For:
Safety first
- Park on flat ground, set the parking brake and chock the wheels.
- Never get under a car held up only by a jack. Use jack stands.
- Let the engine and exhaust cool first.
- Disconnect the battery before unplugging electrical parts.
- Wear safety glasses.
- If something doesn't match your car, stop and ask a shop.
Follow your part's instructions and your service manual's torque specs.
