Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical issues during repair.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Remove the Power Steering Pump

Tools Required: Socket set, wrench set, power steering fluid container
Drain the power steering fluid by loosening the return line connected to the pump and directing the fluid into the container.
Disconnect the electrical connector from the power steering pump.
Remove the mounting bolts securing the pump to the engine bracket using the socket set.
Carefully pull the pump away from the mounting bracket and disconnect any hoses still attached.

3. Inspect and Replace Components

Inspect the power steering pump for damage; if leaking, replace it with a new pump.
Check the condition of the O-rings and seals; if worn or damaged, replace them.
Inspect the hoses for cracks or leaks; replace any faulty hoses.

4. Install the New Power Steering Pump

Position the new pump in place and connect the hoses securely.
Reinstall the mounting bolts and tighten them to the manufacturer's specifications (usually around 25-30 Nm, but refer to service manual).
Reconnect the electrical connector to the pump.

5. Refill and Test the System

Refill the power steering reservoir with the appropriate fluid type specified for the vehicle (usually G002000 or equivalent).
Start the engine and allow it to run for a few minutes while turning the steering wheel left and right to bleed air from the system.
Check for leaks around the pump and hoses during the test.
