⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow engine to cool before opening the hood or working on the cooling system.

Symptoms

•Burning smell noticeable after driving
•Smoke coming from under the hood or near wheels
•Engine overheating (check temperature gauge)
•Warning lights illuminated on the dashboard (e.g., oil pressure, temperature)
•Reduced braking performance (if related to brakes)
•Oil spots or leaks under the vehicle

Diagnostic Steps

1
Inspect the engine bay for any signs of oil leaks or burnt oil residue.
2
Check the temperature gauge to determine if the engine is overheating.
3
Use an OBD-II scanner to check for any stored error codes related to the engine or transmission.
4
Inspect brake components for excessive wear or overheating (look for discoloration on brake pads or rotors).
5
Check the condition of engine oil and coolant levels for any signs of contamination or depletion.
6
Inspect belts and hoses for signs of wear or damage that could lead to overheating.

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working.

2. Addressing Oil Leaks

Clean the engine bay using appropriate engine cleaner to identify the source of the leak.

- Tools: Socket set, torque wrench.
- Parts: New gaskets/seals as needed.
- Safety Warning: Allow engine to cool before cleaning to avoid burns.

3. Fixing Overheating Issues

Check the coolant level and top up with the correct coolant type if low.
Inspect the radiator for blockages or leaks.
Replace the thermostat if it is not opening properly (check for temperature fluctuations).
- Tools: Socket set, screwdriver set.
- Parts: New thermostat and coolant.

4. Brake Inspection and Repair

Remove the wheel to access brake components.
Inspect brake pads and rotors for excessive wear; replace if necessary.
- Tools: Jack and jack stands, lug wrench.
- Parts: New brake pads and rotors if worn.

5. Final Assembly

Reassemble any components removed during the repair process.
Reconnect the battery and start the vehicle to check for any leaks or abnormal smells.
