Solution

1. Preparation

Tools Required: Socket set, fluid catch pan, funnel.
Park the vehicle on a level surface and turn off the engine. Allow the engine to cool down.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the recommended power steering fluid (Toyota Genuine ATF WS).
Start the engine and turn the steering wheel from lock to lock several times to help purge any air from the system. Recheck the fluid level and top off if necessary.

3. Inspect for Leaks

Visually inspect the power steering pump, hoses, and connections for any signs of leaks.
If leaks are detected, follow these sub-steps:
- 3.1. Tighten Loose Connections: Use a socket set to tighten any loose hose clamps.
- 3.2. Replace Damaged Hoses: If hoses are cracked or worn, replace them with OEM parts. Remove the old hose and install the new one, ensuring a secure fit.

4. Replace the Power Steering Pump (if necessary)

If the pump is confirmed to be faulty:
- 4.1. Remove the Old Pump:
  - Disconnect the battery to prevent electrical shorts.
  - Remove the serpentine belt using a belt tensioner tool.
  - Disconnect the power steering lines from the pump using a wrench.
  - Remove the mounting bolts securing the pump to the engine and take out the pump.
- 4.2. Install the New Pump:
  - Position the new pump in place and secure it with the mounting bolts (torque to manufacturer specifications).
  - Reconnect the power steering lines and ensure they are tight.
  - Reinstall the serpentine belt, ensuring proper routing.

5. Final Check

Reconnect the battery.
Start the engine and check for leaks.
Turn the steering wheel from lock to lock to ensure the pump is functioning properly and listen for any unusual noises.
