MAINTENANCE General Maintenance Coolant Mixture 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. 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. 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: DCoolant tank or overflow tank DEngine filler neck DPressure cap (on some models) DConnecting hoses CAUTION The coolant level in the reservoir or surge tank must be maintained between the minimum and maximum levels to prevent overheating and serious engine damage. Some models require the coolant level be maintained at the "full cold" line on the coolant tank when the engine is cold. 120
