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, 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.
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.
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
Operating the snowmobile with insufficient coolant will result in
overheating and serious engine damage. Always maintain the
coolant level as recommended.
