Solution

1. Preparation

Tools Required: Socket set, screwdrivers, jack and jack stands, safety goggles, gloves.
Safety Warnings: Allow the engine to cool before starting work; disconnect the battery if working on electrical components.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Remove any covers obstructing access to the drive belts.
2. Inspect the belts for cracks, fraying, or signs of wear.
3. If damaged, note the belt part numbers and proceed to remove the old belts by loosening the tensioner pulleys.
4. Install new belts, ensuring proper routing according to the vehicle's belt diagram.
5. Re-tighten the tensioners to the manufacturer's specifications.

3. Brake Inspection and Replacement

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for wear; replace if they are below the minimum thickness.
4. Check rotors for signs of overheating or warping and replace if necessary.
5. Reassemble the brake components and wheel, ensuring all bolts are torqued to specifications.

4. Address Fluid Leaks

Sub-steps:
1. Identify any leaking fluids (brake fluid, oil, coolant) by checking under the vehicle and around components.
2. Replace any faulty hoses or gaskets that are leaking.
3. Clean any spilled fluids to prevent further burning smells.
