rev your engines today by popular demand I'm gonna talk about five noises that cars
can make how to find out what that noise is now to fix it we hear noises some
noises tend to drive us crazy so here's five of them they often drive people
nuts now the first one is when you turn your car's key to start it and how you
get is a click click click now that's a very common problem that has to do with
the starter when you turn the key to start it it activates the solenoid that
then pushes the bendex gear here out and when it goes out here then
it meshes with the flywheel on the engine and spins the engine by the
electric motor here turning and spinning it know when all you hear is a click
when you turn the starter and the car doesn't spin around that means you got a
problem can be more than one problem that's why you got to figure it out if
you have a battery that is low on electricity it has enough electricity to
make a little solenoid go click in but not enough electricity to make the motor
spin the engine first thing you do is try to jumpstart a car for jump-starts
great then you just know you need another battery if there's any problem
with the wiring you can do the same thing sometimes go and click when you
turn it be a loose battery terminal grab those terminals if you can where go
around take them off clean them and put them on
tight a lot of times you'll find it'll start right up again now if none of those
work then it's often a worn out started the motor won't spin because it's worn
out inside now the next common noise that occurs you turn your steering wheel
wire you're taking corners and in the front here click it click any click
clickety clickety click and then when you go straight the noise stops where
that clicking noise when you turn and drive is often a bad cv joint
you can see here here's a broken one you see the rubbers ripped the grease leaks
out and then this clacks cuz it's not lubricated anymore now that's very easy
to check you just jack up the car just enough so you can look under then turn
the wheel all the way so the tires as far as it goes
and just go under here and look there's the CV joint right here you can see this
one's not ripped it's completely all together well you see a trip like this
and the grease is all leaked out you know it's time for a new one and here's
a tip now years ago we mechanics used to take the drive shaft apart buy a new CV
joint and boot kit put it back together and put it on but these days there's
very good aftermarket brand new axle assemblies so you just buy a whole thing
and then instead of having to take it all apart and mess with all the bearings
you just take the old shaft out and put the new shaft in I got plenty of videos
showing you how to do it because if you're going to buy the dealer OEM
that'll often cost three times with the whole axle assemblies most places you
get an axle anywhere from 59 to 69 dollars brand new and they work
perfectly fine so there's no sense attempting to fix the old now the next
note you'll often hear is the squealing noise either when you start the car or
if you accelerate or if it's raining outside and it starts going and that's
often a bad fan belt yeah it shows my age they used to call them fan belts
because they drove the fan that cooled the radiator if you have a loose a
warrant and up it'll squeal when you start it up first thing before it warms
up in a loft and squeal when you accelerate because that's straining the
engine and then the belt or squeal or it'll often squeal hit rainwater rain
water hits it then the water makes it slip a little it'll squeals so here's
how you can tell what it is you can use some of the spray silicone lube and with
the engine turned off go to the fan belt area if you suspect that's where the
noise is coming from side of the fan belt like here you spray it all over up
and down on the inside yeah I was messing there but you just sprayed the
inside and spray the inside of the pulleys that drives over now spraying a
silicon spray isn't going to fix anything if it's squeaking and you spray it on
and you hear the squeak stops the belt is worn or it's loose and for my
experience today you best just to replace them because sure on my old 94
Celica the belts are manually adjustable as they where you have to loosen bolts
and then tighten them by moving the alternator then tighten them up and as
they where you got to retention them every once in a while but most modern
cars have automatic tensioner and most only have one
drive belt big giant thing so it's a good idea whatever starts to make a
noise just change the thing out especially if it's four or five years
old who wants to be stranded because of a stupid fan belt and here's another tip
don't go on buy the cheapest fan belt you can possibly get unless you go to
sell the car right away because the quality fan belts last longer I found in
the past I used to go and buy him at the dealer they lasted after the lungs but
now there's companies like Goodyear and many other ones out there that make
really good belts that lasts just as long if not even longer than the
original equipment but don't go buy the cheapest one if you go out of our store
and I said well we got this one belt for 1995 and the other ones 2995 by the 2995
one if it's got a quality brand name because you don't want it to wear these
things can last a long time I seen him last eighty ninety thousand miles so
when you do change it put a good one in so you don't have a problem neither
the next common noise is that you'll often hear while you're driving down the road and every
time you turn the steering wheel here that's inside the power steering system
it's making a noise because when you turn the wheel the power steering pump
has to send all its pressure to boost the opposite side that you're turning to
to push it harder to give you the power assist now sometimes it's as simple as
you just low on fluid it's not up to the top mark add some fluid if you losing
fluid there's either a leak somewhere or you just haven't checked it in a really
long time normally there's a leak but years ago my brother and I'll had a
Toyota van and he took it to the dealer and I said you need a power steering
pump we don't have it but with special order it and it was 500 something bucks
he hadn't checked the fluid in that thing for five six years they filled it
up so it was full when he drove away while he was waiting for them to get the
pump well they screwed up somewhere and he never got a call and the pump never
showed up but two years later it was still full and not making any night
overtime you could lose a tiny bit of fluid over years and years and years and
years it's off your lawn fluid and you fill up your lighter it's still pretty
full I wouldn't even worry about that but since they have so much pressure a
lot of these power steering pumps put out like 1500 pounds per square inch
pressures a lot of pressure normally the first thing to go is the high pressure
hose even my old celica had the high pressure
hose replaced it holds the highest pressure the rubber eventually falls
apart starts seeping through the cell walls or where it's crimped to the metal
ends at bolt-on it leaks there and that's generally really easy to figure
out wipe it with a rag and if it's a big leak and somebody turn the wheel while
you look out you see it squirting out you know that it needs a new high side
power steering hose and of course the pumps themselves can leak you'd look at
the front where the pulley is that's the front main seal and they can go bad
they'll be leaking out of the front i'm the worst case scenario is that you have
a leaking power steering rack when they leak the fluid will drip at the end of
the rack where the boot is they've got a big rubber boot and the fluids coming
out of there that means that the rack is gonna have to be replaced because that
big rubber boot that's on the end of the power steering rack on the left hand and
the right hand that's just a dust cover to keep dirt from getting inside the
actual seal is inside the rack itself so if there's fluid leaking out around that
outside big rubber band that you see it's too late that's not meant to seal
fluid pressure that's just to keep dirt from getting inside and wearing a seal
then you'd have to get a new wreck and they're very very expensive and in
probably the rarest of cases older honda accords i've replaced power steering pumps
on many of them they made to me as you turn into car but they had no leaks and
weren't losing any fluid and it was just that the pumps were out made that noise
Honda's just over the ages had problems with their pumps wearing out prematurely
then they make a lot of noise when you turn and here's a warning about power
steering pumps if you are planning on replacing your power steering pump
please use a brand new one don't use a rebuild one your rebuilt ones are often
terrible garbage I used to try them for customers half the time they either
wouldn't work they bind even worse than the previous one did or they made a lot
of noise and I've had them when I took aback places and say hey this pumps too
noisy and say look we guarantee that it works
and that it doesn't leak but we don't guarantee that it doesn't make noise or
if you want to gamble with the better gamble than a rebuild go to a salvage
yard because hey there's only lasts a really long time and a lot of times you
can pick up a used one for 50 bucks and it'll work perfectly fine the last thing
I'm gonna talk about it noises in your car your cars run you hear a ticking
sound and it doesn't matter if the cars running driving moving as long as the
engines running you hear a ticking sound well you want to pray that that ticking
sound is something like a worn fuel injector so if you use a giant
screwdriver like this or any metal when the cars running all you have to do is
put it against your and check the fuel injectors one at a time with your ear
put it on the base of the fuel injector or lessen your that ticking loud when
you get on one of them you know it's the fuel injector that's clicking and of
course the double check that when it is running
if you suspect say the number three injectors making a noise
turn the car off unplug that injector and start it up it'll run poorly but if
you hear the ticking goes away you know it's the fuel injector now you want to
pray it that because if it isn't and when you put your sounding unit on the
actual engine on the head itself or the block and you hear the tick and then
odds are you got a serious internal engine problem like a worn bell bad
hydraulic lifter or you got the rod starting to knock because the bearings
are wearing out that you don't want but of course a fan belt or any of the
accessories that it drives sometimes they can tick if bearings go bad before you
get rid of your engine remove all the fan belts then start it up and pray that the
noise goes away because then if the ticking goes away you know it's
something that the fan belt drives a bad alternator bearing bed water pump
bearing bed are you learn bearing something besides the engine you do not
want to hear ticking noise coming from your engine if you do then you're gonna
have a really bad day so now you know some of the most common noises your car
can make and what you can do about it to fix it so they don't drive you nuts anymore
