Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and parked safely.
Disconnect the battery to prevent electrical shorts.

2. Check Fluid Level

Remove the power steering reservoir cap and wipe the dipstick clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, top off with the manufacturer-recommended power steering fluid.

3. Inspect for Leaks

Visually inspect all hoses and connections for signs of fluid leaks.
If leaks are found, replace the affected hoses or seals.
Clean any spilled fluid to identify new leaks during testing.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering lines from the pump.
Unbolt the power steering pump from its mounting bracket.
Install the new pump and reattach the lines, ensuring a secure fit.
Reinstall the serpentine belt according to the routing diagram.

5. Bleed the Power Steering System

Fill the power steering reservoir with new fluid.
Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check the fluid level and add more if necessary.
Recheck for leaks during the bleeding process.
