306 MAINTAINING YOUR VEHICLE Disposal of Used Engine Coolant 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. To prevent ingestion by animals or children do not store ethylene glycol based engine coolant in open containers or allow it to remain in puddles on the ground. If ingested by a child, contact a physician immediately. Clean up any ground spills immediately. Coolant Level The coolant bottle provides a quick visual method for determining that the coolant level is adequate. With the engine off and cold, the coolant level should be between the ranges indicated on the bottle. Some darkening of the coolant bottle will occur over time. This is normal. When additional coolant is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill. See your authorized dealer to properly fill the cooling system. Points to Remember NOTE: When the vehicle is stopped after a few miles of operation, you may observe vapor coming from the front of the engine compartment. This is normally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vaporized when the thermostat opens, allowing hot coolant to enter the radiator. If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate. • Do not overfill the coolant bottle. • Check coolant freeze point in the system. • If frequent coolant additions are required, the cooling system should be pressure tested for leaks. • Maintain coolant concentration at 50% ethylene glycol antifreeze (minimum) in water for proper corrosion protection of your engine which contains aluminum components.
