General Maintenance
Coolant High Temperature Indicator Light
The high temperature indicator light is controlled by a switch in the
engine cooling system on liquid cooled models. If the engine coolant
reaches a certain temperature, the switch completes a circuit that turns
the light on. If you must drive your machine after the high temperature
indicator light has come on, drive slowly and stop frequently to allow
the engine to cool down. See your dealer.

Coolant Level
The engine coolant level is controlled by the recovery system. The
recovery system components are:
• Coolant bottle or overflow tank
• Engine filler neck
• Pressure cap (on some models)
• Connecting hoses
Always maintain the coolant level between the minimum and maximum
marks on the coolant bottle (when engine is cold) to prevent overheating
and serious engine damage.
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.
CAUTION
Operating the snowmobile with insufficient coolant will result in overheating
and serious engine damage. Always maintain the coolant level as recom-
mended.
