206 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. The first change should not be required until 5 years or 100,000 miles (160,000 km), whichever comes first. The coolant should be flushed and changed every two years or 36,000 miles (57,600 km) thereafter. 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. Used automotive antifreeze is a recyclable commodity. Discard or recycle as facilities exist in your area. Selection Of Coolant Use only the manufacturer's recommended coolant, refer to Recommended Fluids, Lubricants and Genuine Parts for correct coolant type. CAUTION! Failure to use the proper antifreeze could cause radiator plugging and engine overheating. Do not mix antifreeze brands or 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 or heater core. Adding Coolant When adding coolant, a solution of 50% ethylene glycol antifreeze coolant in distilled water should be used. Use higher concentrations (not to exceed 60%) if temperatures below -32°F (-35°C) are anticipated. Please note that it is the owner's responsibility to maintain the proper level of protection against freezing according to the temperatures occurring in the area where the vehicle is operated.
