MAINTENANCE

Cooling System

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 mix-
ture of antifreeze and distilled water should be added. Have your
POLARIS dealer perform this service.

Bleeding the Cooling System

Bleed the cooling system at the intervals outlined in the Periodic Main-
tenance Table beginning on page 82. In addition, bleed the cooling sys-
tem any time one or more of the following conditions exist.

• A component of the cooling system has been serviced or replaced

(including coolers, radiator, engine, coolant lines and oil cooler)

• A cooling system failure occurs, resulting in coolant loss

• A coolant line has been disconnected for any reason

• A coolant leak occurs

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.

1. Read and understand the entire coolant bleed procedure before

beginning. Do not start the engine until instructed to do so.

2. Move the snowmobile into a well-ventilated area. Allow the engine

to cool completely.

3. Place the transmission in neutral.

4. Raise and support the front of the snowmobile so the front bumper

is at least 30 inches (76 cm) from the ground.
