rev up your engines, if your car has water leaking inside it, then today's
your lucky day cuz I'm gonna show you how to find where the leak is coming
from and how to fix it, now water leaks come from about four main places in
cars, the first one is if it only happens when you turn the AC on, that means your
AC evaporator is clogged up, the water's building up and spilling inside the car
so, jack your car up in the air and stick a jack stand under there so you don't
get crushed, then crawl under the car and look for the drain hose now it's a black
rubber hose that in many cases you can see from the bottom but in this case
this power steering is in a way so we'll get to it from the top and we'll go
inside the hood here's the firewall when we go down here, here's the AC drain hose
there's the end of it here, something inside gets clogged up all you
have to do is put a garden hose over this little hole and in this case the
garden hose is a little bit too big, so I get another hose that I can stick the
garden hose in and then stick the other end of this hose I'm the drain hose to
clean it out, the other end of this hose just slips right over the drain hose and
if you want a tight fit, you can put a little duct tape on it so that it's
really tight and it doesn't leak, then you just give the hose a bunch of
quick bursts and that can clean out the debris, it can be that easy just do it
every once in a while and pray that you don't have a Jeep or other chrysler
products cuz many of them, the drain hose is inside the frame of the car and you
can't get to it they were evil, you gotta take the whole dash apart to clean that and
it cost a fortune, another reason not to buy them and don't put your hose away yet
cuz here's the second place that they often leak from, your intake vents
suck in air but they also suck in dirt and leaves and there is an actual
little drain dam that runs under them and the water is supposed to drain down to
the fender and come out right down here, as you can see here there's some of the
dirty little needles from the trees that fall out they're trying to make their
way through, you got to make sure that this drain is clean and not clogged up
with stuff, mine is getting clogged up with stuff, so you get your hose again
and squirt it off, clean all the crud out and if it's
really bad like this, you might have to get an ice pick or get an old coat
hanger take it apart and poke it up there to get all the crud out, because if
these drains get clogged up, then the little drain areas that they go
through the little gutters will back up and water will come dripping inside the
car and the same thing holds true for the inside of your doors, look at this, the
inside of the doors they have a little drain holes in it too, here's the drain
hole, you need to clean these out every once in a while because none of these
seals on the windows are perfect their not made to be, water always gets in gets in
the door and then it drains out the bottom, those drains are clogged the door
will fill up with water and water I'll get in the car and you'll hear it sloshing when
you take corners and speaking of water leaks, check the trim inside the seals
make sure it's not cracked, look at that my own car tried to bite me, now being a
professional mechanic I actually have ultrasonic machines that can find these
leaks where there's holes faster than you can, I use this ultrasonic bomb you
turn it on, you're not gonna hear anything, but it makes an ultrasonic
sound and you throw it in the car, then you put on these headphones plug them
into the ultrasonic listening device and check for where there's an air gap
you'll hear the noise coming out louder, when the noise gets loudest that's where
the break in the material is and then you'll be able to find the rip even
faster, well I doubt most do it yourself guys are gonna go buy this but the
advantage of this is, let's say that the trim isn't cracked but the door or the
window is askew and it's not gripping right in one part, this will pick it up
really fast, but if you want the cheap man's way to find air leaks where water
can come in, just get a bucket fill it with water and a little vegetable dye
like red that really stands out then when you pour it all over on the inside
where you see red dye coming in, you know that's where the leaks coming from, now
the fourth and last one I'm talking about today where leaks commonly come
from, are sun roofs leaking, now it might sound a little crazy but all Sun roofs
leak to some extent, the seals out here aren't perfect seals there's little
drains inside to sunroof that take the little bit of excess water that get in
and drain them out on the bottom of the car, when you look inside the sunroof
look right here, there's a drain hole that big circle, now some cars have as
many as four drain holes in their sunroof, find out how many yours has and clean them
every once in a while, you can squirt a little
hose in there to clean them, sometimes I used a little compressed air, you just
want to make sure it's clean because you're always getting water inside that
drain pan inside it, that top seal isn't perfect and if those little holes clog
up, then it'll start dripping it on the top and get all over the place, now I
have to clean my wife's all the time because I park it under this beautiful
Chinese Arbor Vita tree, which puts a lot of stuff out, so I'm always cleaning it
out so she doesn't get wet, it's a little more labor-intensive yes but being on
hot humid Texas that shade keeps this car looking good and keeps the leather
from cracking, so I don't mind cleaning it every once in a while to save all
that other stuff by putting it in the shade, so now you know how to find and
fix water leaks in your car, so if you never want to miss another one of my new
