Cooling System
Coolant High Temperature Indicator Light
The high temperature indicator light will illuminate when engine
coolant temperature becomes too hot for safe continued operation of
the engine. If you must drive your snowmobile after the high
temperature indicator light has come on, drive slowly and stop
frequently to allow the engine to cool down. Driving in deep snow will
also help cool the engine. See your dealer for service. Add coolant if
the level is low.
NOTE: Engine performance will be reduced if you continue operating
when the high temperature light is on.
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. Have your
Polaris dealer perform this service.
Bleeding the Cooling System
Bleed the cooling system at the intervals outlined in the Periodic
Maintenance Table beginning on page 88. In addition, bleed the
cooling system any time one or more of the following conditions exist.
S
A component of the cooling system has been serviced or replaced
(including coolers, radiator, engine, coolant lines and oil cooler)
S
A cooling system failure occurs, resulting in coolant loss
S
A coolant line has been disconnected for any reason
S
A coolant leak occurs
