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 98. 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
1. Read the entire coolant bleed procedure before beginning. After
beginning the bleed procedure, do not stop the engine until reaching
step 14.
2. Move the snowmobile into a well-ventilated area. Allow the engine
to cool completely.
