Tools Required: Socket set, torque wrench, wrench set, fluid catch pan.
Locate the power steering pump in the engine compartment.
Remove the drive belt by releasing tension using a belt tensioner tool.
Disconnect the power steering fluid hoses from the pump using a wrench, allowing fluid to drain into the catch pan.
Unbolt the power steering pump from its mounting bracket (typically 3-4 bolts).
Carefully remove the pump from its position.

3. Inspect and Replace

Check the old power steering pump for damage and ensure it is the source of the leak.
If the pump is damaged, replace it with a new unit.
Install new O-rings on the fluid hose connections if applicable to prevent future leaks.

4. Install the New Power Steering Pump

Position the new power steering pump in place.
Bolt the pump securely to the mounting bracket using the torque specifications found in the service manual.
Reconnect the power steering hoses, ensuring they are tightened properly to avoid leaks.
Reinstall the drive belt around the pump and ensure proper tension.

5. Fill and Bleed the Power Steering System

Reconnect the negative battery terminal.
Fill the power steering reservoir with the appropriate type of power steering fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check the fluid level and add more if necessary.
