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 116 for POLARIS products.
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/overflow tank
• Pressure cap
• Connecting hoses
Always maintain the coolant level at or
slightly above the FULL COLD mark on
the coolant bottle (when the engine is
cold).
1. Stop the engine.
2. Open the right side panel.
3. View the coolant level in the coolant
bottle.
4. Add coolant as needed.
NOTICE:
Operating the snowmobile with insufficient coolant will result in over-
heating and serious engine damage. Always maintain the coolant
level as recommended.
