Remove the cap and check the fluid level against the dipstick.
If low, top off with recommended power steering fluid (check owner's manual for specifications).

3. Inspect and Replace Power Steering Pump

Remove the Drive Belt:
- Use a socket set to loosen the tensioner and remove the drive belt from the power steering pump.
Disconnect Power Steering Lines:
- Use an appropriate line wrench to disconnect the high-pressure and return lines from the pump.
Remove the Power Steering Pump:
- Unbolt the pump from its mounting bracket (typically requires a socket set).
- Carefully lift the pump out of its location.
Install New Power Steering Pump:
- Position the new pump in place and secure it with bolts to the mounting bracket. Torque to manufacturer's specifications (refer to service manual).
Reconnect Power Steering Lines:
- Reconnect the high-pressure and return lines, ensuring they are tightened properly to avoid leaks.

4. Reinstall Drive Belt

Route the drive belt back around the power steering pump and other pulleys.
Use the tensioner to apply tension and secure the belt in place.

5. Refill and Bleed Power Steering System

Refill the power steering fluid reservoir to the proper level.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid level again and top off if necessary.
