Tools Required:
- Socket set
- Torque wrench
- Fluid catch pan
- Wrenches
- Power steering fluid
Sub-steps:
- Remove the drive belt from the power steering pump by loosening the tensioner.
- Disconnect the power steering lines from the pump using appropriate wrenches; be cautious of fluid spills.
- Unbolt the power steering pump from its mounting bracket (note bolt locations for reinstallation).
- Install the new pump by reversing the removal steps, ensuring all bolts are torqued to the manufacturer's specifications.
- Reconnect the power steering lines and ensure they are tightened properly.
- Reinstall the drive belt, ensuring proper tension.

4. Fill System with New Fluid

Fill the power steering reservoir with new fluid.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.

5. Check for Leaks

Inspect all connections and areas around the pump for any signs of leaking fluid after the system has been filled and the engine is running.
