rev up your engines 13 says Scotty what do you think of the 99 mercedes-benz G 500
Cabriolet were they still reliable at that time well they were when they
were new but realize you're talking about a 21 year old Mercedes with a v8
engine and those are all money pits as they age the parts cost a fortune the
rubber starts to deteriorate the plastics start deteriorate they're just
endless money pits now every once in a while it's a convertible so you're like
I feel like convertibles I got a customer once a while that'll buy one
cheap and it's a weekend toy I got one guy and he bought one and he takes his
girlfriend out with it on weekends and he just stores it in the garage the rest
of the week and I think last year he put 2,000 miles on it or something and
you want to gamble with dynamite what the heck maybe I'd be a cheap fun toy
they're not a reliable thing you can drive every day when they're that old
with the Mercedes v8 engine they're just endless money pits Plus realize the old
thing like that was good gas hogs you're gonna spend a fortune in gasoline if you
do drive it every day for thousands and thousands and thousands of miles it's
not a smart thing to get as an everyday driver
Anthony Hatfield said what do you think about old used Bentley's found in 1988
Bentley Brooklands 40,000 miles for 12 grand on the older ones simpler to work
on you know it's not simple simple realize that those are all endless money
pit cars to begin with their English rolls-royce Bentley they made a
lot of crap their stuff just fell about I remembered reading back in those they
said some guy what a rolls-royce in some contests and when he was taking it to a
car wash the whole exhaust system fell off on the ground it was so poorly made
now if you really want one of those have a mechanic like me at least road test
and check it out to see what kind of shape the thing is in and if it isn't
completely falling apart you want a weekend toy and you got 12 grand you can
throw away go ahead but realize you can't buy a car
like that driving every day fifteen twenty thousand miles a year it will
bankrupt you plus getting parts for a Bentley if you're in the United States
hoo-wee assuming you earned in England cuz you
wouldn't have said $12,000 and you would have said pound so how just realize it's
a toy if you want to spend that much money on a toy and the guy says it's okay go
ahead but keep it as a toy they are money pits there's no arguing that
72 Nova says what causes vapor lock in a car very good question vapor lock is
when the gas somehow between the gas tank and your engine is vaporizing
inside the fuel line then the pumps that are in your car are made to pump liquids
now when I was a kid that would happen a lot because what they had was you had a
gas tank in the back and then you just had a line that went to the front the
bottom of the engine was a mechanical fuel pump that every time the engine
spun would go pump pump pump pump like one of those old water pumps right the
line got too hot the line would vaporize and when that vapor got to that
mechanical pump it can't pump it you get a vapor lock and the car wouldn't run
modern cars it's virtually impossible to get a vapor lock in because the pump is
inside the gas tank it's soaked in liquid gasoline it can't get any vapor
in there unless you run out of gasoline and then you got a problem there's no
gas in the tanker that's why it's not working so modern cars that's not
something you really have to worry about but the old ones would because they had
a mechanical pump and even if they had an electric pump in the front it get hot
enough under the hood the heat of the engine that before that electric pump if
that gas vaporized in a line the pump would get it and it stopped pumping but
almost all cars now have the fuel pump in the gas tank so you can't get vapor
lock because they're pumping liquid the whole time oh cool that is vapor pump
can't pump vapor can only pump liquid least the ones that are in cars
John John says I'm following you from an Afghan cave which armored car is good
well you got pretty good dog oil is going on there if you can send me a
message from Afghanistan you know my son had two tours of duty there guys that
want armored cars you're pretty much getting a good diesel and have that done
cuz it's gonna have an awful lot of weight in it and the diesel engine has
more torque so it can pull that heavy weight around so you'd want something
that was diesel power that can pull all that weight cuz the true armored car is
gonna weigh a ton that was the problem with tanks in World War two the Germans
were making these huge tanks but they weighed so much and they put the biggest
engines he could find in him that came out of airplanes and they still gonna
let go like eight miles an hour the big giant ones so you have a big
strong diesel engine if you want an armored car just beasts inside my first
winter car with a car on painted rims is it better to run steel rims with my snow
tires it's such a pain swapping them they'll just get plain steel tires for
the winter and then put their good tires on in the summer because the salt is
gonna destroy your fancy rims overtime feel it up north so they throw a lot of
the salt on the roads and stuff like that you don't want that to happen
you're probably better go to a junkyard or something buy plain old steel rims
and put your snow tires on it and if you want put fancy hubcaps on them so they
look better or whatever it's a lot easier already having your snow tires on
separate rims then you can just storm in your garage and then put them out in the
winter yourself and study having to pay people to my own them
dismount up really balance on them and all that stuff it's a lot of work
George Wilson says I got an 03 Ford Escape the alternator keeps going up one
where are you buying the alternators if you're buying the cheapest rebuilt you
can get that we rebuilt in Mexico or China that's after your problem now if
it's not the alternator itself it's that it's being strained you want to have the
battery law tested a weak battery will eat up alternators and the wiring wires
have to be clean the connectors have to be clean bolted on tighten any plug in
connector has to be perfectly clean because if there's corrosion on any of
the electrical wiring where the either bolt on or snap in that creates
resistance the more resistance you have that builds up heat that heat what do
you think it does the heat shorts out the alternator cuz it's working too hard
it's making it heat up itself and burn things up so unless you're buying the
cheapest alternator you can get your hands on you got a wiring short
somewhere and that's typical especially on those Fords a lot of times I tell
people just change both battery cable assemblies and it usually goes away cuz
Ford's a notorious as they age that the internal parts of the battery cable
start shorting out start having problems I see that all the time Turner has
knowledge says any advice for door ding repair thanks Scotty you know you could
try it yourself but I tried and I gave up I do not have the patience the job to
do that stuff there are guys out there they're called paintless dent removal I
got a video on it you can watch it on YouTube guy did one heck of a job
taking these dings out of my wife's fender when some
bashed into it in the parking lot but he spent two and a half hours doing it I would not have the
patience they got special little tools these paintless dent removal guys and
they hit them they hit them they got a heat lamp and then he had a giant mirror
that had graduated scale so he could see when the lines were straight and like I
say two and a half hours to take those things out and it looked beautiful but
ironically enough but somebody smashed into the same thunder two years later in
a Walmart parking lot destroyed the whole thing I took it at my body shop
and he had to put old fender I'm gonna paint it so irony abounds here Tim D
says you've been a mechanic since you were 10 years old no I've been a mechanic since
I was 14 years old they didn't have child labor laws back then I've been working on a car
since that's when I was 14 I started working at my father's gas station with
my grandfather on weekends my grandfather was a mechanic so I learned
how to fix cars from him he would work he was one of the few mechanics that
would work on Saturdays and Sundays where nobody else did and went to the
racetrack he liked betting on the ponies he liked horse drag racing so 14 I
didn't start when I was ten I mean I was messing around with stuff when I was 10
I take things apart put him back together again they didn't often work
then but once I learned from my grandfather I
could take them apart and put them together and they'd still work accor
B says I got a friend that has an 02 acura TL 3.2 with 269 thousand
kilometers he hasn't driven since Sunday white smoke comes from the exhaust and smells
like gas the check engine light is on their notorious when they get that age a
blowing head gaskets so the first thing you want to do how to tell if your head
gasket is blowing if you don't want to pay a mechanic a little test tube
testing kit you get them on Amazon for like 30 bucks simple test to do when the
engine is called you just take the radiator cap off put the test tube on
pour a little the boom fluid so it's like about a third of the way there's a
line start the car the blue turns to yellow
you got a blown head gasket you might not want to fix fixing a head gasket on
one of those v6 engines is gonna hit you back anywhere from 1500 to 3500 dollars
or even more if there's real serious engine damage inside so most guys don't
wanna do and I pray that test is negative let's say the test is negative
you don't blow a head gasket then check for like a leaking fuel
injector because if a fuel injector leads to much fuel you're gonna get
white smoke cuz there's too much fuel and the white smoke comes out from too
much fuel get them the exhaust prey it's that I know it's not a blown head gasket
but you gotta do the blown head gasket test first cuz it's simple it tells you
right off the bat then you want to spend a bunch of money you just get rid of it
peanut head Siegel says code p0172 fuel system rich on the
2010 chevy malibu 2.4 flex fuel what could be the problem
i know lost things inside out cuz they're always breaking so I'm always
working on them pay off and they have a problem high pressure fuel pump they're
leaking and fuel gets in check that first that's a known flaw I don't know
if they recalled it for your model some of the models they actually had to recall
they were so bad that's almost always if I press a fuel pump but any kind of fuel
leak can do that you could have a fuel injector that's starting to leak you can
have a sensor that's wrong that's giving wrong damage to the computer so then
it's praised in which gas said but for my experience with those are almost always
the high pressure fuel pump because it puts out so much pressure and
they built them poorly on the GM pratical what a surprise GM making
something poorly I see that so much it's makes my head spin that's why I'd never
drive one these days myself I don't even rent them when I rent cars I say no no no
I don't want a GM product I said you know I'll take a kia they usually work ok or
you know even a Nissan but not a GM product I don't trust them stand you by
the side of the road even when they're late-model ones and a car rental place
so if you never want to miss another one of my new car repair videos, remember
to ring that Bell
