1. The smell
of burnt rubber could be slipping drive
belts or misplaced loose
hoses that might be rubbing against rotating accessory drive
pulleys. Do not reach in if the engine compartment is hot.
2. The smell
of hot oil could mean that oil is leaking onto the
system. To verify the leak, look for oil on the pavement or
smoke coming from the engine area.
3. The smell
of gasoline is likely the sign of a gas leak in some area of the
vehicle such as a fuel injector line or the fuel tank. Any smell
of fuel can result in a possible fire hazard, so immediate
attention should be given.
4. The sweet
smell of syrup may be a sign that your car is leaking
coolant from a leaky component related to the carís
system. Do not open the radiator cap when it is hot.
5. The smell
of burning carpet could be a sign of brake trouble and a safety
hazard. Have your brakes checked right away, especially if this
smell is happening during normal driving conditions.
6. The smell
of rotten eggs is never a good one and, if you smell it coming
from your vehicle, it could mean a problem with your
converter not converting the hydrogen sulfide in the exhaust to
sulfur dioxide properly. This smell can also be attributed to a
poor running engine, causing the catalytic converter to become
overloaded and fail due to meltdown.
