Install the new power steering pump in reverse order of removal.
Torque the bolts to the manufacturer's specifications (consult service manual for exact values).
Reconnect the power steering lines and ensure all connections are tight.

4. Inspect and Repair Steering Gear (if necessary)

If the pump replacement did not resolve the issue, examine the steering gear.
Remove any protective covers to access the steering gear.
Check for leaks or damaged seals; replace if necessary.
Lubricate any moving parts and ensure everything operates smoothly.

5. Final Assembly and Testing

Reinstall the serpentine belt, ensuring proper alignment.
Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.
