Solution

1. Preparation

Tools Required: Socket set, screwdrivers, fluid catch pan, UV light (if using dye), rags, safety goggles, gloves.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool and disconnect the battery for safety.

2. Identify and Repair the Leak

Power Steering Fluid Reservoir:
- Remove the cap and check for cracks or damage.
- If damaged, replace the reservoir with a new part.
Power Steering Pump:
- Remove the belt from the power steering pump.
- Disconnect the hoses from the pump.
- Replace any worn seals or the pump itself if leaks are detected.
Hoses Inspection:
- Inspect the high-pressure hose and return line for cracks or leaks.
- Replace any damaged hoses using a socket set to disconnect and reconnect them.
Steering Rack:
- If the leak is traced to the steering rack, inspect the seals.
- If leaking, either replace the rack or reseal it, depending on the condition.

3. Refill and Bleed System

After repairs, refill the power steering fluid reservoir with the manufacturer-recommended fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check the fluid level again and add more if necessary.
