Disconnect the battery to ensure safety while working on electrical components.

2. Fluid Replacement

Tools Required: Fluid pump, funnel, catch pan.
Locate the power steering fluid reservoir and remove the cap.
Use a fluid pump to extract old power steering fluid from the reservoir.
Refill with the manufacturer-recommended power steering fluid (consult the owner’s manual for specifications).

3. Replace Power Steering Pump (if needed)

Tools Required: Socket set, torque wrench, belt tensioner tool.
Remove the drive belt from the power steering pump by using a belt tensioner tool to relieve tension.
Disconnect the power steering fluid lines from the pump; use a catch pan to avoid spills.
Unbolt the power steering pump from its mounting bracket and remove it.
Install the new power steering pump in reverse order, ensuring all connections are secure.
Reattach the drive belt and ensure it is properly tensioned (refer to torque specifications).

4. Bleed the Power Steering System

Tools Required: Funnel, power steering fluid.
Fill the power steering reservoir with fluid to the recommended level.
Start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.
Check fluid levels and top off as necessary.
