Use a socket set to remove the belt tensioner and release tension on the serpentine belt.
Remove the old serpentine belt, inspecting for cracks or wear.
Install the new serpentine belt according to the routing diagram located on the engine cover.
Reapply tension using the belt tensioner and check for proper alignment.

4. Inspect and Replace Power Steering Pump (if necessary)

Remove any covers obstructing access to the power steering pump.
Disconnect the power steering hoses using a wrench and capture any leaking fluid.
Unbolt the power steering pump from its mounting bracket.
Install the new power steering pump, securing it with the bolts to the specified torque.
Reconnect the hoses and refill the power steering fluid.

5. Check Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack and tie rods for any visible wear or play.
Replace any damaged components as necessary, following the manufacturer's specifications for installation.
