Engine Cooling
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 r eady 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 Coo lan t Level
Maintain the coolant level at the “full cold” line on the coolant bottle
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 some models)
S Connecting hoses
