Here’s Why Honest Mechanics Won’t Fix This Car


rev up your engines today I’m gonna show
you how a diagnostic car that’s making noise when it’s running this Toyota was
making a noise for the customer whenever the car was running he said it send me
coming from the passenger front side by the engine here and that the car didn’t
have to be moving just sitting there idling there we’ll make it so we know
it’s not the wheel bearings or something the drivetrain cuz that’s not even
moving and he also said don’t when he turned on the AC one time when it was
raining and outside it made the noise a lot and the AC light
kept flashing on and off so that gives me a clue now on Toyotas if the AC
clutch acts up and doesn’t spin right spins and speed keeps changing the computer
knows that and will flash the light on and off so there’s got to be something
wrong with the way the fan belt is driving the air compressor and all the
other stuff inside there unfortunately this is typical for a lot of people you
brought it in here it’s not making a sound for me so what I’m gonna do is I
know it’s something a fan belt system so the first thing I’m gonna do is just
remove the fan belt and see what’s going on underneath it so there’s not much
working room here so I’m gonna Jack the car up and take off the passenger wheel
so we can access it better so up it goes and off comes the wheel there it goes and as you can see now we can access the fan belt and the pulley to see if anything’s
going on AC alternator belt we just loosen this bolt even though the one
down there top ones 14 millimeter huh that’s loose but the bottom on is an
absolute stinker it’s a 12 millimeter so I got this cool gear wrench with a
swiveling head so I can fit it on and loosen as you can see down here there’s
the wrench and it fits way down on the head there but that gives you enough room to loosen it once that’s loose you get a giant extension bar and a 12 millimeter cuz
the top way down there it’s got a hex then as you turn it it loosens the screw
so the alternator gets loose you just put your ratchet on it you gotta turn it
a whole bunch of times cuz it’s gonna move the whole
alternator there’s a lot of turning on this and as you can see now the fan belt is
are loose so we can take it off it away so we can get the whole fan belt I don’t
know what a lot of stuff in there so you gotta wiggle it reach down twist it so
each one there now it’s out of the way now we can spin the alternator it
spins freely in it doesn’t wobble back and forth and we’ll do the whole thing
down here with the AC compressor you can hear noise that means the bearing on the
AC compressor is starting to go out if you wanted to fix it you don’t have to
replace the air conditioning compressor now you could buy a bearing kit with a
clutch put it on a compressor but from my experience you replace just the AC
clutch and bearing they’re usually worn cuz the compressor is worn this cars got
like 260 thousand miles on it still has the original AC compressor if you’re
gonna fix this noise you’re gonna replace the whole compressor with clutch
assembly if you want it to be really fixed and if you look really closely at
the compressor down there you can see the edge of it here has a lot of grease
and melted rubber on it get my hand in there right here you can see that’s all
wrong with grease and kind of melted rubber not since winter starting as you
can see here the old fan belt starting to wear and just put another fan belt on
and tell them hey see what happens if the compressor finally goes out yeah
you’re gonna have to replace it but winter is coming on and as long as he’s
not using the compressor if the noise doesn’t come back hey you can live with
that because from my experience you should only put in brand-new air
conditioners in these Toyota’s the rebuilt ones not so hot but if
you’re gonna buy an OEM original compressor you spend a lot of money and it didn’t even make the noise for me when I was driving around so it’s
starting to go out and you never know sometimes put in a new
belt on that fits the grooves better that will quite it down for quite some time but
I’m assuming when summer comes in it’s a hundred degrees here in Houston again
it’s gonna need a new way see compressor and it’s not like he’s taking the car to
Californian back just a commuting car goes back and forth to work so if it
does break you can just bring it over here in our place the compressor and the
last time I saw one like this the compressor didn’t actually fail and
break the belt for like another two and a half years because as you consider
when I grab it you can hear a little bit of noise as I wobbled back and forth but
it’s not too bad it doesn’t have all that much play so I can still go a while
before it finally craps out so I’ll slip the new fan belt on and here’s a trick
you place it over the top first stick it over the alternator first then reach up
from the bottom and grab it it’s easier to get on that way then you can grab the
belt and start to push it around the bottom of the crank pulley it’s often
hard cuz the new belt of course is shorter than the old one get an
extension bar in a socket that fits on the end of the crank then you can put it
on here and as you turn the belt pops in place you pull hard nothing huh now the
belts over as you can see here it goes around all the pulleys now then you just
need to tighten that 12 millimeter bolt on the adjuster and a good way of
testing is this what’s good and tight the belt that belong around here will
twist about 45 degrees and it’s tight enough now this is an older car to 99 so
the belts adjustable are modern ones they have automatic tensioner you don’t
have to worry about it with these you want to get it with about a 45 degree
deflection then run the car about an hour then check it again because these
belts will stretch over time and if they do then you just retighten them after
they’ve run an hour or two so that they have about a 45 degree deflection or
they don’t make any squealing noises when you start up first thing telling
the other to loose then of course you tighten down the lockdown bolts and
don’t forget the one on the bottom where tensions it out of sight doesn’t mean
out of mind you want to get that one nice and tight too once you get it on
you can feel it with your finger to hold to tightening it down otherwise it’ll
slip out of the hole and you just keep turning until it’s tight it’s real
no filming room but there with my little wife there now you can see how it fits
on there’s hardly any working room but you could use your hands to feel it once
it’s on and then just tighten it till it’s tight but as long as you got it
jacked it up in here now we’re gonna start the car and watch it to see if anything
odd is going on and as you can see it’s not wobbling
it’s not making any noise so we just hope that that a/c compressor the
bearing holds up for a while longer like I said next summer the compressor will
probably go out eventually I have to replace the whole thing but really since
it’s not making any noise now hey the new belt might even stop it because the
old one was worn had worn edges and it was flopping around a little who knows
like I said I’ve seen somebody’s compressor bearings when they’re like
that they can go years before they finally go and realize here’s the
bizarre part when you turn the AC on then it no longer rides on that bearing
that’s clunking on the clutch then it actually spins the entire compressor and
it goes on the bearings that are inside the compressor it’s not the compressor
bearings that are making the noise the air-conditioning clutch bearings that
are making the noise so actually if you ran the AC all the time it might
actually last longer because then it’s not riding on the clutch bearings that
are worn it’s riding on the ones inside the compressor that aren’t making any
noise at all strange when you think about it this car would actually run
longer if you were in the air-conditioning all the time rather
than not turning on because eventually that clutch burning will let loosen the
belt to fly off and in the olden days it was no big deal because the air
conditioner had its own bell and you just wouldn’t have air conditioning but this
also runs the alternator so you got to have that working to drive the cars so
now you know how to check out noises in your car to see if it’s something
serious or something you might just live with for a while, so if you never want to
