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 Pre-
mium 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 100 for POLARIS products.
NOTICE: 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
• Engine filler neck
• Pressure cap
• Connecting hoses
Always maintain the coolant level at the “full cold” line on the coolant
bottle when the engine is cold.
NOTICE: Operating the snowmobile with insufficient coolant will result in over-
heating and serious engine damage. Always maintain the coolant
level as recommended.
