Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Worn Belts

Tools Required: Socket set, belt tensioner tool
Check the condition of the serpentine belt and timing belt for cracks or wear.
If damaged, remove the old belt by loosening the tensioner and sliding it off the pulleys.
Install the new belt, ensuring it is properly aligned with all pulleys.
Re-tighten the tensioner to the manufacturer's specifications.

3. Check and Replace Tires

Tools Required: Tire pressure gauge, floor jack, lug wrench
Inspect all tires for signs of wear and overheating (bubbles, cracks).
If tires are worn, replace them with the correct size and type for the vehicle.
Make sure to properly inflate the new tires to the recommended PSI.

4. Inspect and Repair Brake Components

Tools Required: Jack, jack stands, lug wrench, brake tool
Remove the wheel to access the brake components.
Inspect brake pads for thickness; replace if less than 3mm.
Check calipers for proper operation and any signs of dragging.
Lubricate caliper slides and ensure proper installation.

5. Address Exhaust System Issues

Tools Required: Wrench set, exhaust pipe cutter (if needed)
Inspect the exhaust system for any areas that may be touching hot engine components.
If any part is damaged or misaligned, repair or replace it as necessary.
Ensure there are no leaks in the exhaust system.
