MAINTAINING YOUR VEHICLE 211 Check the front of the radiator and condenser for any accumulation of bugs, leaves, etc. Clean the radiator and condenser by gently spraying water from a garden hose at the back of the core. Check the engine cooling system hoses for condition and tightness of connection. Inspect the entire system for leaks. Any hoses that show cuts or severe abrasion must be replaced. Cooling System - Drain, Flush and Refill At the intervals shown on the Maintenance Schedule (5 years/100,000 miles), the system should be drained, flushed and refilled. 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. Engine Coolant Disposal Used ethylene glycol based engine coolant is a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. Do not store ethylene glycol based engine coolant in open containers or allow it to remain in puddles on the ground. Prevent ingestion by animals or children. If ingested by a child, contact a physician immediately. 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! Failure to use the proper antifreeze could cause radiator plugging and engine overheating. Do not mix antifreeze brands or types. 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. Adding Coolant When adding coolant, a minimum solution of 50% ethylene glycol antifreeze coolant in water should be used. 7
