Cooling System
Radiator and Cooling Fan
Always check and clean the screen and radiator fins at the intervals
outlined in the Periodic Maintenance Chart beginning on page 83. 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
consequent engine damage.
NOTICE: Washing the vehicle with a high-pressure hose could damage the
radiator fins and impair the radiator's effectiveness. Using a high-
pressure system is not recommended.
Radiator Coolant Level
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.
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.
1. Remove the hood. See page 27.
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: 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.
