Cooling System

Coolant

POLARIS recommends the use of POLARIS Antifreeze 50/50 Premix. This antifreeze is already premixed and ready to use. Do not dilute with water. If the vehicle will be stored or operated at extremely low temperatures, greater protection may be required. An authorized dealer can assist.
To ensure that the coolant maintains its ability to protect the engine, we recommend that the system be completely drained every five (5) years and fresh Antifreeze 50/50 Premix.
Any time the cooling system has been drained for maintenance or repair, replace the coolant with fresh Antifreeze 50/50 Premix.
NOTICE
If coolant flow becomes restricted or plugged, coolant loss, air lock, or engine damage may result. Most cooling systems are equipped with a filter that should be periodically inspected or replaced.

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. Add coolant as needed.
NOTICE
Operating the snowmobile with insufficient coolant will result in overheating and serious engine damage. Always maintain the coolant level as recommended.

Bleeding the Cooling System

caution
Steam and hot liquids will cause burns to your skin. Never bleed the cooling system or remove the pressure cap when the engine is warm or hot.
Use of a non-standard pressure cap will not allow the recovery system to function properly. If the pressure cap needs replacement, your dealer can provide the correct part.
NOTICE
If the coolant flow becomes restricted or plugged, coolant loss, air lock or engine damage may result.
  1. Position the vehicle so that the top of the tunnel is level. Elevate the front of the vehicle slightly if necessary.
  2. Make sure the engine is cold before continuing.
  3. Remove the right side panel.
  4. Fill the coolant bottle with properly mixed coolant to the maximum mark. Do not install the pressure cap at this time.
  5. Remove the bleed screw from the water outlet manifold and/or the thermostat housing. Allow the coolant to bleed through the system until it runs out the bleed holes. Reinstall the bleed screw into the manifold.
  6. Add coolant to the coolant bottle to the maximum mark.
  7. Reinstall the side panel. Always ensure that the hood and side panels are securely in place before starting the engine.
  8. Start the engine and run at a fast idle for two to three minutes. Loosen the bleed screw occasionally to purge any trapped air.
  9. Stop the engine and check the coolant bottle level. Add coolant as needed. Reinstall the side panel.
  10. Carefully and briefly touch the top of the tunnel cooler under the seat. If the system is bled properly, the cooler will be warm to the touch. If not, repeat step 8. Lift the front of the snowmobile slightly to assist in the bleeding.
  11. Remove the side panel. Reinstall the pressure cap. Reinstall the side panel.
  12. Carefully lower the front end of the snowmobile.
