Ways To Diagnose Car Odors
Almost all kinds of smells in your car is not a good sign, regardless of what sort of odor it is. Therefore, it is important that you can identify and understand what every odor means and how you may be able to fix them. Below are some of the most typical odors that is an indication of a car problem.
There could possibly be a leak inside your fuel supply line or vent hose. Most modern cars come with a fuel vapor recovery system, and thus there should not be any gasoline odor except when you are refilling the gas tank of your vehicle.
The Smell of Rotten Egg
It may be the odor of hydrogen sulfide and that means the catalytic converter is probably not converting the hydrogen sulfide the way it should be, in the exhaust to sulfur dioxide. It is best to bring your vehicle to a reliable technician, so they can confirm if the catalytic converter is the problem or perhaps it is a fuel problem.
Particularly while you are hitting the brakes; this smell can suggest problems in the braking system, which should be examined immediately. Some other reasons for a burning odor is a hardened drive belt, a short or overload electrical circuit, or due to a seized pulley.
Smell of Burning Oil
The seals or gaskets can get broken, cracked or damaged, and that can leak oil on the engine exhaust chamber. Although the leaks in your car may be minor, you should not take it for granted. Regularly inspect the coolant recovery tank and oil dipstick of your car. In case you are losing coolant or oil, most likely you will find a leak there.
This is because your cabin air conditioning filter could be clogged and dirty. If you leave it unattended, the cabin air filter will get clogged, making the A/C compressor and blower motor burn out in the long run. Change your cabin air filter at least every 30,000 miles, or check the manual of your car for guidelines.
Smell of Dead Animal
Rodents are actually drawn from the heat of a car engine. Apart from being extremely destructive, they create a foul odor when these animals die inside your vehicle.
