MAINTAINING YOUR VEHICLE 321 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 recovery bottle provides a quick visual method for determining that the coolant level is adequate. With the engine cold, the level of the coolant in the coolant recovery bottle should be between the "MAX" and "MIN" marks. The radiator normally remains completely full, so there is no need to remove the radiator cap except for checking coolant freeze point or replacement with new antifreeze coolant. Your service attendant should be advised of this. So long as the engine operating temperature is satisfactory, the coolant recovery bottle need only be checked once a month. When additional coolant is needed to maintain the proper level, it should be added to the coolant recovery bottle. Do not overfill. 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 water 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 recovery bottle. 7
