272 MAINTAINING YOUR VEHICLE Cooling System - Drain, Flush and Refill At the intervals shown on the Maintenance Schedules, the system should be drained, flushed and refilled. If the solution is dirty or contains a considerable amount of sediment, clean and flush with a reliable cooling system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals. Properly dispose of old antifreeze solution. Selection Of Coolant Use only the manufacturer's recommended coolant, refer to Fluids, Lubricants and Genuine Parts for correct coolant type. CAUTION! Mixing of coolants other than specified HOAT engine coolants, may result in engine damage and may decrease corrosion protection. If a non-HOAT coolant is introduced into the cooling system in an emergency, it should be replaced with the specified coolant as soon as possible. Do not use plain water alone or alcohol base engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator engine coolant and may plug the radiator. This vehicle has not been designed for use with Propylene Glycol based coolants. Use of Propylene Glycol based coolants is not recommended.
