MAINTENANCE Cooling System The engine coolant level is controlled, or maintained, by the recovery system. The recovery system components are the recovery bottle, the radiator filler neck, the radiator pressure cap and the connecting hose. As coolant operating temperature increases, the expanding (heated) excess coolant is forced out of the engine, past the pressure cap, and into the recovery bottle. As engine coolant temperature decreases the contracting (cooled) coolant is drawn back up from the bottle, past the pressure cap, and into the radiator. NOTE: Some coolant level drop on new vehicles is normal as the system is purging itself of trapped air. Check the coolant level and maintain as recommended by adding coolant to the recovery bottle. Polaris recommends the use of Polaris Premium 60/40 anti-freeze/coolant or a 50/50 mixture of high quality aluminum compatible anti-freeze/ coolant and distilled water. Polaris Premium 60/40 is already premixed and ready to use. Do not dilute with water. See page 121 for the part numbers of Polaris products. NOTE: Always follow the manufacturer's mixing recommendations for the freeze protection required in your area. Recovery Bottle Coolant The recovery bottle is located under the front storage box cover near the radiator cap. Maintain the coolant level between the minimum and maximum marks on the bottle (when the fluid is cool). 1. Position the vehicle on a level surface. 2. Open the front storage box cover. 3. View the coolant level. 4. Add coolant as needed. 84
