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 153 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.
Use of a non-standard pressure cap will not allow the recovery system to
function properly. If the pressure cap needs replacement, contact your
dealer for the correct part.

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 at
the “COLD FILL” mark on the cool-
ant tank (when the engine is cold).
WARNING
Steam and hot liquids will cause serious burns to your skin. Never remove
the pressure cap when the engine is warm or hot.
CAUTION
Operating the snowmobile with insufficient coolant will result in overheating
and serious engine damage. Always maintain the coolant level as recom-
mended.
