rev up your engines, mr master says I really wish I could know
what causes a battery overcharging in my car, batteries are charged by the alternator, your
alternator goes bad it can easily overcharge the battery, their called alternators cuz
they create alternating electricity actually, then they have diodes and the diodes turn
the alternating electricity into direct electricity, if those diodes start to go bad it can actually
put a bunch of alternating electricity, sometimes as high as 80-90 volts into the battery and
it will overcharge it and destroy it, now another thing that can do it is if you have
bad wiring or really dirty corroded terminals, those terminals are going to take a lot more
electricity to run through cuz their corroded, that creates heat, the alternator is going
to have to keep charging the battery at a higher rate it's going to get hot and it will
destroy your battery, so you want to check that too,
david orange says scotty what do you think about cabon cleaning snake oil or real fix,
if somebody actually has the equipment to carbon clean an engine correctly it's real
if your engine has carbon build up in it, there's no arguing that, no the real machines
cost an awful lot of money that do it, it's not a simple process and the chemicals have
to be just the right chemicals, anyone these days you can get a borescope and you can put
it on your cell phone on our laptop, I got a fancy one and I didn't buy it a company
gave it to me, I also have $15 ones that I bought on Amazon just to try out and they
actually work quite well on a laptop, you take out a spark plug and you can look around,
if you see there's a bunch of carbon on the valves yeah you have a professional carbon
cleaner with a machine that's pressurized you'll see a lot of it is gone, if you buy
good gas, change your oil a lot, and you look in with a borescope you might see there isn't
any carbon buildup so your wasting your time doing it, it doesn't need it then, bear says
scotty I got an 04 mitsubishi gallant 3.8 I have a check engine light come on, it's
for a thermostat issue but it comes off and on and a few days it's on and off, what could
be the issue, first just change the thermostat, thermostats are little devices that when the
engine is cold their closed, so the water stays in the engine to warm up the engine
faster, and then once they reach a certain temperature they open up, then the water goes
from the engine through the radiator and cools down, they are mechanical devices in most
cars, some of them actually have electronic ones which lead to a real headache when they
break down and replacing them, but most of them are mechanical and as many mechanical
thing it can stick, sometimes not open right, sometimes stick open, sometimes stick closed,
you got a code the first thing just replace the thermostat, that fixes it 99% of the time,
and if it doesn't then you can have a sensor problem, you can have a wiring problem and
even a computer problem but most of the time just replacing the thermostat and the gasket
will fix that problem, m1 lad, is an audi s8 5.2 l v10 engine a good
engine, well it depends on what you mean by good, their very interesting technology they
put out a lot of horsepower, but actually the engines themselves can last quite some
time, it's the rest of the vehicle that's more or less a problem in those, I'll give
you an example, I had a customer buy one of those used, it was wrecked and he thought,
oh I got a great deal, I got a wrecked one I'll fix it up and sell it, little did he
know that the aluminum frame is actually all bonded together with special types of polymer
stuff, basically the aluminum is glued together, then he found that he could never get it fixed
cuz they can't weld the aluminum and all the body guys said we're not touching that frame,
you'd have to repalce the whole frame, and of course that would cost so much money he
couldn't make money selling it on to somebody, so he thought, well it's got a good engine
I'll sell the engine, well who out there wants to buy just a v10 engine, not too many people,
so he got stuck with it and lost his shirt, lucas films says scotty I want to become a
mechanic I'm 17 years old, what do you think of a 1998 lexus es 300 I just got one, well
I got a 2002 es 300 for my wife she loves the car I mean their great cars, you want
to get into the mechanic business, it's a dirty business it's hard, your going to be
working your butt off in the very beginning, but if you like fixing things and today you
better like electronics, cuz electronics are where cars are going, electronics are getting
more and more complex, so if you like doing electronic work go ahead and get into it,
the thing is your better off doing like I did when my father ran a gas station and repair
shop and my grandfather was a mechanic there, I learned there, if you can find a place that
will let you go to school at night or something and they'll let you work kind of an internship
type thing, and train at the job that's the best way cuz from my experience a lot of these
training schools it's a waste of time, you pay them $20-30k and then when you're done
you end up getting a minimum wage job somewhere and you got to buy your own tools, your better
off doing it with a place that's actually fixing cars and learning while you work cuz
a lot of the training stuff it's bs as far as I'm concerned they got old equipment and
then you get some stupid little diploma that nobody cares about and your still going to
start at the bottom of the rung when your done, only your going to have a lot more money
out, instead of making money your paying money, so if you never want to miss another one of
my new car repair videos, remember to ring that bell!
