COOLANT LEVEL INSPECTION
The coolant tank is located on the front-right side of the
cargo box, under the coolant bottle access panel. The
coolant level should be filled to the FULL COLD level
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.
6. If coolant was required, start engine and check for
leaks. Make sure radiator fins are clean to prevent
overheating.

using a commercially available pressure tester. The
pressure cap relief pressure is 18 psi. Replace the
cap if it does not meet this specification.
Never remove pressure cap when engine is warm or
hot. The cooling system is under pressure and serious
burns may result. Allow the engine to cool before
3. To test the cooling system, connect the pressure
tester to the cooling neck
4. The system must maintain 10 psi for five minutes or
longer. If pressure loss is evident within five minutes,
check the filler neck, radiator, hoses, clamps and
water pump weep hole for leakage.
