Cooling System
Coolant
The coolant supplied in the system at the factory is a 50/50 mixture of
ethylene-glycol and distilled water, which will provide adequate freeze
protection under most conditions. If the vehicle will be stored or oper-
ated at extremely low temperatures, greater protection may be required.
Please see your Polaris dealer.
When adding or changing coolant, Polaris recommends using 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 114 for Polaris products.
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 Level
The engine coolant level is controlled by the recovery system. The
recovery system components are:
• Coolant bottle or overflow tank
• Engine 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.
