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 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:
D
Coolant tank or overflow tank
D
Engine filler neck
D
Pressure cap (on some models)
D
Connecting hoses
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.
