rev up your engines, riki Cunningham says, what would cause my
headlights to go brighter when disconnecting the negative battery, never
do that in any modern cars, you can't leave a car running in a modern car and
disconnect either battery terminal, you can get voltage surges that will ruin
all the computer modules and it's not like you only have one computer module
the average car today has like 40 modules, some
Mercedes have 97 or over a hundred separate modules you never want to do
that, and if they get brighter either you've got a crappy battery and it's
using so much electricity up from the alternator that when you remove the
cable and take the battery out of the whole equation, the lights will get
brighter, also go out and have your alternator load tested you can have an
alternate putting out actually too much voltage, that's what people don't
understand alternators are called alternators because they make
alternating electricity, then they have diodes in them that turn that to direct
electricity, if those diodes brake you can actually get an alternator that puts 100
something volts out and it'll fry your whole car, so get that tested too just to be on
the safe side intro tainment says can low
antifreeze coolant affect your transmission, well yes it can indirectly
and here's how, modern cars your driving down the road,
you got a radiator but either in the bottom of the radiator or on the side of
the radiator like on GM's, there's a coolant tank that has transmission fluid
that goes through it, your radiator also cools your transmission fluid it gets
hot, so if you're low on radiator fluid and your car starts running hotter it's
gonna make your transmission run hotter too I even had the exact opposite
happened with a customer didn't know they towed a Subaru from Austin to Houston,
that's like hundred seventy-five miles with all four wheels on the ground, and
it ended up blowing the head gasket of the engine, even though the car wasn't
running they were towing it and all that
spinning of the transmission with nothing working, and made the cooler on the radiator
for the transmission get so hot it actually bubbled the coolant out of the
radiator and overheated the car, and it wasn't even running, so you can go the
other way too, john madden says is it ok to grind the ears of brake pads to make
them fit, you want to get the right ones really, now in a pinch I used to do it
years ago, I was a mobile mechanic and I went around fixing cars at people's
homes and offices too, if I got brake pads and it was just a little bit off,
I'd be cursed if I was gonna go drive 20 miles to get pads that are right again,
and I would I had a grinder and I would grind down it so they fit in, you could if
you do a really good job, just gonna make sure you do a really good job, you're
really better off buying the correct pads, I mean if you want to go tiny bits
by tiny bits then you get them in there go right ahead,
but be careful cuz if they're too tight they'll drag and if their too loose you're
not gonna like because every time you hit the brake you'll hear click as
the whole assembly moves a little bit won't hurt anything it will just be
noisy and then it will probably annoy you Fernandez says Scotty what are
your thoughts on a 66 Ford Econoline thanks, I rebuilt an engine one of
those things for a friend when I was a kid in the late sixties, those were
cool old Vans and I mean they were turds speed wise, this one had 170 cubic
inch straight six-cylinder and a three-speed transmission on the tree, it
could barely get out of its own way, but I mean he had a waterbed in the back you
know, then sleeping in their vans, they were solid built you can still get parts
for the things, I mean they're very basic machines, carbureted so if the carburetor
goes bad put a new carburetor on it
everything still available and if you like it, yeah why not, the one caveat I
have on any of those old things are, don't buy one if the frame is all rotted because
if the frame is rotten it's useless it'll just fall apart, but check the frame
first if you're thinking about buying one, reese says how do you fix an LCD
satellite navigation screen on a Ford Focus, nobody fixes those things, go to a
junkyard buy used one, what most people do these days they'll just throw the factory
one away and put in an aftermarket Android, I
got a video on that I put one of these aftermarket androids a company sent me
I thought I'd try it out and it's fantastic I mean I got all kinds of
music on the little micro SD card and videos whatever you want, you can play
whatever music you want and they interact really well with your phone and
get my samsung phone if we're going someplace and I can go to Spotify they
can play all my music through that Android and here's the weird thing, when I
put that Android in I kept the speakers that the Toyota came with, and I thought
man the stereo that Toyota put in this matrix is pretty crappy it didn't sound
that good, well when I put that Android in and it was
only a $300 android, man the music sounded better, it sounds fantastic when
you turn it up and I had the same old 10 year old Toyota factory speakers and so
I didn't bother changing them, sounded so much
better, and that was only a $300 one, who knows what the really expensive ones sound
like, but I'm too cheap to get those anyways, so if you never want to miss
another one of my new car repair videos, remember to ring that Bell!
