Did this guide work for you?

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.
