Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Power Steering Fluid Check

Tools Required: None
Remove the power steering fluid reservoir cap.
Check the fluid level; if low, add the appropriate type of power steering fluid (consult the owner's manual for specifications).
If the fluid is dark or contaminated, proceed to replace it.

3. Inspect and Replace Power Steering Pump

Tools Required: Socket set, wrench set, fluid catch pan
Disconnect the negative battery terminal to ensure safety.
Remove the serpentine belt by releasing tension on the belt tensioner and sliding the belt off the power steering pump pulley.
Disconnect the power steering lines from the pump and allow any remaining fluid to drain into the catch pan.
Remove the mounting bolts securing the power steering pump and take out the pump.
Install the new power steering pump by reversing the removal steps, ensuring to torque the mounting bolts to the manufacturer's specifications.

4. Check and Replace Serpentine Belt

Tools Required: Socket set, wrench set
Inspect the serpentine belt for cracks or wear; if damaged, replace it with a new belt.
Route the new belt according to the belt routing diagram usually found on a sticker under the hood.
Reconnect the negative battery terminal.
