Solution

1. Preparation

Tools Needed: Safety gloves, safety goggles, flashlight, jack and jack stands, socket set, OBD-II scanner.
Safety Warning: Disconnect the battery before starting any electrical inspection to avoid shocks.

2. Addressing Overheating Components

Brake System:
1. Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
2. Remove the Wheel: Take off the wheel on the side where the burning smell is strongest.
3. Inspect Brake Components: Examine brake pads and rotors for signs of excessive heat or wear.
4. Replace as Necessary: If the brake pads are worn down or the rotor is damaged, replace them with new parts according to manufacturer specifications.
Engine Components:
1. Open the Hood: Ensure the engine is cool before proceeding.
2. Inspect Wiring and Connectors: Look for any damaged or burnt wires and replace them.
3. Check Belts and Hoses: Replace any worn or frayed belts and hoses using appropriate replacements.

3. Fluid Replacement

Check and Replace Fluids: If oil, coolant, or transmission fluid levels are low, top them off or replace them if contaminated.
Flush Systems if Necessary: If coolant is low or contaminated, perform a coolant flush to prevent overheating.
