513 (gallon)
5. Reinstall the pressure cap.
NOTICE
Use of a non-standard pressure cap will not allow the
recovery system to function properly.
