one, two, three, four!
Rev up your engines!
It's time for the Scotty Kilmer Channel
today I'm going to show you how to keep your car's air conditioning blowing ice cold,
now car air-conditioning systems are sealed systems, so there isn't that much
maintenance, but what little there is, you can easily do to keep your air
conditioning cold for years, and the first thing you can do is go to your air
conditioning Inlet under the hood, and take all the leaves and debris that are
under there, so they don't get sucked up into the vent system, because if they do
and get inside the evaporator, where the cold air blows through, it'll clog it up
and water will build up and leak all over the car, and when that happens, it'll
also work inefficiently because the evaporator will have a lot of water in
it, and it'll keep it from dissipating the heat and you won't get as cold air
blowing in your face, and speaking about dashes, perhaps the most forgotten thing
is a cabin air filter, many modern cars have a cabin air filter, to filter the air
going to the air conditioning, in this case, you have to take out the glovebox,
and in the case of this Toyota, you can just squeeze the side, and the whole thing
comes out, it's easy in this Toyota, because the nubs on the side, you
squeeze them in, and then they come off of this piece on the inside and the
whole thing just pops right out, then the cabin air filters just hiding in here,
you squeeze these two tangs, out it comes, now I recently change this one about a
month ago, but as you can see, it's already getting a bunch of dirt in it,
so every once in a while, you can just take it out, hit most of the crud out, and then
put it back in, and if you're really sensitive, you can buy more expensive ones
that have carbon activated filters, and they'll get rid of a lot of the stench
outside, by filtering through the carbon, just, so since these filters are
relatively new inventions, a lot of people don't think about it, so they clog
up, when it clogged up, your air conditioner will really work poorly, so you
want to check them at least every 2 or 3 months in the summer, when you using the
a/c a lot, then when you're done, you just snap the
glove box back in, and screw this little dampener back in place, so it goes in and
out easy and doesn't snap, now the last thing you want to check are the cooling fans
in your radiator, to make sure they're working, so the a/c gets cold, with the
car running, turn the a/c on full blast, then go under the hood and check the fan, put your
hand, make sure it's blowing plenty of air like this one, and that's important,
because even though the fan is on the radiator, when you go in front of the
radiator, you see the condenser, this is the air-conditioning condenser, it has to
have air blown through it, to make your air get cool when you turn your air
conditioning on, and if you have a system like in this Toyota that has two cooling
fans, let it run for five or ten minutes with the a/c on full blast, and both fans
should be blowing hard, if they aren't, and only one works, you're going to have a
problem in the long run, and in the short run, it's still not going to blow as cold,
because you don't have enough of your circulating, and realize that all these
fans may cost over 300 bucks new at the dealer, you can often get an entire
chinese-made assemblies, and both fan units might only cost you about a
hundred bucks, for the pair, while I'm talking about air flows through the
condenser, you notice mine here is all clean, and that's because I just
cleaned it off from a trip to Austin where a lot of bugs got stuck in it,
anything that restricts airflow is going to make the air-conditioning work poor, so
if you have a lot of bugs, just do this, get a garden hose, hydrate the bugs so
they get wet, wait about 20 minutes, make sure you get everything nice and wet on
the condenser, then after they're all hydrated, they'll start to come off
easier, you just hose them off again and if any of them stick, you can just get
any kind of sponge, and you could just wipe the pieces off, while you're
at it, you want to check your fan belt to see how the fan belt that drives the air
conditioner looks, you don't want to see a bunch of little cracks, then you don't
want to see that it's slipping, and making squealing noises, when you have a
fan belt like this, that has lots of little cracks in it, you need to change
it, before it starts to slip and it can make the compressor burn out if it's
always slipping and turning on and off, fan belts don't cost much, compressors
cost a lot, so change out the belt when it starts to wear,
and the last simple thing for your air-conditioning to do, is to check your
radiator fluid, because as crazy as it sounds, if your radiator coolant is low,
and your cars running hotter, modern cars have sensors and they'll actually turn
the air-conditioning compressor off in order to keep the car from overeating,
that's why the systems and cars are called HVAC, for heating ventilation air
conditioning and cooling, because they all work in conjunction with each other
and a problem one, can affect a problem on the other, so if you want to stay a
cool cat in your car, now you know how to maintain your car's air conditioner,
if you've got any car questions just visit the scotty kilmer channel and I'll
answer them as soon as I'm done redecorating my garag, well you all
complained that it was too messy, so hey, I cleaned it out entirely including the
roof
