Never Do This to Your Car (Learn From My Mistake)

today i'm going to show you why you should not drive your car through water using this 2014 dodge challenger with a v6 engine as a prime example now we recently had a tropical storm come in through a bunch of water in houston unfortunately this woman drove through the water she said it didn't look that deep but the car started acting up you should have watched my video beforehand one don't go through the water and two if you do shut the car off immediately do not try running because the air we breathe compresses quite a bit inside an engine compresses fuel sprayed in it ignites if water gets sucked into that mix the water compresses a very tiny amount but not much so if you suck a bunch of water when the piston goes up instead of squishing air it can't squish the water much so what happens is it bends the connecting rod on the piston that goes to the crank once it's bent the engine starts running funky so the first thing you do check this open the hood check the air filter in this case the air filter is sopping wet this baby sucked water into the engine you don't want to run an engine that way you want to take this plastic cramp off and check the spark plugs because if you're lucky the water is in the engine and it hasn't compressed yet get this out of the way you can see water's coming out not a good thing we're gonna pull the spark plugs out three on each side first we take off the coil take the coil off unbolt it pull it out remove a spark plug take all the spark plugs out because you're making them long out it comes and it smells plus it's wet remove all six spark plugs that one's wet too and before we crank it over we're gonna check the engine oil we'll stick it in see if water's intruded inside the engine and it has because it's over filled and i do have to say in this case i don't have much hope because unfortunately she drove through the water and kept driving until it died generally then the rods are going to be bent from water getting inside and collapsing it got deep enough that not only did it suck water into the pistons but it sucked water into the engine oil too so this thing just went too deep in water that's a disadvantage of a load of the ground car they go faster less drag they look cool but if you take out the air filter and see the air is being sucked from it's being stuck from way down low way in here weight on low it's a racing thing for speed race cars do that too this one went through flood waters and sad but true it's probably a losing effort but after changing the oil let's crank the engine over see what it does if it hadn't been run at all we could push the water out of the holes by cranking it let's see what happens now unfortunately the only thing we really see coming out is air and a little bit of fuel that's being sprayed into the cylinders it hadn't been run after it went through the water the water could have gotten into the air filter and on the intake but not sucked into the engine and then tons of water would shoot out while we're cranking it didn't really come out so odds are this thing has been damaged let's put it back together and see what happens you can see there's still water in here so we're not going to put that back on we're going to leave that off spark plugs back in get it nice and snug now we'll put the ignition coils back on you want to get them on tight so they're grounded now we're going to crank it up and see what happens the horrible knocking horse here is rod knocked the engines have been destroyed by water now in this case there's no sense in going further who knows the computers might be ruined from getting wet and stuff but she said the water wasn't that deep it doesn't need to be that deep to suck water in the engine and ruin it and that's because as i said previously air compresses quite a bit but water only a tiny amount so when you get a bunch of water in the cylinder when it fills up and then it goes up for the firing event the piston has to compress it it's got to go a certain distance if that's full of water it can't go the whole distance so instead of going the whole distance what it does is it bends the piston rod now if it's really bad sometimes it'll actually crack the block and do even more damage but in this case the engine's toast and would need a complete rebuild at least it's a three liter vvt the v6 engine the hemi engines are very popular all the kids won and the racers want them these v6 is not so popular so if she can find a used one in a junkyard from a wreck she could have that installed now i had a customer do that a couple years ago they spent about 1400 bucks for the engine and labor at a junkyard most mechanics are gonna charge a lot more than that but if you can find a junkyard that'll sell and install an engine that's what they're going to advise her to do she owes so much money on now if she would have full coverage hey that water came up the insurance company would pay for the damage she did not have the coverage it's coming out of her pocket so she's either going to lose a ton in what she owes for this or put a used engine in it and so what's the moral of this story you might think the water is not that deep because your air filter's up here but in this case the intake is way down there as you can see it doesn't take that much water to suck in then it's good by engine and it's all because air compresses a lot engines are actually giant air pumps they suck air in they pump it out as fast as they can but unfortunately they are not water pumps you do not want water sucked into the engine and blown out because that will bend the piston rods at a minimum destroy an engine that was otherwise running perfectly fine hope that a junkyard's got a decent engine sell it at a decent price prey it doesn't go through any water that's just even that deep anymore when it really starts raining you got a low racing car like this sucking air from the bottom you don't want to drive through it that's why you see guys with those jeeps they put big snorkels that go up to the top and that's where the air sucked in and of course even they're gambling it doesn't get too deep to suck water into the engine and into the transmission a lot of those are diesels and they work differently since they don't have an ignition source they can run in water quite well a lot of tanks can go underwater with a snorkel but cars not so much especially if you got a gasoline engine with an intake duct low see these fake air intakes you open the hood they don't go anywhere it just for show and as i've already shown this baby's sucking the air from way down here low not a good thing when you're driving in the rain so the next time it starts raining cats and dogs head for the high ground like scotty does do not try to drive your way through it in a modern car and here's some bonus questions and answers caveman luke says hey scotty i got a 2016 dodge journey carvana's offering me 10 and a half grand and i owe 11. now unfortunately i can afford a highlander or a pilot my wife doesn't like the rav4 it leaves me with a sorrento santa fe or ford edge they're all 20 16 18 with v6 engine which would be better i would say just get an older toyota or an older honda myself but you're trying to upgrade from a journey just about anything is an upgrade from a journey i'm amazed that they're even offering you ten and a half grand for that thing out of those two i'd buy the sorrento santa fe the ford edge does v6 engines they're going to be ecoboost engines they don't hold up they got those stupid water pumps that are chain driven that when they break they can destroy the engine realize they'll last forever but generally the last at least a hundred thousand miles relatively trouble free with the sorrento santa fe so what the heck i mean you might go that way i would just buy an older toyota honda myself because they're much better mate but if push comes to shove and you got to get one of those don't get the ford not with that engine james 73 says i got an o2 toyota camry it stalls every once in a while and it has the trouble code p101 i replaced the mass air sensor that made no difference help make your car run better with a little spray cleaner i fixed one six months ago with the same exact problem turns out your throttle the throttle plate opens and closes well like when it closes there's only a little gap i need a little gap carbon will build up over time then it'll give the wrong data it'll always trip that po 101 code so if you do my video and spend a lot of time cleaning the throttle you'll know when you take off the big air ducts there's the air filter take that off and the duct going to the engine where the duct goes onto the engine that's where the throttle is you'll see the big throttle plate inside the video explains it all it's really easy to do but you'll probably see if you get a flashlight look in there it's probably all black with built up carbon and then it'll stick and when you use the throttle spray cleaner to clean it that'll fix your whole problem now when you're done it'll idle weird for a day or two as it sets itself back up but you probably find that'll fix the whole thing because i have fixed literally hundreds of toyotas that way over the years just by cleaning the carbon off of the throttle plate i mean geez the thing's 19 years old and it gets dirty and maybe it's never been cleaned you only need to clean it once every couple of years maybe but it's been 19 years it's probably never been touched so if you never want to miss another one of my new car repair videos remember to ring that bell [Music] you
