Cooling System
Engine Overheating
The over-temperature indicator
on the instrument cluster will
illuminate
when the engine is
overheating. The indicator will
flash
when engine temperature
reaches critical levels.
Illuminated Indicator
Take action to cool the engine:
• Drive in loose snow.
• View the coolant level.
Do not open the pressure cap while the engine
is hot
. Add coolant if the level is low.
• Stop the engine and allow it to cool down.
If you must continue to operate while the indicator light is
illuminated
,
drive slowly and stop the engine frequently to allow it to cool down.
Flashing Indicator
If the indicator
flashes
, continued operation could result in serious
engine damage. The system will automatically reduce engine power and
create a misfire condition. Stop the engine
immediately
. Allow the
engine to cool down.
If engine overheating seems to be caused by something other than poor
cooling conditions, see your dealer for service.
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.
