The coolant in your car is highly toxic, but the ethylene glycol smells sugary sweet. The fix could be as easy as tightening a loose radiator cap or replacing a hose.

2. Something’s Burning

One of the bad flywheel symptoms is a weird burning smell inside your car. This smell is present because your gears are slipping. Your clutch can’t work properly, and that lets the gears slip.

To make this smell go away, you’ll have to replace your clutch and flywheel.

3. Rotten Eggs

You may already know that sulfur creates a rotten egg smell, but did you know that smell can come from your car? There are trace amounts of sulfur in gasoline.

As your car runs, your catalytic converter turns foul-smelling hydrogen sulfide into not smelly sulfur dioxide. When your converter fails, the smell remains, and you’ll need to get it replaced.

4. Gasoline

The only time you should smell gas is while you’re filling up your car. If you smell gasoline during any other time, you could have a leak.

The first place to look is at your fuel tank vent hose or fuel injection line. This is a smell you should never ignore as gasoline is highly flammable.

5. Gym Locker

Do you have a sour gross smell that reminds you of a gym locker? Then it’s probably your AC unit. This gross smell is the same because it’s a similar problem in each situation.

There’s mold present, and it’s thriving. If it’s in your AC vents, you can try running air through the system when the AC is off. This will dry out the system and kill the mold.

If this doesn’t solve the problem, you’ll need to bring your car to a professional for cleaning.

6. Burning Carpet

If you smell burning carpet while you’re driving, it’s a sign that your brake pads are overheating. You need your brake pads to effectively stop your car.

If it’s stressful driving conditions, this is normal. But if you aren’t traversing steep mountain passes, then overheating brake pads are a problem.

The best way to resolve this problem is to bring your car in for the professionals to look at. There are several reasons your brakes could be overheating.
