Solution

1. Preparation

Gather tools and parts required for the job.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure electrical safety.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Remove the power steering fluid reservoir cap.
2. If the fluid is dark or contaminated, use a syringe to extract old fluid from the reservoir.
3. Refill the reservoir with the recommended Toyota power steering fluid (typically ATF fluid).
4. Start the engine and turn the steering wheel from lock to lock several times to circulate the new fluid.

3. Inspect and Replace Power Steering Pump

Sub-steps:
1. Remove the serpentine belt using a socket and ratchet to relieve tension.
2. Disconnect power steering lines from the pump using a wrench; be cautious of fluid spillage.
3. Remove the mounting bolts for the power steering pump.
4. Install the new power steering pump by reversing the removal steps.
5. Torque the mounting bolts to manufacturer's specifications (usually around 15-25 ft-lbs).
6. Reconnect power steering lines and ensure no leaks.

4. Inspect and Replace Serpentine Belt

Sub-steps:
1. Inspect the serpentine belt for cracks, fraying, or wear.
2. If necessary, remove the belt using the same method as in the power steering pump replacement.
3. Install a new serpentine belt following the routing diagram typically found on a sticker in the engine bay.
4. Ensure that the belt is properly seated on all pulleys.
