MAINTAINING YOUR VEHICLE 449 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. 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 and children. If ingested by a child, contact a physician immediately. Clean up any ground spills immediately. Coolant Pressure Cap The coolant pressure cap must be fully tightened to prevent the loss of coolant and to insure that the coolant will return to the radiator from the coolant bottle. The pressure cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces. WARNING! The warning words "DO NOT OPEN HOT" on the radiator pressure cap are a safety precaution. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pressure cap. Hoses And Vacuum/Vapor Harnesses Inspect surfaces of hoses and nylon tubing for evidence of heat and mechanical damage. Hard or soft spots, brittle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration of the rubber. Pay particular attention to those hoses nearest to high heat sources such as the exhaust manifold. Inspect hose routing to be sure hoses do not come in contact with any heat source or moving component which may cause heat damage or mechanical wear. 7
