Solution

1. Preparation

Gather all necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Collect Fluid Sample

Tools Required: Clean container, turkey baster or fluid siphon.
Use the turkey baster or fluid siphon to extract a small amount of power steering fluid from the reservoir.
Place the fluid sample in a clean, clear container for examination.

3. Inspect Fluid Sample

Visual Examination: Check the fluid for cloudiness, discoloration (e.g., brown or milky appearance), or floating debris.
Odor Assessment: Smell the fluid to detect any burnt odor indicative of overheating.

4. Replace Contaminated Fluid

Tools Required: Socket set, fluid catch pan, funnel.
If contamination is confirmed, drain the old power steering fluid using a fluid catch pan.
Remove the drain plug if applicable, or disconnect the return line to drain the fluid.
Refill the system with new, manufacturer-recommended power steering fluid through the reservoir.
