Solution

1. Preparation

Gather all necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Tools Required: Power steering fluid, funnel, turkey baster or fluid siphon, clean rags, gloves.

2. Drain Old Fluid

Using a funnel, refill the power steering reservoir with fresh, manufacturer-recommended power steering fluid.
Check the fluid level and add more if necessary.

4. Bleed the System

Start the engine and turn the steering wheel from lock to lock (full left to full right) several times to help remove air bubbles from the system.
Check the fluid level again and top off if necessary.
