Have you ever noticed an usual car smell? Vehicles use various fluids, and when something goes wrong, an odd smell may become apparent. Bad car smells can indicate a mechanical problem and, if neglected, can lead to expensive repairs. If you need help sniffing out the odd scent coming from the vehicle, below is a list of common smells and what they could mean.
Sweet syrup smell
Coolant as an active ingredient called ethylene glycol. If you notice a sweet syrup smell, this can signal there’s a coolant leak in the heating system or radiator.
A burning smell can indicate that one of your rubber hoses has deteriorated or become loose. A loose hose can burn due to moving across hot engine parts. Additionally, if oil leaks on hot engine parts, a strong burning smell may be noticeable.
A musty smell usually comes from the A/C vents due to excess moisture accumulating in the air vents. Excess moisture causes mold and mildew build up in the system and causes a musty odor.
Rotten egg smells can signal a bad catalytic converter or a malfunctioning fuel system. Hydrogen sulfide is present in gasoline. If there’s a break in the converter, the sulfur smell can’t be transformed into its odorless form. The hydrogen sulfide will emit a noticeable rotten egg smell.
If you recently fueled up, the smell of gas can linger for a bit. Check your clothing or shoes to ensure you didn’t accidentally drop a bit. If the smell lasts longer an hour, it may indicate a leaky fuel tank, injector, or a broken gas cap. It’s best to have your vehicle inspected to root out the cause of the odor.
