⚠️ Safety Warnings

Important safety information - read before proceeding

•Allow the engine to cool before working on hot components.
•Disconnect the battery to prevent electrical shorts.
•Use jack stands to secure the vehicle; never rely on a jack alone.

Symptoms

•Burning smell noticeable from the engine bay
•Smoke or vapor visible from under the hood
•Unusual noise from the engine or wheels (e.g., grinding or squealing)
•Check engine light illuminated
•Decreased engine performance or power loss
•Fluid leaks observed under the vehicle

Diagnostic Steps

1
Inspect for fluid leaks: Check under the vehicle for any fluid puddles that could indicate oil, coolant, or brake fluid leaks.
2
Check engine temperature: Monitor the engine temperature gauge; ensure it is operating within normal limits.
3
Scan for error codes: Use an OBD-II scanner to check for any diagnostic trouble codes related to the engine or transmission.
4
Inspect belts and hoses: Visually inspect engine belts and hoses for signs of wear, cracking, or burning.
5
Examine brake components: Check brake pads and rotors for excessive wear or overheating.
6
Look for electrical issues: Inspect wiring and connectors for signs of melting or burning.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off and cooled down.
Disconnect the battery to prevent electrical shorts.

2. Fluid Leak Repair

Sub-steps:
1. Identify the source of the leak (e.g., oil pan, coolant hose).
2. Replace any damaged gaskets or hoses.
3. Refill fluids as necessary (engine oil, coolant).
Tools Required: Socket set, wrenches, fluid container.
Safety Warnings: Allow the engine to cool before working on hot components.

3. Brake Component Inspection and Replacement

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for thickness; replace if worn down to less than 3mm.
3. Check rotors for scoring; machine or replace if necessary.
4. Reassemble the wheel and perform a brake fluid flush if needed.
Tools Required: Jack and jack stands, lug wrench, brake tool set, torque wrench.
Safety Warnings: Use jack stands to secure the vehicle; never rely on a jack alone.

4. Electrical System Inspection

Sub-steps:
1. Inspect wiring harnesses for signs of damage or melting.
2. Replace any damaged wires or connectors.
3. Secure loose connections.
Tools Required: Multimeter, wire strippers/crimpers.
Safety Warnings: Disconnect the battery before working on electrical systems.
