MAINTENANCE
Cooling System
Coolant
The coolant supplied in the system is a 60/40 mixture of ethylene-glycol
and distilled water. This mixture provides protection against freezing.
Contact your dealer if greater protection is required.
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. See page 112 for the part numbers of Polaris prod-
ucts.
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.
n
Coolant Level
The engine coolant level is controlled by the recovery system. The
recovery system components are:
• Coolant bottle or overflow tank
• Filler neck
• Pressure cap
• Connecting hoses
Always maintain the coolant level between the minimum and maximum
marks on the coolant bottle (when engine is cold) to prevent overheating
and serious engine damage.
CAUTION
Operating the snowmobile with insufficient coolant will result in overheating
and serious engine damage. Always maintain the coolant level as recom-
mended.
