Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, stable surface.
Disconnect the battery for safety.

2. Identify the Leak Source

Inspect Reservoir: Remove the cap and check for damage.
Examine Hoses: Follow hoses from reservoir to pump and rack for leaks.
Check Pump and Rack: Look for wet areas or drips on the pump or steering rack.

3. Replace Damaged Components

If Reservoir is Damaged:
- Remove the reservoir by disconnecting the hoses and mounting bolts.
- Install the new reservoir, ensuring tight connections.
If Hoses are Leaking:
- Use a socket set to disconnect the leaking hose.
- Replace with a new hose and secure it properly.
If Power Steering Pump is Faulty:
- Disconnect the pump from the hose connections and mounting bolts.
- Replace the pump with a new unit and reattach all connections.
If Steering Rack is Leaking:
- Remove the tie rod ends and disconnect the steering linkage.
- Unbolt the steering rack and replace it with a new one, ensuring proper alignment.

4. Refill and Bleed the System

Refill the power steering reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid levels again and top off as necessary.
