MAINTENANCE Coolant Mixture General Maintenance The coolant supplied in the system is a 50/50 mixture of ethylene-glycol and distilled water. This mixture provides protection against freezing at temperatures to -34° F (-37° C). If greater protection is required, the percentage of antifreeze to water may be increased. Use Premium 60/40 anti-freeze coolant, which is already premixed and ready to use. Do not dilute with water. Never exceed a 60% antifreeze/40% water mixture. Contact you dealer if greater protection is required. NOTE: Never add tap water to the cooling system. Minerals cause deposits and may react adversely with the metals in the engine and cooling system. 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. n Coolant Level The coolant level in the coolant bottle must be maintained at the recommended level shown on the coolant bottle to prevent overheating and serious engine damage. The level on some models must be maintained between the minimum and maximum marks. Other models require the coolant level to be maintained at the "full cold" line when the engine is cold. CAUTION Operating the snowmobile with insufficient coolant will result in overheating and serious engine damage. Always maintain the coolant level as recommended. The engine coolant level is controlled by the recovery system. The recovery system components are: S Coolant bottle or overflow tank S Engine filler neck S Pressure cap (on applicable models) S Connecting hoses 98
