Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the battery to avoid electrical shorts while working.

2. Inspect and Repair Engine Components

Check Engine Oil:
- Remove the dipstick, wipe it clean, reinsert it, and check the oil level.
- If low, top up with the manufacturer-recommended oil type.
- If burnt, consider an oil change.
Inspect Drive Belts and Hoses:
- Visually check belts for cracks or signs of wear.
- Replace any belts that show damage.
- Inspect hoses for leaks or cracks; replace as necessary.

3. Brake System Inspection

Remove Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the wheel to access the brake components.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if worn down.
- Inspect rotors for glazing or overheating signs; resurfacing may be required.

4. Transmission Fluid Change (if applicable)

Drain and Replace Fluid:
- Locate the transmission fluid pan, remove the drain plug, and drain the fluid.
- Refill with the proper type and amount of transmission fluid per the manufacturer’s specifications.
