Solution

1. Preparation

Gather Tools and Parts: Collect an OBD-II scanner, socket set, torque wrench, brake pad replacement kit (if necessary), and a coolant flush kit (if necessary).
Safety Precautions: Ensure the vehicle is parked on a flat surface, turn off the engine, and let it cool down before inspection.

2. Inspect and Replace Damaged Belts or Hoses

Inspect: Check all belts (serpentine belt, timing belt) and hoses for any signs of melting or damage.
Replace: If any belts or hoses are damaged:
- Loosen the tensioner and remove the old belt.
- Install the new belt according to the routing diagram.
- Replace any damaged hoses by loosening the clamps and removing them; install new hoses and secure with clamps.

3. Brake Inspection and Replacement

Inspect: Check the brake pads and rotors for signs of overheating or wear.
Replace: If brake pads are worn or damaged:
- Remove the wheel using a socket set.
- Unbolt the caliper and hang it securely, avoiding strain on the brake line.
- Remove old pads and install new ones; ensure they are seated properly.
- Reattach the caliper and wheel, torquing the lug nuts to manufacturer specifications.

4. Transmission Fluid Service

Inspect Fluid: Check the transmission fluid level and color; burnt fluid will have a dark color and burnt smell.
Change Fluid: If fluid is burnt:
- Drain the old transmission fluid using a wrench to remove the drain plug.
- Replace the filter (if applicable), and install a new one.
- Refill with fresh transmission fluid according to the manufacturer’s specifications.
