Is it possible for carbon monoxide to leak into a car's interior?

Question

If yes, where would it be coming from and how could you tell?

Answer 1

Yes. It would come in, most likely, closest to the source. The trunk, for example.

CO is odorless, although you might smell other items from combustion. If not, you'd notice when you started to feel sleepy or sick.

In a well kept car, this is not a problem. The exhaust is directed BEHIND the car. Fresh air is also set to come in (which may also bring in the CO) and stale air out (which takes it out.

Answer 4

Yes this is a possibility. Most likely it will leaking exhaust through your exhaust system....not necessarily at the end. Some time you do get a leak right at the exhaust manifold through the exhaust flanges which are located right in the front of the vehicle. They will and can be problematic if you have worn motor mounts. If the flanges are leaking it will be real easy to enter into the vehicle and you might never notice it. Some symptoms are dizziness, eye irritation, nausia and so on.....best thing to do is have a qualified mechanic inspect your exhaust system up front around the engine compartment...or you can go to a parts store and purchase that little gadget that looks like a stestascope but is made to find exhaust leaks. You put them on your ears like the doctor and move the rod/rube along side the exhaust system to hear any exhaust leaks. Make sure to take your time and be care not to get too close the any belts or hot exhaust components. Good Luck.

Answer 5

CO can be introduced into your car interior from any exhaust leak in your system. CO is colorless, tasteless and odorless although you can smell many of the other exhaust by-products. Symptoms of CO exposure include sleepiness, headache and dizziness - breathing CO over an extended period can even be fatal.

There is a cheap CO detector that you can purchase from any aviation supply house, pilot supply store or small airport FBO's. It is a small cardboard strip with a patch that turns black when exposed to Carbon Monoxide. It's cheap insurance and a dependable detector.

Answer 6

In the old days, (50's 60's 70's) it was more of a problem because cars were not sealed that well, especially the ones with rusted floors and trunks and doors.

Modern cars have MUCH better weather seals and MUCH better exhaust systems that don't rust out so quickly.

If your car is 10 years old or less, don't worry about it. Always keep the ventilation system running at a comfortable temp in the Flowthru mode. NOT recirculate, and fresh air will always be cycled in.

Answer 7

A well maintained, late model engine should output hardly any CO at all. That's the point of all those smog control and fuel management devices. Stochiometric + complete burning = no CO.

However exhaust has been known to have all sorts of toxins, especially if the engine is "off" in any way... so yes - if you think you have a leaky exhaust system, take it to a garage and get it fixed!

There aren't that many places CO could come from, just the exhaust manifold, header pipes, cat, and exhaust. Maybe a leaky EGR that was spewing exhaust underhood.

Answer 8

yes it could if you have a exhaust leak carbon dioxide could be getting inside the cabin of your car how ever its odorless you could obtain head aches or if the car wasn't moving how ever running you could be over exposed an even pass out an even die from carbon dioxide asphyxiation something cheap you could try is go to the store an buy a carbon dioxide detector not a smoke alarm start the car leave it idling an leave the windows up an make sure you are outside an check it periodically to see if the alarm is going off if so bring it to a garage an have it tested for your own safety PS be safe friend

Answer 9

Yes. It would come from a leaky exhaust and gaps in the body of the car. You would have mild carbon monoxide systems, such as dizziness, headaches, etc after driving.

You can test using a gas sensor.

I have been thinking this might make a good product.

yes, very possible, and extremely deadly for you, PLEASE, FOR YOUR SAFETY get that exhaust leak fixed. carbon monoxide is olderless and colorless, But if you are getting a whiff of exhaust fumes on a regular basis, your leak is in a DEADLY SPOT. and its cummulative, it can kill you after you have already left your car, carbon monoxide blocks the red blood cells ability to absorb oxygen, your face takes on a reddish glow, but its false in the sense it starves your body of needed oxygen. Symproms include extreme sleepyness, overtied , lethargic, confusion. For the sake of your future children and brain damage, always promptly fix exhaust leaks, so this stuff does not leak into the passenger compartment of the car (there is a reason exhaust pipes are vented to the rear of a vehicle.
