- Remove the drive belt from the power steering pump pulley.
Remove Power Steering Pump:
- Disconnect fluid lines from the pump using a wrench; be prepared for fluid spillage.
- Unbolt the power steering pump from its mount using a socket set.
- Carefully remove the pump from the engine bay.
Install New Power Steering Pump:
- Position the new pump in place and secure it with bolts, tightening to the manufacturer’s torque specifications.
- Reconnect the fluid lines, ensuring they are tight to prevent leaks.

4. Reinstall Drive Belt

Place the drive belt back onto the power steering pump pulley.
Use the wrench to reposition the tensioner and ensure proper tension on the belt.

5. Bleed Power Steering System

Fill the power steering reservoir to the proper level if not already done.
Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check fluid level again and top off if necessary.
