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.
Bleeding the Cooling System
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.
Recovery System Models
If the coolant level becomes low in the
recovery tank, bleed the system of any trapped
air. Visually inspect the coolant filter (B) and
replace it if it’s dirty.
1 F ill the recovery tank with coolant to the
maximum indicated mark.
2 Elevate the front end of the machine slightly
to aid bleeding of the heat exchangers.
3 With pressure cap removed, add coolant and
fill to the top of the filler neck.
4 Install the pressure cap with the lever lock up, in its release position.
5 Run the engine at various RPMs for two to three minutes to purge the
system of trapped air.
6 C lose the lever lock and check the recovery tank fluid level.
Steam and hot liquids burn. Never bleed the cooling system
or remove the pressure cap when the engine is warm or hot.
Serious per sonal injury could result.
