rev up your engines, Christian Pete says I got a 06 Chevy HHR heard some GM vehicles
won't work right with aftermarket radios yeah you know it's true it's insane for
some reason a lot of the vehicles GM made it that the radio is part of the
anti-theft system part of the starting system of the car and I have had people
but aftermarket radios and the car once thought they told it to me and I
explained to them you know it's got the stupid interface for the starting system
I've also seen ones that they didn't even touch of it's a factory radio but
something broke inside it in the car wouldn't start
I don't know what this GM engineers have in their minds or snuck up their rear
ends but they're certainly not doing it right when they design stuff like that
that's just plain stupidity and they've done it, v6 rice burner says Scotty I heard
that if the ground straps to your engine is broken your wheel bearings can burn up
you know that sounds crazy but it's true you gotta have a good strap from your
negative terminal your battery to both the body of the car and the engine you
don't then ground its gonna seat you all kinds of sources and since the tires are
on the ground it can even go through the wheel bearings make them run hotter make
them burn out, so what you want to do is everyone so how did
you check your ground straps it's very simple they'll corrode it the battery clean
them or if they get loose tighten them up and then the other end they just bolt
on you can unbolt them see if they're rusted or corroded make them all shinny again
and then put them back on again it's an easy thing to do and it's often to
collect it on older cars people don't even think about it, James Royal the
first and he says I recently replaced the catalytic converter on my Chrysler and my
mechanic tells me the catalytic converter is
tripping a code that it's bad what could be wrong all right well the first thing is
it's a Chrysler unfortunately what people need to
understand about catalytic converters is they burn unburned hydrocarbons so you don't
pollute if a catalytic converter goes bad unless
you hear it rattling and it's physically broken into pieces of rattling around
inside there's something that made it go bad the engine is burning oil the engine is
running rich the engines running lean fuel injectors are dripping too much
fuel and that runs the catalytic converter or somebody was dumb enough to
spray silicone spray cleaner or using something like seafoam and pouring it
right in the gas tank and then it can mess with the catalytic converters they
go bad cuz there's a reason it hides out with yours you got a serious problem
master mechanic who said you need a catalytic converter again why is this
going on they don't generally go bad on their own unless I say they break and you
hear them rattling, there's a reason they go bad
and if you just replace the cat you'll just keep replacing and replacing, williams GMC
say if antifreeze gets into my engine and i
catch it in time do i have to replace all angeles if you catch up in time and
it did damage you thing you won't have to but here's what you have to worry
about your combustion chambers the piston goes up it's compressing air and
fuel spray so that compress is pretty good if you got a whole bunch of coolant
that leaked inside there when it goes up and it's tell us to go further if it's
pushing against coolant the valves are closed it still can push because the engines
got to spin it will bend the piston rods goodbye it'll run bad, so if you
find that it still runs good now and you change the oil and filter you're not
getting any foamy or a water mix yeah you could continue in a job you want to
pray that not too much got inside there, I'm at 9903 says my 07 hybrid
camry with 187 thousand miles is not getting as good gas mileage as it used
to okay it's a hybrid often that's the big giant battery the really expensive
one as they get older they lose percentage of the power and as they do
your gas mileage will go down I see that all the time in the hybrids now it is a
hybrid it's not a full electric car so you want to check the spark plugs on
your regular engine that's a gasoline four-stroke engine they are filled
there's stuff like that but if they're all ok and it runs perfectly fine odds
are your hybrid battery starting to wear out and then when you find the price of
that hybrid battery you might just live with a little bit worse gas mileage
Wilhemina j says, Ford f-150 I was going down the road and the speedometer
just stopped working and all kinds of lights came on all right you want to
pray that it's just the speed sensor there's an electronic speed sensor on a transmission
measures how it spins around sends an impulse to the dash and makes the
speedometer work now even though your speedometer looks like the old-fashioned
kind they have a speedometer cable it doesn't work that way the signal on a
transmission is digital and it goes to the dash and the dash changes the digital
one to a stepper motor and a motor turns it
so it's actually turning but it's not directly with the cable you want to pray
it's just that because if it isn't it could be something's broken in the
transmission and then you won't get a signal from the sensor praise the sensor
simple you can unbolt it by one and put on yourself too, very easy fix, Easy Rider
says Scotty why does the low oil light comes on
in a 2007 Express but it's full on the dipstick, knowing those things just change
the oil pressure sending unit they don't
cost much both off full time that could fix all your problems if that isn't the problem
then you basically want to go to a mechanic like me we put our actual oil
pressure gauge on that's a physical and it gives the actual pressure and if you
do have low oil pressure that can get super expensive it can be a bad oil
pump it could be bad bearings worn in the engine they'd have a bigger space so
oil takes up a bigger space that makes the pressure go down you want to pray
it's just the oil pressure sending unit from my experience on those it often is,
