MAINTENANCE Cooling System Radiator Coolant 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 added. Any time the cooling system has been drained for maintenance or repair, replace the coolant with fresh Antifreeze 50/50 Premix. If the recovery bottle has run dry, check the level in the radiator. Add coolant as needed. CAUTION! Escaping steam can cause 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 box cover. 2. Remove the access panel screws. Squeeze the outer edges of the panel inward to remove the panel. 3. Remove the pressure cap. 4. Using a funnel, slowly add coolant through the Radiator Cap radiator filler neck. 5. Reinstall the pressure cap. Use of a non-standard pressure cap will not allow the recovery system to function properly. Your POLARIS dealer can provide the correct replacement part. 6. Reinstall the access panel and secure the front box cover. 109
