Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues during repair.

2. Replace Power Steering Fluid

Tools Required: Fluid pump, clean funnel.
Remove the power steering fluid reservoir cap.
Use a fluid pump to extract old fluid from the reservoir.
Fill with new power steering fluid that meets OEM specifications (typically ATF or specific PS fluid).
Reinstall the reservoir cap securely.

3. Inspect and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, wrench set, fluid catch pan.
Remove any components obstructing access to the power steering pump (e.g., air intake duct).
Disconnect the power steering hoses from the pump using a wrench, and capture any leaking fluid in a catch pan.
Unbolt the power steering pump from its mounting bracket and remove it from the engine bay.
Install the new power steering pump in reverse order, ensuring all bolts are torqued to manufacturer specifications.
Reattach the power steering hoses and ensure they are tight and leak-free.

4. Check and Replace Serpentine Belt (if worn)

Tools Required: Belt tensioner tool or ratchet.
Inspect the serpentine belt for cracks, fraying, or signs of wear.
If replacement is needed, release tension from the belt using the tensioner tool.
Remove the old belt and install the new one, following the routing diagram usually found on a sticker under the hood.

5. Final Steps

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock to purge air from the system.
Recheck the fluid level and top off if necessary.
