Unbolt the pump from its mounting bracket.
Install the new pump in reverse order, ensuring all connections are tight.
Refill the power steering fluid and bleed the system by turning the steering wheel from lock to lock several times with the engine running.

4. Inspect and Replace the Serpentine Belt

Locate the serpentine belt tensioner and use a wrench to relieve tension.
Remove the serpentine belt and inspect for cracks or wear.
Install a new serpentine belt, ensuring it is routed correctly over all pulleys.
Reapply tension according to manufacturer specifications.

5. Inspect and Replace Steering Components

If the steering rack or tie rod ends are worn, remove the damaged components.
Replace with new parts and ensure all bolts are torqued to manufacturer specifications.
Reinstall any components removed during the inspection process.
