Solution

1. Preparation

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

2. Inspect and Replace Damaged Belts and Hoses

Tools Required: Socket set, belt tensioner tool, pliers
Sub-steps:
1. Visually inspect all belts (serpentine belt, timing belt) and hoses for cracks, fraying, or signs of burning.
2. If damage is found, remove the affected belt(s) using the belt tensioner tool to relieve tension.
3. Replace with OEM or quality aftermarket parts, ensuring proper fit and tension.
4. Reconnect battery and start the engine to test for the smell.

3. Check and Replace Transmission Fluid

Tools Required: Torque wrench, fluid pump, catch pan
Sub-steps:
1. Locate the transmission dipstick or fill plug and check the fluid level.
2. If the fluid appears burnt (dark brown or has a burnt smell), drain the fluid using a catch pan.
3. Replace with the recommended transmission fluid (check owner’s manual for specifications).
4. Use a fluid pump to refill to the correct level, ensuring it is not overfilled.
5. Recheck for the burning smell during test drive.

4. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, lug wrench, brake cleaner
Sub-steps:
1. Safely lift the vehicle using jacks and secure with jack stands.
2. Remove the wheels using a lug wrench to access the brakes.
3. Inspect brake pads and rotors for excessive wear and replace as necessary.
4. Clean components with brake cleaner before reassembling.
5. Reinstall wheels and lower the vehicle.
