Rev up your engines!
It's time for the Scotty Kilmer Channel
if your worried about your car passing the yearly emissions inspection, then stay tuned
because today I'm going to show you how to prepare your car to pass the
emissions inspection, now many places require that every year you have your
car inspected, to get this inspection sticker, now part of the test is a safety
test, checking things like tires, to make sure
they're not bald and brakes work okay, and to make sure that your headlights
work, now that stuff's pretty cut-and-dry anybody can check it, but when it comes
to emissions inspection, since your nose can't really tell what's coming out of
the tailpipe, there's a few preventative measures you can do to make sure it
passes the emissions testing, now in an older car like this 93 Celica, they
actually measure the gas that comes out of the tailpipe with a dynamometer test,
so you want to make sure everything is working fine, so the gases that come out
of the pipe, are very low and aren't polluting much, so first make sure that
the oil is clean, change the oil and filter before your inspection, because if
the oil gets dirty, the PCV system can suck a lot of those dirty vapors in
burn them, and pollute more, of course you want to have clean oil anyway, but right
before the inspection is the best time to have the cleanest oil, and the next
thing to do is, to make sure the air filter is clean, because if you have a
dirty air filter it'll block the air, the car will run lean, and it'll pollute too much
a lean running car makes the engine run hotter, the exhaust gases get hotter, puts
out more NOx, which is a pollutant they measure, and you can fail the test
and of course, check your spark plugs to make sure they're in good shape, spark
plugs have a gap where the electricity fires, and when it's old and worn out, when the
gap is too big and they don't work right, and even if a car is running okay if the
gap is too big, it'll pollute more and you'll fail the test,
and of course check the cooling system, because if the coolant is low the top of
the engine will get air in it, make it run hotter and it'll pollute more, and
here again realize that the engine doesn't have to be overheating on the
gauge to make part of the engine still running too hot, so make sure it's full
of coolant and that it's clean, and of course make sure that the cooling fans are
working correctly, turn on the AC, at the fan and make sure that it's spinning
like this fan is spinning, because the test takes place on a dynamometer, the
car isn't moving, if those cooling fans aren't sucking air,
the engine will run hotter and it can fail the test, now if you have a more
modern car, like this three-year-old mini, they don't test them on a dyno they just
plug into the computer to see if there's a problem, all cars from 1996 on are
tested this way, so if you have a 1996 or newer car and a check engine light is on,
you need to fix it before you go to get inspected, because that means there's a
trouble code stored in the computer and when they inspect it, their computer will
fail it for the test, and there's over 2,000 separate trouble codes that can
exist in a car, so can get really complicated when a light comes on, but
let's say you're unluckly and you've already done everything I've shown in this video,
and your car still fails the emissions test, well you can try fuel injection
cleaner poured into the gas tank, and drive the car really hard on the highway
about 70 or 100 miles, personally I've had very good luck using the shop line
solvent, I just pour a gallon of the solvent to about half a tank of gasoline,
then I go on a highway and drive the car at the maximum speed limit, for about
half an hour or 45 minutes, I've done this on hundreds of cars and got them to
pass the emissions test after doing this, of course this is not a magic fix if the
car doesn't run good, it's got a serious problem that needs to be fixed, but if
the car runs okay this can often let it pass the test, because the solvent burns
really clean, so the gas coming out of the exhaust can get cleaner and cleaner
as it cleans all the systems out, and if you have a late model code with a check
engine light, and it says inefficient catalytic converter try this first because
it will often clean them up, so they'll pass the test, so now you can stop
worrying about your car passing the emissions test, and do something about it
and remember if your car has any problems just visit the Scotty Kilmer

before it's too late!
