MAINTENANCE
Engine Cooling - Liquid Cooled Models
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.
If the pressure cap (A) 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.
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.
