Cooling System Radiator Coolant MAINTENANCE 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. 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. 1. Open the front storage box cover. 2. Remove the pressure cap. 3. Using a funnel, slowly add coolant through the radiator filler neck. 4. Reinstall the pressure cap. 5. 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. 85
