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.
