Cooling System MAINTENANCE 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, 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. 87
