Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts while working.

2. Inspect and Replace Worn Belts

Tools Required: Socket set, belt tensioner tool.
Sub-steps:
1. Remove the engine cover, if applicable, to access the belts.
2. Check the serpentine belt and accessory belts for cracks, fraying, or glazing.
3. If damaged, remove the old belt using the belt tensioner tool to relieve tension.
4. Install the new belt according to the routing diagram (usually found on a sticker in the engine bay).
5. Recheck the tension and ensure it is properly aligned.

3. Inspect and Repair Brake System

Tools Required: Jack and jack stands, lug wrench, brake cleaner, caliper tool.
Sub-steps:
1. Safely lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the brake components.
3. Check the brake calipers for signs of sticking or overheating; inspect the brake pads for uneven wear.
4. If necessary, replace the brake pads or calipers and ensure they slide freely.
5. Reassemble the brake system and wheels.

4. Check Tire Condition

Tools Required: Tire pressure gauge, tread depth gauge.
Sub-steps:
1. Inspect all tires for any signs of uneven wear or damage.
2. Measure the tire tread depth; replace tires that are worn below the manufacturer's minimum depth.
3. Ensure tires are properly inflated according to the recommended pressure.
