MAINTENANCE
Cooling System
Flushing the Cooling System
To ensure that the coolant maintains its ability to protect the engine,
drain the system completely every five (5) years and add a fresh mixture
of antifreeze and distilled water. This service must be performed when
the engine is cold. Ask your POLARIS dealer to check the coolant when
he performs the fall tune-up on your snowmobile.
Bleeding the Cooling System
CAUTION! Steam and hot liquids will cause burns to your skin. Never bleed the
cooling system or remove the pressure cap when the engine is warm or hot.
Use of a non-standard pressure cap will not allow the recovery system to
function properly. If the pressure cap needs replacement, contact your
dealer for the correct part.
NOTICE: Severe engine damage may occur if the cooling system becomes
restricted or plugged or contains trapped air pockets.
Perform this procedure in a well-ventilated area. Use the recommended
coolant. See page 115.
1. Open the side panels and remove the hood.
2. Close the side panels.
WARNING! Never operate a snowmobile with the side panels open or removed.
3. Position the snowmobile with the right ski and control arms
elevated at a 45-degree angle.
4. Fill the coolant bottle to the
COLD FILL mark.
5. Using an 8 mm wrench,
loosen the air bleed screw
located on the top of the
coolant outlet elbow. Use a
shop towel to catch any
coolant that leaks from the
bleeder. Tighten the screw
after a steady stream of
coolant flows from the
bleeder.
