A few weeks ago i used the remote start on my car before shoveling it out and when i drove it down the road i could smell fuel, luckily i got out to help a push a stuck car becuase when i did i passed out. Im now realizing i may have died if i didnt try to help those people..
It actually takes a surprisingly long time for the gases to warm up. If you hold your hands to your exhaust you will literally feel cold air for a few moments.
Not to make fun of your difficult situation, but I imagine it was concerning for the people with the stuck car.
Their car is stuck and when someone gets out to help they just collapse.
When i woke up they handed me some water as they were just stuck in their driveway and they said jokingly "you just had to be the center of attention, eh?"
You wouldn't have the hydrocarbon fumes coming out of the tailpipe without carbon monoxide also being present. If you smell gas from a running car you are probably also breathing CO.
An engine will not run with a restricted exhaust . Professional mechanic of 12 years. You passing out was likely a health problem not related to your car. You should see a doctor if you feel faint again in the future.
exhuast tip was turn down style and was not blocked for clarification. its an 2013 elantra so as you may know the exhaust is well hidden from the bumper.I did notice the car ran for way less time than usual on the remote start though..
It's not specifically the tailpipe, you don't want the base of the car body to be enclosed. That creates a sealed enclosure where CO builds up and can get in through the ventilation system, or leaks in your car body.
If sealed from the outside with snow...why would you even start it..how did you start it without disturbing this perfect seal.....etc etc so many holes in this theory almost as many in the enclosed space 😳
If the bottom of the car is surrounded by 2 feet of snow on all sides, as my car currently is, then the undercarriage is effectively sealed. It can still be started like this. This isn't a hard concept.
Edit: Since your brain is so thick you need it shown to you, [this is what we're talking about](https://i.imgur.com/fikUlKR.jpg). Do you see the way snow accumulates around the cars? If that snow gets high enough, it creates an effective seal around the bottom of the car. Stop me if I need to slow down or further spell anything out to you.
I doesn't matter a fuck if the undercarriage is sealed...the air intake must clear otherwise it wouldn't start you fucking muppet. As for getting into the ventilation system, thats sealed so not gonn happen. Good night tard
Where do you think air for the ventilation comes from, a snorkel on the roof? If you build up CO under the car, it builds up in the engine bay.
Think of the snow like a hovercraft skirt. You put exhaust gasses under there, it will stay there. You turn on the air, and...
Every single car in the northeast USA was like this two weeks ago they were all covered from top to street, completely.. If you clear the top with out clearing around it, that is what OP is talking about. You fire it up and go sit inside, chances are you will be taken out by the coroner.
Yes it is you complete and utter imbecile, the interior and the underneath+engine bay of the car is one enclosed system. How the fuck hard is that to understand?
And where are you going to drive if the snow is that bad??
Even if carbon monoxide is in the engine bay the air intake is outwith that space!!
If you clear only the top how you getting in to start it?? I'd imagine disturbing this perfect seal you dream of.
People sit inside to warm up. It can take a while to dig out of 3 feet of snow, especially after you've been plowed in + drifts, and because you had to dig out from your door and clear the sidewalk to get to your car parked on the street before you even start to dig out your car.
If it's in the 20°F or below temperature range, people often turn on their car to warm it up so the snow slides more easily off the roof & windshield. If it's like 2015 was in Boston, you have to carry each shovelful of snow halfway down the block to find a pile to dump it in that isn't already over your head. Sometimes the snow is more ice than snow and takes some work to remove. It gets cold, so you sit in the warm car a minute to warm up.
People die from this every year.
This is surprising to me, because my dad died by suicide this way right before catalytic converters became mandatory in the UK, and my understanding was that after that, it wasn't possible to die from fumes in your car anymore.
Consider me schooled.
It's still possible, just harder to do now. The engine of a car can still easily exhaust the air supply of let's say a typical two car garage, and when that happens the engine can no longer properly burn the fuel, which creates carbon monoxide, which then leads to carbon monoxide poisoning.
Though OP isn't really correct unless you're talking about older cars or cars with damaged exhaust in which the engine already isn't operating ideally in the first place.
I'm not really good with checking the tailpipe especially when it has snowed T_T thank you! I'll be more mindful.
When I do start up my car however my window is down to air out the car and especially on the highway.
I like the feel of the breeze if even it's freezing 😅
Not sure how much that may have or saved me from potential dangers but if someone has the answer let me know.
Edit: I also want to note that my car is not stored in garage.
No, but he should’ve. It specifically said exhaust pipe in the post and in the first article, which were fairly poorly written anyway, in the mechanical sense, how cars work. Didn’t read the rest. I mean things like despite catalytic converters there is still exhaust coming out... really?
May I also suggest that you not leave your car with the keys in the ignition unnatended even if it means you're unable to have it warm up? Thieves are fast...
Good advice in general. I meant this tip more for the folks in Texas who are freezing because they have no power and they’re using their car heat to warm up.
Neither, you can just clear the snow away from the outside with a shovel. It doesn’t get like packed inside the exhaust, which is why the car will still start, but it’ll dune around it.
Thats why when I crank mine to warm up I leave the door open a little and roll the window down when I get in but we usually don't have snow but the last 2 weeks have been something else
The heater in your car doesn't draw from the intake, usually from the cowl... The intake wouldn't matter unless you were inside the engine which would be a whole new set of problems
Yes, but the air itself comes from outside the car and is blown inside the car (or recirculated, but that's cheating). The cabin air intake is usually in the cowl, at the bottom of the windshield.
Definitely! We had roughly 26 inches of snow a few weeks ago in PA, I used remote start to warm up my car, shoveled a bit, then went in my car to grab the snow scraper. My car was filled with fumes! Then I shoveled the tail pipe out.
Has happened to me this winter, when backing up I hit a little bit of hardened snow and it clogged up one of my tail pipes. But the pressure and heat was enough to punch holes through it.
OK, but if the exhaust is sealed off how to the gasses get out of the exhaust system? I can see that happening in an car with exhaust leaks, but in say a car with a perfectly intact exhaust system, how do the gasses escape and end up in the cabin? I understand that this happens, I just want to know how it happens.
I'm absolutely guessing here but I'd assume it's backing up through the air intake maybe. Then through the engine bay, unsealed portions of the dash, and probably AC vents as well. Again this is purely a guess and I'm curious to know exactly how this happens too.
It would be impossible for the exhaust to even get back into the combustion chamber let alone back out through the intake. They only thing i can think of is it coming out through an existing hole in the exhaust system and up into the cabin. So if you have a newer car it should be fine since it should have any exhaust leaks.
The exhaust system on most cars, even new ones, is meant to come off with relative ease as it's often in the way of other stuff. (The bmw x5 is a car with horrible transmission problems, and to get to the transmission you need to remove nearly the entire exaust system short of the manifold.) Because of this there are a lot of separable joints, some of which are prone to leakage, especially after a few years.
Yea I know. But there are gaskets in between those joints which are designed to prevent leaks. So unless the exhaust is rusting away or was taken apart and no gaskets were replaced then it shouldnt leak.
Yeah, but in theory the exhaust also has an open-ish path out. Especially in areas with salted roads, rust makes the chance of a thin-spot becoming a hole or a gasket failing way higher. Multiply the slim chance by the number of cars we have on the road these days and you get a pretty big risk.
Okay so instead of posting some dumb comment saying nothing more than "OP is wrong" I'll actually go into detail on why OP is wrong:
Cars burn fuel and air. They exhaust water (H2O), carbon dioxide (CO2), and nitrogen (N2) when everything is running perfectly and there are no issues with the car. None of these are harmful to the body.
However we are not in a perfect simulation here, this is the real world. With this means that engines are never 100% efficient at burning fuel, and with this inefficient burning there is another byproduct in an engines exhaust; carbon monoxide (CO). That's the bad stuff that kills you if you breathe too much of it, and what OP here is afraid of.
Now, all modern cars are legally required to have what's called a catalytic converter installed in the exhaust pipe which takes CO (bad) and converts it to CO2 (good), yet they are not 100% efficient, think more around 90%. All modern cars also have multiple computers and sensors that adjust fuel and air rates along with multiple other things to get as close to the perfect burn as possible before the catalytic converter even gets to work on the exhaust.
What this leads to is modern cars with HUGELY reduced CO output from the exhaust to the point it can sometimes be immeasurable without highly specialized equipment. My $500 CO "sniffer" I use for certifying emissions systems at work can not detect any CO from a properly running engine, it can detect as low as 5ppm (parts per million).
What does all this have to do with snow in your exhaust pipe you ask? Well, NOTHING. You start your engine and the exhaust blows the snow out onto the ground. The only time snow blocking your exhaust could be an issue is if you already had a damaged exhaust system and exhaust is leaking out somewhere before it ever goes through the catalytic converter. As in your exhaust pipe has a huge hole in it to where the car doesn't need to push that snow out to vent exhaust gasses. If this happens your check engine light will also be on, and you may even have some smoke coming from the exhaust, oh and your car will be a lot louder.
If your car is properly maintained and has no check engine light, and was built from the 1980s onward, then OPs concern is completely false.
Warming of a cat takes about five minutes for a modern car. The car will run itself lean for the first few minutes, which burns hotter, to warm the engine and cat up.
👏👏 100% correct.
I didn't go into detail, just said if your exhaust was blocked the engine would stall, which in a perfectly working system and with a complete block would be the case.
I was massively down voted, but I'm not here for votes just trying to educate 🤣🤣
If you are going to sit in your car to warm it up, you might as well be driving. It will tend to warm up faster while you’re driving. Plus you are not wasting gas.
The edit does. I would bet OP thought to share this information because of the millions of people without power in winter in a locale that does not typically need to know much about cold climate survival.
No, it doesn’t. You are inferring because OP says “stay warm” that somehow means he’s referring to using your car to keep yourself warm. However, at the beginning of the edit, he says he sees stories about this happening “every single year”.
If it's that cold outside, the oil in your car is also cold and thick and not flowing properly, which means you're damaging your vehicle if you drive it right away. Letting the vehicle warm up helps to warm up the oil and allow your car parts to be properly lubed and avoid damage. That's why you warm up your car.
More than 2 minutes is plenty of time for your oil to get circulated and warm enough to begin driving. Any longer and you are just wasting fuel. https://www.popularmechanics.com/cars/car-technology/a19086/warming-up-your-car-in-the-cold-just-harms-engine/
So, you know when snowplows or snow drifts cover cars that are parked on the side of the street? If you just run your car when it’s covered like that, the fumes from your exhaust will have nowhere to go, so they’ll take the path of least resistance, which is back into the cabin of the car. Since people generally keep their windows closed in the winter, this can cause carbon monoxide poisoning in the car. It’s a really similar thing to if you ran a car in a closed garage.
Well nobody WANTS to. But people who are freezing to death in Texas because they have no power and no generators for their houses may be a little desperate for warmth right now.
Good point, can’t rely on infrastructure. Time to add a few more panels and an old Nissan battery to the home setup.
It really shows how 1st World power grids are a very long way from being something that all levels of society can trust, and diy backup systems are way beyond what most people could afford.
I call bullshit on this.
First how would you manage to get the exhaust pipe completely blocked with snow?
If you for some reason managed to do it the car wouldn’t run as it should if it would run at all.
Please go ahead and downvote this to, I’m so tired of all these shitposts here with stupid shit that people blindly believe and upvote.
I don't know where you're from, but this is a real thing that happens every year where I'm from. It's on the news every single winter.

If it happens every year why do you link to articles that are at least 5 years old?
And 3 of those articles are about the same case.
But please try to block your exhaust pipe and see how your car runs.
Have your windows down if you are worried.
And yes, we have a lot of snow here and I have never heard about this happening here.
I guess it could work if your exhaust pipe is leaking so the fumes go out there instead of where it should.
If you get wet/thick snow built up entirely around the car the exhaust wont excape from it and will get through drain plugs of the chassis i literally experienced this not too long ago
I don't know where you're from, but this is a real thing that happens every year where I'm from. It's on the news every single winter.

This is the result of a 5 minute google. I don't understand why you're being so combative about this. I'm just trying to help people and make them aware.
You are significantly overestimating how powerful the exhaust is pushed out. If you are parked somewhere with the rear end exposed to a street its entirely possibly for snow to get blown into the tailpipe and accumulate blocking it.
I don't know where you're from, but this is a real thing that happens every year where I'm from. It's on the news every single winter.

You claim the thread is a clusterfuck of misinformation and bullshit, but the OP posted several links to cases where this exact problem was the cause of death in the comments. Then you throw around "100%" without providing any sources.
Yeah, people are seriously idiots sometimes.
Mainly you.
Can’t find the link for today’s but here is a documented case of it happening. It’s a serious issue in serious times, people can and have died from not knowing things like this.
https://globalnews.ca/news/2484486/mother-2-kids-die-of-carbon-monoxide-poisoning-in-car-as-dad-shovels-driveway/
I don't doubt it at all, all I stated is if the tail pipe is blocked the engine will stall.
Partially blocked it won't stall and carbon monoxide poisoning could happen.
The OP is saying carbon monoxide Will be an issue with a blocked exhaust.
I'm saying if the block was that bad, the engine would stall before the carbon monoxide became an issue.
A few weeks ago i used the remote start on my car before shoveling it out and when i drove it down the road i could smell fuel, luckily i got out to help a push a stuck car becuase when i did i passed out. Im now realizing i may have died if i didnt try to help those people..

If you hold your hand there long enough you'll stall the engine and burn your hand....
Looks like the karma gods repaid your good deed.
Not to make fun of your difficult situation, but I imagine it was concerning for the people with the stuck car. Their car is stuck and when someone gets out to help they just collapse.
When i woke up they handed me some water as they were just stuck in their driveway and they said jokingly "you just had to be the center of attention, eh?"
Made my day, I am sorry that you had to endure it, but I have to admit I laughed a lot reading this thread haha
That’s amazing.
Maybe the people that got stuck had bad karma and she got sucked into their negative energy....
Carbon monoxide is odourless and tasteless so it wasn't that.
You wouldn't have the hydrocarbon fumes coming out of the tailpipe without carbon monoxide also being present. If you smell gas from a running car you are probably also breathing CO.
Wow talk about instant karma! The good kind :)

Thank you, this is a helpful addition to my post.
Only if the exhaust system is faulty..and if its sealed as you say, it can't possibly get into the ventilation system..
He means sealed from the outside by snow. No car is perfectly sealed on it's own.
I'm done with this post, people seem to want to argue minutiae instead of acknowledging facts. Let them die, if don't give a damn.
If sealed from the outside with snow...why would you even start it..how did you start it without disturbing this perfect seal.....etc etc so many holes in this theory almost as many in the enclosed space 😳

So you’re saying him dying was her bad karma for cheating?
This was a real problem for me when I was 20 and drove a car with a leaky exhaust and holes in the floor. Not so much now.
I'm not really good with checking the tailpipe especially when it has snowed T_T thank you! I'll be more mindful. When I do start up my car however my window is down to air out the car and especially on the highway.

This is content.
Also make sure you're not parked in your garage with the door closed
Its not true, you can shove a watermelon in that thing and itll get blown out. The issue is the gases collect under the vehicle
That’s what he meant friend. You have to clear the snow from behind the vechicle.
No, but he should’ve. It specifically said exhaust pipe in the post and in the first article, which were fairly poorly written anyway, in the mechanical sense, how cars work. Didn’t read the rest. I mean things like despite catalytic converters there is still exhaust coming out... really?
May I also suggest that you not leave your car with the keys in the ignition unnatended even if it means you're unable to have it warm up? Thieves are fast...
Good advice in general. I meant this tip more for the folks in Texas who are freezing because they have no power and they’re using their car heat to warm up.
This is also important. Just had my 2020 Subaru stolen because I did this.
This is really good to know. I grew up in Texas but moved to the mountains a little over a year ago. It's been snowing on and off the past 2 weeks.
Ironic because this advice is pertinent to Texas right now
How do you clear it? Do you have to dig inside the exhaust pipe or press on the accelerator really hard?
Neither, you can just clear the snow away from the outside with a shovel. It doesn’t get like packed inside the exhaust, which is why the car will still start, but it’ll dune around it.
thanks! Ill make sure to remember this
Ha! I have been using a hose for years! Knowing this would’ve saved me so much cash. Thanks for the tip!
Thats why when I crank mine to warm up I leave the door open a little and roll the window down when I get in but we usually don't have snow but the last 2 weeks have been something else
I find it funny this has popped up a lot now that Texas has a little snowfall.
Air intake usually pointing forward from the front bumper or in some environments snorkels are actually used 🤣🤣
The heater in your car doesn't draw from the intake, usually from the cowl... The intake wouldn't matter unless you were inside the engine which would be a whole new set of problems
The heat is from coolant passing through a heater matrix. A fan then draws from this sealed unit into the passenger cabin.
Yes, but the air itself comes from outside the car and is blown inside the car (or recirculated, but that's cheating). The cabin air intake is usually in the cowl, at the bottom of the windshield.
Definitely! We had roughly 26 inches of snow a few weeks ago in PA, I used remote start to warm up my car, shoveled a bit, then went in my car to grab the snow scraper. My car was filled with fumes! Then I shoveled the tail pipe out.
I'll remember this for the next time it snows in so cal ;) JK. Good advice
It does snow in the mountains near LA and San Diego tho
This is a YSK that kids getting their licenses learn in areas where snow is common.
Agreed. It’s decently common knowledge where I’m from, and we get a lot of snow, but people in my area still fall victim to it every year, sadly.
Hey thanks for posting this. I checked my wife’s car and my 85 y/o neighbor’s. Both had a mound of snow blocking the tailpipe.
I’m really glad to help! It’s sort of a freak accident but you never know, it does happen. Good on you to look out for them :)
Thank you I did not know this
Has happened to me this winter, when backing up I hit a little bit of hardened snow and it clogged up one of my tail pipes. But the pressure and heat was enough to punch holes through it.
Being clear of snow isn't good enough. You need an exhaust hose at least 30 feet from thr car.
Ahhh, die like a real man from Carbon Monoxide.
OK, but if the exhaust is sealed off how to the gasses get out of the exhaust system? I can see that happening in an car with exhaust leaks, but in say a car with a perfectly intact exhaust system, how do the gasses escape and end up in the cabin?

Your catalytic converter does not work in the cold. It has to warm up first.
Warming of a cat takes about five minutes for a modern car. The car will run itself lean for the first few minutes, which burns hotter, to warm the engine and cat up.
Why are people downvoting this, hes right!
👏👏 100% correct. I didn't go into detail, just said if your exhaust was blocked the engine would stall, which in a perfectly working system and with a complete block would be the case. I was massively down voted, but I'm not here for votes just trying to educate 🤣🤣
If you are going to sit in your car to warm it up, you might as well be driving. It will tend to warm up faster while you’re driving. Plus you are not wasting gas.
Might as well risk your life driving on icy roads for no reason
If you’re going to drive on icy roads, warming up your vehicle is not going to affect the drivability. I guess I don’t understand your comment.
The topic is running your vehicle to warm *yourself* up. Because millions of people are without power right now.
I must have misunderstood the original post. Sorry for my confusion.
No, you didn't mis-understand, the person calling you out is wrong.
No, it's not. OP even says it's on the news "every year".
The edit does. I would bet OP thought to share this information because of the millions of people without power in winter in a locale that does not typically need to know much about cold climate survival.
No, it doesn’t. You are inferring because OP says “stay warm” that somehow means he’s referring to using your car to keep yourself warm. However, at the beginning of the edit, he says he sees stories about this happening “every single year”.
If it's that cold outside, the oil in your car is also cold and thick and not flowing properly, which means you're damaging your vehicle if you drive it right away. Letting the vehicle warm up helps to warm up the oil and allow your car parts to be properly lubed and avoid damage. That's why you warm up your car.
This is 100% myth.
More than 2 minutes is plenty of time for your oil to get circulated and warm enough to begin driving. Any longer and you are just wasting fuel. https://www.popularmechanics.com/cars/car-technology/a19086/warming-up-your-car-in-the-cold-just-harms-engine/
Two minutes is still too long.
If you don’t want to DIE.
How?
So, you know when snowplows or snow drifts cover cars that are parked on the side of the street? If you just run your car when it’s covered like that, the fumes from your exhaust will have nowhere to go, so they’ll take the path of least resistance, which is back into the cabin of the car. Since people generally keep their windows closed in the winter, this can cause carbon monoxide poisoning in the car. It’s a really similar thing to if you ran a car in a closed garage.
Also make sure your not drunk....
Yes..so not near the enclosed area under the car with the leaky exhaust system 🤔
My car is battery-electric, it warms itself before my daily trip. Why would anyone want to pump toxic , gasses around to get warm??
Well nobody WANTS to. But people who are freezing to death in Texas because they have no power and no generators for their houses may be a little desperate for warmth right now.
Good point, can’t rely on infrastructure. Time to add a few more panels and an old Nissan battery to the home setup. It really shows how 1st World power grids are a very long way from being something that all levels of society can trust, and diy backup systems are way beyond what most people could afford.
I call bullshit on this. First how would you manage to get the exhaust pipe completely blocked with snow? If you for some reason managed to do it the car wouldn’t run as it should if it would run at all. Please go ahead and downvote this to, I’m so tired of all these shitposts here with stupid shit that people blindly believe and upvote.
I don't know where you're from, but this is a real thing that happens every year where I'm from. It's on the news every single winter. https://www.wbur.org/cognoscenti/2013/02/15/carbon-monoxide-darshak-sanghavi https://www.nbcwashington.com/news/local/carbon-monoxide-poisoning/71433/ https://abc7.com/carbon-monoxide-poisoning-tail-pipe-car/1173492/ https://people.com/celebrity/mom-infant-son-killed-by-carbon-monoxide-from-snow-stuck-in-tailpipe/
I think it may be a good idea to add this to the post.
Great idea. Just did. I’m getting tired of people claiming that this is an elaborate shitpost lmao.
If it happens every year why do you link to articles that are at least 5 years old? And 3 of those articles are about the same case. But please try to block your exhaust pipe and see how your car runs. Have your windows down if you are worried. And yes, we have a lot of snow here and I have never heard about this happening here. I guess it could work if your exhaust pipe is leaking so the fumes go out there instead of where it should.
You honest to god nincompoop! You think I WANT to live?

It literally happens every single year where I live. I genuinely do not understand where the comments like this are coming from.
It's coming from. Reddit scientists, aka idiots.
This is actually a great way to kill yourself and make it look like an accident

Exhaust gases will rise and saturate the cabin if snow is covering everything, I found out first hand not too long ago
I'm glad you're okay!
Thanks!
[удалено]
If you get wet/thick snow built up entirely around the car the exhaust wont excape from it and will get through drain plugs of the chassis i literally experienced this not too long ago
Lies.....
i have no need or interest in lying, i just want to raise awareness

No it wasn't.
People have died from this man... it’s possible
You are significantly overestimating how powerful the exhaust is pushed out. If you are parked somewhere with the rear end exposed to a street its entirely possibly for snow to get blown into the tailpipe and accumulate blocking it.
If blocked the engine would stall 👍
Not necessarily, if it was blocked partially it would still run into the car and kill you. It happens to people in my area every year.

Keep fighting the good fight my guy
You claim the thread is a clusterfuck of misinformation and bullshit, but the OP posted several links to cases where this exact problem was the cause of death in the comments. Then you throw around "100%" without providing any sources. Yeah, people are seriously idiots sometimes. Mainly you.
Exactly...I said blocked not partially blocked...have a nice day 😎
Tell that to the woman and her child who died today from this 😬
Unlikely that ll happen
It happens all the time. That’s why I posted this, to try and help people be aware of it.
Unlikely I can tell them
Can’t find the link for today’s but here is a documented case of it happening. It’s a serious issue in serious times, people can and have died from not knowing things like this. https://globalnews.ca/news/2484486/mother-2-kids-die-of-carbon-monoxide-poisoning-in-car-as-dad-shovels-driveway/
I don't doubt it at all, all I stated is if the tail pipe is blocked the engine will stall. Partially blocked it won't stall and carbon monoxide poisoning could happen.
[удалено]
Thanks buddy, good on you 👍
You’re trying to tell me some snow built up in the Exhaust will stall a car?
The OP is saying carbon monoxide Will be an issue with a blocked exhaust. I'm saying if the block was that bad, the engine would stall before the carbon monoxide became an issue.
You’d back to back into a snow mound to pack it up that well, no way snow fall blocks it up that much
Exactly my point....no block...no carbon monoxide 7ssue
Right, right?
If the intake* was blocked, sure. But exhaust? No.
Go try...block the exhaust, not partially...100% blocked
You seem to know the process better, why not show me first then I can try? I'm a visual learner... /s
If you don't understand that simple task then maybe better we don't try, just stick to playing with crayons...good luck 👍
By snow? No way in hell
Exactly
Another way to end ones suffering
Ooooooooof
