Operation CHARM: Car repair manuals for everyone.

General Safety Guidelines


- Block the drive wheels, as a safety routine, before beginning any service with the vehicle on the ground.

- Never work under a vehicle supported only by a jack. Use jackstands, on a flat and level hard surface, for safe support.

- Always wear appropriate eye protection.

- Use caution when working near the catalytic converter to prevent the possibility of burns. The temperatures within the converter can exceed 1200°F.
