184 MAINTAINING YOUR VEHICLE Cooling System - Drain, Flush and Refill The cooling system should be drained, flushed and refilled at the intervals shown on the Maintenance Schedules. If the solution is dirty and 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. Discard old antifreeze solution according to recommended procedure. Selection Of Coolant Use only the manufacturer's recommended coolant. Refer to the Recommended Fluids, Lubricants and Genuine Parts section for the correct coolant type. CAUTION! • Mixing of coolants other than specified engine coolant, may result in engine damage, and 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 antifreeze products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator 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.
