Cooling System: Service Precautions

ENVIRONMENTAL AND SAFETY CONCERNS

Environmental Concerns
- Used engine coolant is a controlled waste and should be disposed of properly.
- Used engine coolant contains trace amounts lead and other heavy metals which are extremely hazardous to humans and wild life.
- Do not pour used coolant into storm drains or sewers.
- Do not mix used coolant with liquid hazardous wastes, such as used engine oil, transmission fluid, or brake fluid. Many waste disposal facilities will not accept used coolant when mixed with other wastes.

Safety Concerns
- Never remove a radiator cap while the cooling system is hot. An overheated cooling system can store a tremendous amount of pressure and heat.




- To prevent serious personal injury, always verify that the upper radiator hose is cool and depressurized prior to removing the radiator cap.
