rev up your engines, Omar says Scotty my ac is leaking
somewhere in the system, will a stop leak product work to fix it, I never advise
using stop leaks in air conditioning systems for one main reason, they have
very tight tolerances and if you put a stop leak in, I have seen the AC
compressors lock up, and I had one customer a few years back, they put it in
their Mercedes, now the problem with their Mercedes was, it was leaking inside
the dash, and to take the dash apart on this particular Mercedes was like an
$1,800 job, so he thought I'll put a stop leak in, well he put it in, and it stopped
up the expansion valve that's inside the dash, then he had to take the dash apart
to fix it, because it didn't work at all and it
built the pressure up because the expansion valve got stuck shut, an
expansion valve is a little needle and it goes up and down, and when that thing
gets stuck in that little hole, boom it's the end, so I don't advise using sealers
in air conditioning system at all, now some of the sealers for cooling systems
they're okay, they got reasonably big gaps and
some of those can work okay
in a clean coolant, but for an air conditioning system don't mess around
with sealers really, wolf says Scotty is it ok to block
the EGR pros and cons, the only thing the EGR valve is made to do, is to stop pollution
that comes out of your tailpipe which is a pollutant it's actually cancerous, when
I was a kid cars didn't have EGR valves and when they first came out they didn't
work all that well, so a lot of guys did block them up, and of course the car will
actually run better without it, but you're breaking federal law your car is going
to pollute more, that's the reason that they're in there, now the thing about EGR
valves is, a lot of modern cars they don't even have them, because the computer
control of ignition systems, of fuel injection systems, their all so good now
that they can do it themselves without an EGR valve, so a lot of modern cars
don't even have them anymore, David says hey Scotty what's your
thoughts on a 2013 Subaru Impreza for $10,000, Subarus can be good cars where
it snows, they've always had a history of weak automatic transmissions, if
you're gonna get a Subaru get a standard transmission, the customers that I have a
Subaru with standard transmission some of them have 200-300,000 miles of
relatively trouble-free driving, their well made, there's nothing wrong with them,
but their automatic transmissions are weak, I
rented one a year ago, brand new one, well it had 14,000 miles on it, and
it was an automatic transmission and it had already started to shift weird when we
were driving around Utah when we rented it once we got off the plane, so I'm not
impressed by their automatic transmissions at all, gonzo says what can
cause my speedometer to read 15 miles an hour faster than its going in a 95 Chevy
truck, well if you put the wrong size wheels on it, it can give you a bad
reading, and that's what happens all the time, a lot of guys don't realize it's
gonna do a lot of things, a lot of times as they age things wear or someone
mistakenly, I don't know if you probably didn't own it since new, put the wrong
speedometer gear inside the transmission, and if you have one that
has different teeths, it's gonna give you different reading, so if it has the
stock sized tires check that, the sensor could have the wrong size speedometer
gear on it, I've seen that happen, especially if your not the original owner
it's been messed with, you'd have no idea what anybody's done to it, and I've seen
people go to a store and it's not their fault
somebody sells them the wrong one and they put it in and then they say, oh well
it's working and it's off, I don't care I'll just remember, Vincent says my power
steering makes a cranking noise when the steering is all the way turned, any idea
what could be wrong, is it the fluid that's bad, well you can check the fluid
see if it's low or anything, but generally it's not that, if it only does it
when you get to the edges, as far as you go, and you did say turning it all
the way, then it's generally a slightly worn suspension part some, tie rod or
bad ball joint, when you turn it all the way it's pushing as hard as it can at
the edge and it'll make a noise, or if something like your strut mount is worn
when you turn it all the way it could be it gets to the edge and then it makes a
clang, so Jack it up and
check for any worn parts on the suspension first, Ollaf says
scotty my interior light flashes sometimes when I hit bumps, what could be
the problem, if you hit bumps and a light start to flash
generally it's an electrical short somewhere, if you're talking about the
light isn't even on, and then you hit bumps and it comes on, check all the door
switches, because one of them is probably breaking down and when it hits a bump
its closing the circuit and making power going, making the lights go on, now if
you're talking about your dash lights that you hit bumps and then they start
flashing on and off, then you got a short in the dash wiring somewhere, on those
there's a lot of little tiny wires on those connectors that plug into the dash
take it apart, see if any of them are corroded or loose, or if the ground wire
is going bad, that will often happen if it's the inside lights in the dash that
are doing it, so if you never want to miss another one of my new car repair
videos, remember to ring that Bell!
