Safety Warnings: Ensure the engine is cool before starting the inspection. Disconnect the battery if working on electrical components.

2. Identify Source of Burning Smell

Inspect Engine Compartment: Look for any oil leaks on the exhaust manifold or any burnt wires.
Check Brake Components: Inspect brake pads and rotors for excessive wear or overheating.

3. Address Fluid Issues

Change Engine Oil: If the oil is burnt or contaminated:
1. Drain the old oil using a socket set to remove the oil drain plug.
2. Replace oil filter.
3. Refill with manufacturer-recommended oil type.
Replace Transmission Fluid: If the transmission fluid appears burnt:
1. Drain the old fluid from the transmission pan.
2. Replace the filter if applicable.
3. Refill with the appropriate transmission fluid.

4. Repair Electrical Issues

Repair or Replace Damaged Wires: If any wires are burnt or damaged:
1. Remove the damaged section of wire using wire cutters.
2. Strip insulation from the ends and use wire connectors to splice in new wire.
3. Insulate connections with electrical tape or heat shrink tubing.

5. Reassemble and Test

After repairs, reassemble any components removed for access.
Reconnect the battery (if disconnected) and start the engine.
Monitor for burning smell and check for leaks or unusual noises.
