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 prevent electrical shocks or shorts.

2. Inspect and Repair Leaks

Tools Required: Socket set, rags, leak detection dye.
1. Check for visible leaks in hoses and connections, especially around the radiator and oil pan.
2. If leaks are found, replace damaged hoses or gaskets as needed.
3. Clean any spilled fluids with rags to prevent further burning odors.

3. Replace Burnt Electrical Components (if necessary)

Tools Required: Multimeter, electrical tape, soldering iron (if applicable).
1. Identify burnt wires or connectors using a multimeter.
2. Replace damaged connectors or wire sections.
3. Secure all connections with electrical tape or heat-shrink tubing.

4. Brake System Inspection

Tools Required: Jack, jack stands, torque wrench.
1. Lift the vehicle and remove the wheels to access the brakes.
2. Inspect brake pads and rotors for excessive wear or binding.
3. Replace pads and rotors if they are worn down or damaged.

5. Cooling System Check

Tools Required: Coolant pressure tester, funnel.
1. Inspect the radiator and cooling system for clogs or leaks.
2. If the coolant is low, top it off with the appropriate coolant type.
3. Test the cooling system with a pressure tester to find hidden leaks.
