MAINTENANCE
Cooling System
Overflow Bottle Coolant Level
Always check and change the coolant at the
intervals outlined in the Periodic
Maintenance Chart beginning on page 55.
Maintain the coolant level between the
minimum and maximum marks on the
bottle (when the fluid is cool).
1. Position the vehicle on a level surface.
2. Lift the hood. View the coolant level in
the overflow bottle.
3. If the coolant level is below the safe
operating range, lift the hood and locate
the overflow bottle lid. Remove the cap
and use a funnel to add coolant through
the filler opening. Reinstall the cap.
Tip: If coolant must be added often, or if the
overflow bottle runs completely dry, there
may be a leak in the system. Your POLARIS
dealer can inspect the cooling system.
Radiator Coolant Level
Always check and clean the screen and radiator fins at the intervals outlined in the Periodic
Maintenance Chart beginning on page 55. Do not obstruct or deflect air flow through the
radiator by installing unauthorized accessories in front of the radiator or behind the cooling
fan. Interference with the radiator air flow can lead to overheating and consequentially,
engine damage.
1. Lift the hood.
CAUTION! Escaping steam can cause burns. Never remove the pressure cap while the engine is
warm or hot. Always allow the engine to cool before removing the pressure cap.
2. Slowly remove the radiator cap.
3. View the coolant level through the opening.
4. Use a funnel and slowly add coolant as needed.
Tip: This procedure is required only if the cooling system has been drained for maintenance and/or
repair. But if the overflow bottle has run dry, the level in the radiator should also be inspected.
5. Reinstall the pressure cap. Use of a non-standard pressure cap will not allow the
recovery system to function properly. Your POLARIS dealer can provide the correct
replacement part.
