Cooling System
Coolant High Temperature Indicator Light
The high temperature indicator light will illuminate when engine cool-
ant 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.
TIP: 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,
drain the system completely every two years and add a fresh mixture of
antifreeze and distilled water. This service must be performed 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
CAUTION! Steam and hot liquids will cause burns to your skin. Never bleed
the cooling system or remove the pressure cap when the engine is warm or hot.
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.
NOTICE: If coolant flow becomes restricted or plugged, coolant loss, air lock or
engine damage may result. Most cooling systems are equipped with
a filter that should be periodically inspected or replaced.
