rev up your engines, robbed Lopez hey Scotty can I do
mechanical damage my car if I turn it off with the shifter still in Drive, well not
really as long as you have your foot on the brake and the car's not moving
anymore, I know a lot of people that do that, they come to a stop they
leave it and drive then they put the emergency brake on then they shut the
car off, so then the weight of the vehicle is on the locked emergency
brakes and not on the transmission, let's say live in San Francisco you got an
automatic transmission, if you park on a hill put that thing in park and then
shut it off and then put on the emergency brake you put a lot of strain
on their transmission prog gear, that holds it in place it's better to use the
brakes first than later, put it in park if you live in really hilly environments
now you feel live in a flat place it really doesn't matter what the heck you
do, there's no strain on it at all Josh Newbie hi everybody, for oil changes
what matters most time or mileage, well it's a combination, if you use normal oil
you can change it every three to five thousand miles non-synthetic normal
oil, if you synthetic oil you can change it like every seven
thousand miles, I like being conserved regardless of the type of oil you use,
you need to change it at least once a year I don't care if you only drive a
thousand miles or what, you still need to change it once a year and here's why,
when you burn gasoline which is nothing but hydrogen and carbon basically in
your car's engine Earth's atmosphere 79 percent nitrogen some oxygen and trace
elements waste product that comes out is carbon dioxide and water vapor, well the
water vapor makes water build up inside your engine and it will corrode your
engine, but say going on a highway 65 70 miles an hour fast hot then all that
water just boils vaporizes and leaves the engine, I see a lot of customers of mine
that don't drive much someone of them drive five six hundred miles
a year, and when I take off their oil cap
there's white stuff inside and that's combination of oil and water they don't
drive it enough to get that water out, so you want it with normal oil change your
oil three to five thousand miles or once a year.
if you got synthetic oil you can bump it to five to seven thousand miles
but still once a year, mechanic on Sunday I got a Civic with a 1.5 CVT, I hit the car
in neutral while I was running at 50 kilometers an hour and floored it,
I heard the engine screaming then put it back to drive do you think her damaged
anything in the engine or the transmission, well it didn't damage
anything in the transmission those CVT transmissions have various failsafe
things in them, so you can't damage it from what I've done research on most of
the CVT and realizes like 15 different varieties out there, but most of them are
set up so that even if you put it in reverse, say you're driving down a road
and you hit the shifter and it goes from drive to reverse you going 30 miles an hour,
it won't allow it to go into reverse because of the software and the way it
was designed, so you don't damage the transmission, but revving up real high
will damage your engine, they make great engines, odds are revving it up one time
didn't hurt anything, but don't make a practice of it, gardius 33 Scotty I purchased
an 05 Dodge Magnum two months ago it stalled on the highway,
I changed the plugs and sensor but it doesn't help, it won't start help, okay
well I got a video for that that you should start out with, it's called fixing
a car that cranks but doesn't start up watch that video gives all kinds of tips,
what you want to pray you said starting fluid doesn't make it start, so it can't
be just the fuel pump, if the fuel pump went out while you were on the road then
it died, when you sprayed starting fluid say take the air filter out and spray
starting fluid while someone cranks the engine, if it starts you know the fuel
pumps at least bad if not other things but you know that spraying it in makes
it run, since bringing it in doesn't make it run,
you either have an ignition problem or you got a serious problem like the
engine blew a head gasket or something, I don't advise people to buy 15 year old
Dodge and you get them it's the tail end of their life, I hope you didn't pay much
for it let's pray it's something like maybe a
crank sensor went bad, so it doesn't have any spark in that the engine hasn't gone
out, but it very well could be the engine going out I see that all the time,
nestle says Scotty I got an old 89 Suzuki Samurai, when first starting black
smokes coming out of the tailpipe, black smoke means it's running way too rich, if
it's carbureted you know, I don't know where you are all over the world some
places to live carburetors, if it's carbureted, the carburetors don't put too
much gas in the engine need you to replace it or rebuild it, but if it isn't,
and it's fuel injected and it's smoke and black like
that, the first thing you want to check is see if the fuel pressure regulator or
any of the injectors are leaking and a good way to test the injectors is this
you're getting black smoke it's a little bitty four cylinder, so take out the four
spark plugs and look at them and if one of them is black that injectors is bad and
spraying gas, but if all of them are black and they all gets too much fuel,
you always have to pinpoint why something's running rich and that's a
good way doing it because you got an old dinosaur it's an 89, you know it's obd
one you're not gonna get any good data if it was a newer car 96 or newer you'd
have obd2, and we mechanics can stick a scan tool and we can see all kinds of
data, but we can't on that old thing knowledge Sistani says what's the best cheap
scan tool that can read engine and enhance codes other than that blue
driver that you showed that plugs in and use your cell phone, there are lots of
scan tools out there, the problem is you want to read enhance codes to get any
serious enhanced codes and I mean serious, I personally like this actron
that I have but it's a 250 dollar scanner, it does a lot of enhanced codes
but it's 250 dollars and even that it only does it for certain vehicles,
enhance codes are high level information, you
need a high level scanner for that, when I'm really working on a car that has a
problem that say somebody's taken it to three mechanics they can't figure out
what's wrong with it.
the first thing I hook up is the scanner it's a five thousand
dollar scanner, then I start looking at the data and it's great because it's
color coded, good data is normal, bad data is red, and in between data is yellow, so
I look at all the yellow and red data and I can get a lot of information I
mean I got pages and pages to go through, first thing I do is look at the color
coded one and when I see color called ones that are bad I start there and
those things you're talking big bucks, that driver is pretty good but if you
want to spend 250 bucks you can get one of those actrons on Amazon the one
that cost about 250 they're pretty good, but if you don't want to spend more than
say 100 bucks, you're not gonna find much better than
that blue driver for that kind of oney, Bob aged 1970 hey Scotty you
claim that we're gonna cars for over 50 years that's a long time, so if you
started when you're 14 that'd make you almost 65 now, we don't
believe you, okay well I am 65, if you do what you love I have fun doing it
you're not gonna age, I'll give you a perfect example my grandfather was
working on cars when he was in his late 80s at my father's Texaco gas station
in Lewiston New York, friends of mine would come and they'd say, hey you know
your granddad boy he's still pretty shape, my granddad he retired a
few years ago and he's drooling on the floor and he could barely talk, I mean
he's gotten senile, well if you do stuff that you like it's
gonna keep your mind going, and part of the reason I answer all these questions
for people's because it keeps my mind sharp, I find if I don't do it, I start to
get a little fuzzy you got to keep exercising your mind it's just like
muscles if you don't exercise them guess what they go away, and even my
grandfather when my father said I'm sick of running a gas station and he shut it
down, well my grandfather that had no place to work within a year he was dead
he sat around on a couch watching football baseball games and hockey games
it was working that kept him alive and it's kind of what keeps me alive so, so if
you never want to miss another one of my new car repair videos, remember to ring
that Bell
