MAINTENANCE Engine Cooling Flushing the Cooling System To ensure that the coolant maintains its ability to protect the engine, the system should be completely drained every two years and a fresh 50/50 or 60/40 mixture of antifreeze and distilled water should be added. This service must be done when the engine is cold. Ask your Polaris dealer to check the coolant when he performs the fall tune-up on your snowmobile. WARNING Steam and hot liquids will cause serious burns to your skin. Never bleed the cooling system or remove the pressure cap when the engine is warm or hot. If the pressure cap needs replacement, contact your dealer for the correct part. Use of a non-standard pressure cap will not allow the recovery system to function properly. Bleeding the Cooling System CAUTION If coolant flow becomes restricted or plugged, coolant loss, air lock or engine damage may result. Most cooling systems are equipped with a filter that should be periodically inspected or replaced. If coolant becomes low in the tank, bleed the system of trapped air using the following procedure: 1. Allow the system to cool completely, then loosen the bleed screw and fill the reservoir to the FULL COLD mark. Tighten the screw. 2. Apply the parking brake and run the engine at idle RPM until the thermostat opens (5 to 8 minutes) and stays open. NOTE: As the thermostat draws in cold coolant from the heat exchangers, the cold coolant may close the thermostat. Make sure it opens and stays open. 74
