5 Secrets Only Car Mechanics Know

5 Secrets Only Car Mechanics Know


rev up your engine today I’m gonna show
you the forgotten maintenance items that
I’ve seen people over the years forget
to do and then it ended up costing them
a small fortune in many cases because
they didn’t do them now one of the most
forgotten things that’s easy to do is to
keep clean power steering fluid in your
car it lasts a long time but it’s a good
idea every four or five years to replace
because if you don’t you can end up like
this Honda van it’s a power steering
rack that’s leaking and broken as you
can see it is an insane job to replace
this thing because they built it by
putting a rack on then putting the
engine and transmission in the motor
mount on top of this power steering rack
now here’s the new one going on but as
you can see I got Jack’s all over the
place I got a jack up the engine the
transaxle and even had to drop the
subframe in the front down some to get
enough clearance all because the idiots
who designed it this is the bottom of
the back motor mount it goes over the
power steering rack and to get that off
you got to drop the subframe you got a
jack the engine and transmission around
it is a royal pain in the rear end the
power steering racks use power steering
fluid some of them are upwards of
fifteen hundred pounds per square inch
if the fluid gets dirty it becomes like
a cutting fluid high-pressure dirt
friction and it can cut through the
seals to make it leak all you need is a
turkey baster like this suck the
reservoir out tolls empty then pour in
power steering fluid in this case it’s
genuine Honda power steering fluid
Honda’s are very particular about what
they use you want to use Honda stuff and
Honda fill it up drive it around five
minutes then suck it out again to the
reservoir do that five or six times
you’ll get most of the fluid out and
it’ll be clean fluid because you don’t
want to have to replace a leaking power
steering rack because a dirty fluid
fluid doesn’t cost that much it’s an
easy job you can do yourself just do it
every four or five years or so if you
keep your car’s a long time now the next
thing that’s all forgotten is your air
filter
how does
saying go out of sight out of mind
air filters are hidden you don’t see
them but they get dirty I’m gonna get
dirty you don’t suck enough air in the
engine cars burn thousands and thousands
and thousands of square feet of air
burning gasoline if that filters clogged
up you’re not gonna suck enough air in
you’re gonna use more gas let’s go to
run poor too
quite a few times I’ve had customers
bring me cars cuz they failed the state
inspection and the only thing that kept
them from passing was a clogged air
filter when I took it out it was just
covered in black so check it every once
in a while if you live in an area where
it’s really dusty you can take it out
you can whack it on a bumper you can
suck it with a vacuum cleaner to get the
dirt out and use it over I’ll make sure
that you got it clean my advice is stick
a spare one in your truck just in case
you don’t want to wear your engine out
because you got a dirty air filter yes
you can’t see it it’s hidden away but
check it every once in a while
especially if you live in a dusty area
like we get these dust storms that blow
in from Africa here in Houston they got
a whole way over the Gulf come over here
they clog on my big time with little
particles of sand and Dawson so you want
to check your air filter yeah at least
once every five six months it’s no big
deal on most cars no nice forgotten
maintenance item is the cabin air filter
yes many cars have cabin air filters
this one’s hiding down in here it’s easy
to get to watch this will just squeeze
this squeeze that side it comes inside
here is the cabin air filter it’s just
gum top you take the cover off and you
pull it out and lo and behold it’s full
of crap and why is it full of crap
because Scotty’s been a bad boy he
doesn’t check it plus he parks owner
this tree Chinese Tree of Life those
little meals are always falling off and
they end up here so you can whack them
off later I’m gonna vacuum this off with
a shop vac get the crud out it’s a
charcoal one which filters better get
sort of smells and it’s really reusable
because you can keep cleaning and using
it over a lot of these companies charge
a fortune for these stupid little things
because it’s a cabinet your filter it’s
special probably cost a nickel to make
you think so you might just buy a can
and you can use it over and over again
and clean it versus buying a fifteen
twenty dollar paper one it’s gonna wear
out faster then you got to keep buying
them yeah these costs more but in the
long run you’re making out just make
sure you put them in the same way this
was the dirty part so it’s the top it
just slides inside this one’s a
different size each angle so you gotta
find the right one just make sure that
ends point it up down you get the clip
that fits in here and snap it in place
now the next maintenance item people
often forget about is your wiper blades
what am on forget about them when it
rains they use them and half the time
they won’t work you just need to clean
them every once in a while so that they
last longer and wipe right and it’s real
easy just got a glass with a little bit
of water in it then pour the same amount
of alcohol in there just about the same
amount pour it in there you go they got
a clean shop towel like this should I get
up below wipe it a bunch of times
look at all the crap that came off then
wipe all that off and you got a nice
clean blade it’s gonna last longer now I
used to use pure alcohol but I learned
my lesson I talked to a detailing expert
and he says you want to mix half water
and half alcohol the alcohol can
actually do too much damage to the
rubber on the blade well when you mix
them it cleans it and it doesn’t really
take off too much
so half water half alcohol and the next
forgotten thing is tire price you check
your tire pressure every once a while
cold first thing in the morning your car
is riding on air if you get low on air
you can have problems you where’s gas
smudge it’s dangerous you can get flat
you can get blowouts simple things get a
good gauge stick it in your glove box
and check it maybe once a month or
something in a ver now if you got a nail
or something’s going on just check on
baby want some wants it’s no big deal
but do it cold first thing in the
morning that’s the truest reading now
the next item is like beating a dead
horse but it’s got to be said change
your engine oil change it regularly
engines costs sometimes over ten
thousand dollars oil is a lot cheaper
friction will ruin your engine just make
sure you change it regularly and if you
don’t drive much change it once a year
I’ve got videos on the whole thing but
if you don’t do any maintenance on your
car except for one thing
change the engine oil and the same thing
is true ru transmission all if you have
an automatic transmission well you can
easily change the fluid yourself change
it every forty fifty thousand miles I
don’t care if they say it’s a lifetime
fluid now if you do have one of those
transmissions where it’s a real job to
change it pay a mechanic to change for
the little amount of money you pay to
change it you find out that a modern
computer controlled transmission I’ve
seen some of them cost five or six
thousand dollars to either rebuild or
replace with a rebuilt unit that your
trust was rebuilt correctly who knows
but you want to change that fluid to
just get a little book write it down
make sure that you’re not going to
forget this and your brakes they stopped
your car they saved you well do not even
think about them check them every once
in a while if they’re getting too thin
replace the pads you can see on these their
still really thick that’s the pad part
here that’s the backing and the rotors
that they squeeze sometimes it will warp
how do you check that it’s simple dived
on aha we’re going 65 when hardly
anybody’s around then firmly apply your
brakes if your steering wheel starts to
shake generally that means your rotors
are warped and it makes us doing a
little shake because it’s pushing in and
out it’s only a few thousands of an inch
but when you’re going 65 miles an hour
now if you find that you hit the brakes
and the steering wheel doesn’t shake but
the brake pedal pulsates that just means
that your rear rotors are warped and
they need replacing
if you got a really old car check the
rubber brake hoses if they’re starting
to crack and flake changing before it’s
too late now they’re well-made and they
can take a lot of pressure but when they
do start the crack before they start
leaking replace them if you look at them
and they’re all wet they definitely need
replacing now this thing’s got a little
surface for us cuz it came from up north
but the hose itself is fine
you see cracks or if it’s all wet from
leaking brake fluid change them out
right away no yeah I don’t know they
forgot maintenance item is the coolant
in your radiator if you keep your car a
long time you need to change your
coolant now let’s say you got a modern
Toyota it comes with the hope that can
last seven years or 150,000 miles so you
don’t have to change it all that often
but you keep them longer than that you
want to change them you can easily
change it out yourself it’s also better
to take out the thermostat and then you
can hose it through and get everything
out and then replace it with the longest
life coolant you can buy for your car
because then you won’t have to think
about a problem
ever again I mean if you got 150,000
coolant you changed it before 150,000, most cars are not gonna go 300 thousand
miles anyways read your car’s coolant to
make sure what yours has cuz there’s all
kinds of different ones out there now yes
most batteries these days are sealed
batteries like this you can’t add water
so you never have to worry about that
you want to check for corrosion if you
see corrosion on the terminals you want
to clean it off and in this case you can
see they’re naked there’s nothing under
the terminal what I advise getting those
green and red fiber washes that go under
there and they absorb the acid comes out
so it doesn’t corrode anything this
particular battery is so good it isn’t
leaking acid vapor so he hasn’t curled
it at all but most batteries are gonna
leak a little so if you put those little
washers on it’ll keep it from corroding
all your electronics because any
corrosion they’ll inhibit the voltage
flow that’ll cause problems a little
overheat stuff things want to work right
and of course batteries just wear out
over time so once every year to just
have a guy like me or a good auto parts
store check your battery it takes one
minute they just hook them up and turn
them on watch out faster test this it’s
a 640 cranking amp battery there we go
this is live in real time good bad or
it’s got 636 called cranking amps 100%
state of charge simple test everything
runs by computers your battery voltage
is low you can get all kinds of problems
the alternator can work too hard
it can cause shorts if the battery is
really shorting out if you smell sulfur
under the hood you know the battery
sulfate and it’s time for new one but
just checking every once in a while they
don’t last forever and you do need to
test them every so often so now you know
the most commonly forgotten simple
maintenance items that can keep your car
from having serious expensive problems
down the road with just a little of your
time and a tiny amount of your money, so

  2. I change my power steering fluid by removing the bottom hose from the reservoir. Let it drain into my catch pan, put the hose back and refill. I do this once a year and I have never had to replace a rack and pinion on any car I’ve owned. Cabin air filters I take them out, throw them away, and do not put a new one in. Brake fluid I change every two years.

  3. Scotty reminds me of a guy who was an "under the table mechanic" and lived in my area years ago. He was great at cars and honest , he was actually a preacher also my family used him all the time. He eventually just got too old to work on cars anymore and had to hang it up to everyone's dismay.

  4. Just had that one, a slow leak, little tree twig right through the tire – unrepairable. I keep pumping the tire up, but it keeps losing pressure. That awful, evil, over-priced-road-hazard warranty that I got suckered into paying for wayback-when-a-year-ago? Well? it just paid for itself, so I'm happy.

  5. For a complete Power Steering flush, follow the lines from the reservoir (after sucking out all the fluid from it) and unclip the low-pressure line (the one that doesn't have a crimp connection) and drain the fluid with the car jacked up, whilst turning the steering wheel all the way to each side and back. Once most of the fluid is flushed, use a little bit of new fluid to flush out any old fluid and particulate. Once everything is out, reconnect the hose, fill the system with fluid, and start the engine to get any air out of the system. I wouldn't recommend turning the steering wheel with the engine off as when I did this, the system overflowed and made a mess.
    Just be sure to have a drain pan ready and also some kind of hose or guide from the line to the pan. I made the mistake of not doing this and it made one heck of a mess. The car also used transmission fluid for power steering and it smelled horrible.

  6. Flushed tranny at change station, new tranny needed less than a week, 95' expl/expd sport. Tranny went again last year. Didn't even have to flush it again .. .

  8. I really like your videos, however I was surprised to see the battery unhooked with no mention of a memory saver! I think you should have mentioned this. Especially the newer vehicles that can loose a lot of memory by this. It could cost a pretty penny to reset the systems, depending on the vehicle. Good video, thanks Scotty

  9. Chinese Tree of Life! Scotty cracks me up big time. Imagine how much fun it would be hanging out with Scotty, getting all beered up, and talking smack! I'd be laughing so hard, I'd need an oxygen mask!

  10. Hi I have question if I use an smaller tire would damage my transmission or axles? I Have A 2002 outback 3.0 and I have a set of 205-55R16 that I Want to use Thank you for you time and videos

  11. I knew a few of these so that means I'm an actual Car Mechanic – Scotty Kilmer said so!! (I write software – including diagnostics – I do own a socket-set tho!)

    I'm getting new business cards tomorrow – "Scotty Kilmer Approved Car Mechanic" – I'm pumped!!

  12. My mechanic charged me $1200 to change my power steering rack and my power steering pump. He seems like an honest man but I don’t know about prices since I do a lot of things myself. Is that a reasonable price?

  13. Also when a light bulb fails remember to change also the one on other side because those things are engineered to last for many years fail in a very precise amount of time. And keep the still working one for emergency use

  14. Love your content Scotty. This is why I still argue that vetted older cars like BMWs and some Volvos that have bullet proof engines and good transmissions are better buys than Japanese cars for DIYers. You actually have room to work on the car without jacking the entire engine up. Just my opinion.

  15. I've seen a camery hit over 260xxx running strong it's definitally breaking records at 300xxx fingers crossed

  16. If i was a billionaire, I'd have Scotty help build a car so that it's easy to fix, with affordable parts, and designed specifically so that large components like this steering column can be easily repaired instead of ending up in a scrap yard or land fill.

  17. Secrets!!! I am not a mechanic, I am an engineer, and these secrets are common knowledge.
    The big secret is how he runs a business on his drive out of a junk filled shed!

  18. For domestic autos, vans, suvs, trucks, only, especially the older ones.

    Just buy a universal power steering filter and attach it to the return power steering hose / line, and replace it every year.

  19. Scotty where can I find the best monthly or yearly car maintenance checklist to keep me on schedule for a used vehicle? thx!

  20. You know I had a transmission done about 5 years ago complete rebuild $800 now I need the same kind of transmission done and now the job for just repairs in to go over it without a full rebuild is 1200 to 1800

  21. Those are great tips and I try to get to most of those areas on my vehicles each year and make sure the vehicles are working the way they are suppose to. Thanks for these tips and I hope you have a great weekend.

  22. Question, I have a 2015 Toyota Camry hybrid with almost 100,000 miles that takes synthetic oil….. it says in the service manual to do the oil changes every 10,000 miles but I’ve been doing them more like every 5,000-7,000 miles, is this a bad thing? Doing the oil change too often.

  23. O how I do love me some Scotty🤗such an intelligent, full of spark and most of all he knows wtf he's talking about..😏💚💚💚💚💚

  24. Buddy thank you so much for all the good advice!I had taken my car and my daughter's car to jiffy lubes to get her transmission fluid changed and my oil change I kind of got in an argument with the guy because all he wants to do is filter out my daughters oil and he charged me $150 that's what they also did to me as well in the past, they also wanted me to put synthetic oil in my car and I told him no and that was the main reason for argument. Is it true that it's not advisable to change the transmission fluid? I kept up the maintenance pretty good on my car.

  25. Thanks for all your help Scotty , you have helped millions over the years …I am from London and appreciate your videos some are very funny but all helpful .
    G T from London Wallington .
