Solution

1. Preparation

Gather tools: socket set, torque wrench, belt tension gauge, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect and Replace the Serpentine Belt

Sub-steps:
1. Open the hood and locate the serpentine belt routing diagram (usually found on a sticker near the engine).
2. Use a socket wrench to relieve tension on the belt tensioner and remove the old belt.
3. Inspect the tensioner for any signs of wear; replace if necessary.
4. Install the new serpentine belt according to the routing diagram.
5. Reapply tension to the tensioner and ensure the belt is seated properly.

3. Check and Replace Brake Pads (if necessary)

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for thickness; replace if they are less than 3mm.
3. Remove the caliper bolts, slide the caliper off, and replace the pads.
4. Reinstall the caliper and wheel, tightening bolts to the manufacturer’s torque specifications.

4. Inspect Power Steering System

Sub-steps:
1. Locate the power steering fluid reservoir and check the fluid level.
2. If low, top off with the recommended power steering fluid.
3. Inspect hoses for leaks or cracks and replace any damaged hoses.

5. Check Wheel Bearings and Suspension

Sub-steps:
1. Lift the vehicle safely using a jack and secure with jack stands.
2. Spin the wheels by hand, listening for any grinding or squealing noises.
3. Inspect suspension components for visible wear and replace as necessary.
