Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fluids

Engine Oil:
- Remove the oil dipstick and check for burnt oil.
- If oil is burnt, drain the oil using an oil pan and replace it with the recommended oil type (e.g., 0W-20).
Coolant:
- Check the coolant reservoir and radiator for low levels.
- If low, refill with the appropriate coolant mixture (Toyota Genuine Super Long Life Coolant).

3. Inspect Components

Belt and Pulleys:
- Visually inspect serpentine belts for signs of wear or burning.
- If damaged, replace the belt using a socket set to release tension and remove the old belt.
Electrical Components:
- Inspect wiring harnesses and connectors for signs of melting or burning.
- Replace any damaged wiring using electrical tape or splicing techniques as needed.

4. Clean and Reassemble

Clear any debris from the engine bay that could be causing smells.
Reassemble all components securely and ensure that all connections are tight.
Reconnect the battery.

5. Test the Vehicle

Start the engine and allow it to idle while monitoring for any unusual smells or noises.
Take the vehicle for a short test drive to ensure that the burning smell does not reappear.
