‘Odors are definitely evidence of something wrong. Here are six vehicle warning smells:
- Burnt Rubber
This smell could mean slipping drive belts or misplaced loose hoses that might be rubbing against rotating accessory drive pulleys.
Caution: Do not reach in if engine is hot.
- Hot Oil
This smell could mean that oil is leaking onto the exhaust system.
Caution: Turn of the engine before checking for the leak.
This smell is likely the sign of a possible gas leak, a fuel injector line, the fuel tank, or a bad gas cap.
Caution: Any smell of fuel is a possible hazard, so immediate attention should be given.
- Sweet Syrup
This smell might be a sign that the car is leaking engine coolant from a component related to the car’s cooling system.
Caution: Do not open the radiator cap when it is hot.
- Burning Carpet
This smell could be the sign of brake trouble. Have your brakes checked right away, especially if this smell is happening during normal driving conditions.
Caution: Brake trouble is a serious safety hazard.
- Rotten Eggs
This smell could mean that the catalytic converter is not converting hydrogen sulfide in the exhaust to sulfur dioxide properly.
Caution: A poor running engine can cause the catalytic converter to become overloaded and fail due to meltdown.
