MAINTENANCE
Cooling System
Radiator Coolant
To ensure that the coolant maintains its ability to protect the engine,
Polaris recommends that you drain the system completely every two
years and add a fresh mixture of antifreeze and water.
Replace the coolant any time the cooling system has been drained for
maintenance or repair. If the recovery bottle has run dry, check the level
in the radiator. Add coolant as needed.
1. Open the front box cover
and pull open the access
door.
2. Remove the pressure cap.
3. Using a funnel, slowly add
coolant through the radia-
tor filler neck.
4. Reinstall the pressure cap.
5. Secure the access door.
6. Secure the box cover.
NOTE: Use of a non-standard pressure cap will not allow the recovery system
to function properly. Contact your dealer for the correct replacement
part.
WARNING
Escaping steam can cause severe burns. Never remove the pressure cap
while the engine is warm or hot. Always allow the engine to cool before
removing the pressure cap.
