Cooling System
Overflow Bottle Coolant Level
Always check and change the coolant at the intervals outlined in the Periodic Maintenance
Chart beginning on page 65. 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. Place the transmission in PARK.
3. Remove the hood. See page 26.
4. View the coolant level in the
overflow bottle.
5. If the coolant level is below the
safe operating range, 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/Changing Procedure
1. Remove the hood. See page 26.
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.
