Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems
•Allow the engine to cool before opening the hood or handling any components

Symptoms

•Burning smell (could be oil, rubber, or electrical)
•Smoke from under the hood
•Engine overheating warning light illuminated
•Unusual noises from the engine compartment
•Loss of power or acceleration issues

Diagnostic Steps

1
Inspect for leaks by checking under the vehicle and around the engine for fluid leaks (oil, coolant, transmission fluid)
2
Check engine temperature by monitoring the engine temperature gauge for any signs of overheating
3
Scan for error codes using an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to engine performance or overheating
4
Perform a visual inspection of belts, hoses, and electrical wiring for signs of wear, fraying, or damage that could cause burning smells
5
Inspect engine oil by checking the engine oil level and condition; burnt oil can emit a burning smell
6
Examine brake components to ensure they are not excessively worn, which could cause a burning smell if overheated
