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
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 t h e Cooling System
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.
WARNING
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.
Recovery System (WideTrak)
If the coolant level becomes low in the coolant bottle, bleed the system
of any trapped air. Visually inspect the coolant filter (A) and replace it
if it’s dirty.
1. Fill the coolant bottle with coolant to the
maximum mark.
2. Elevate the front end of the machine
slightly to aid bleeding of the heat
exchangers.
3. Remove the pressure cap and add coolant t o
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. Close the lever lock and check the coolant bottle fluid level. Add
coolant if necessary to the maximum mark.
