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 133 for the part numbers of
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.
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.
n Coolant Level
The engine coolant level is controlled
by the recovery system. The recovery
system components are:
S
Coolant bottle or overflow tank
S
Filler neck
S
Pressure cap
S
Connecting hoses
Always maintain the coolant level at the
“COLD FILL” line (A) on the coolant tank
(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.
