we're gonna be changing out the

alternator on a 2005 Hyundai Tucson some

of our warning signs for some lights

coming on on the dash I think they kind

of spell a code out so we took it into

autozone had him run a diagnostic and it

definitely looks like the alternator I

went ahead and ordered one but then like

the day I ordered it that night we were

driving the car along and all of a

sudden like things started going dim

like a clock the dash lights and then

our headlights went out and then the car

pretty much died had had to tow it home

so that pretty much spelled out that it

was definitely the alternator so here we

are we're gonna change that sucker first

problem we ever saw these two lights

that break and the battery light were

coming on so that was sort of our

warning sign I didn't know what that was

looked it up turns out it's more serious

than a glitching panel it's actually

showing me that my alternate is probably

bi later these lights are right here t1

together while we were driving the ABS

brake and ESP off all right the first

thing we're gonna do is Jack the car up

so we can get that tire off front

passenger side tire you want the jacks

go right here on this this ridged part I

know it seems kind of weird because it's

thin but we just want the the jack to

come up on that how to jack stand ready

so we can have the car set down on that

all right so our goal is to lift the car

up high enough that we can get a little

free play under the tire a good thing to

do first and loosen your lug nuts before

you get the car off the ground okay so

like I said while that there's still

weight on the tire we're just gonna use

the tire iron that come that's in the

back of the car right where the spare

tire is

your Hyundai Tucson should have the jack

that comes with it it's by the spare

tire in the back not one's gonna give us

enough to get this off the ground don't

pick your jack right there there's like

some bolts there that are gonna make it

it won't sit flat

[Music]

okay so I've got a couple of Jack's

downs house I put my floor jack under

the front just the triple table backup

alright so I'm about to remove the tire

[Music]

thing a wheel chock like one of your

back tires okay so once we've got two

tire off this is what you see in here

first thing we're gonna have to remove

is this this plastic guard right there

the ten millimeter bolt they're round up

and around there's three more real quick

I'm just gonna go ahead and take off the

negative terminal of the battery that's

a ten millimeter okay so our next step

is to release tension on the tensioner

pulley so that we can get the belt off

of the alternator

there's the alternator right there

that's alternator pulley

there's the belt on it gonna belt my

bottom powers belt goes right up to

that's the tensioner pulley right there

and we're just gonna put the drive of

our ratchet in that square right there

we're just gonna crank down and pull

just to loosen the tension once you get

your ratchet in there you're gonna need

to pull with your right arm you get the

belt off alternator with your left

alright so now I've got the handle way

up high so I have some leverage it's not

as hard as I thought it would be do that

and I should all right so the pulley is

now off just okay so here's a top view

from inside the engine compartment and

next is to unhook wires there's three

different things you're gonna have to

unhook two of them rack of power

I think going in and out of the

alternator one of just like a wire wire

harness actually do that one first we'll

go under

right here there's just a little clip

that that harnesses this wire right

there I might already hadn't done but

you'll have to pull that clip out of

yours here's my new alternator which I

ordered from rockauto.com and just to

show you what you're gonna be working

with so this is where that the wire

harness thing plugs in I don't even know

how necessary that is cuz mine's been

broken that then there's a plug there

and then there's this this one will be

screwed on with a boot over it I finally

decided minute need more room for my arm

get in here so I took out this bolt I

think that's the power steering line

fluid line and that's just a bolt that

sort of anchors it I pulled that out so

I could push the power steering light

out of my way to get my hand back in

here cuz it's just barely enough room

once I could get my right on through

through here and then left hand up

through here then I can kind of get both

fingers on the plug and use my left hand

and my left index finger to push the

button on the back and then my right

hand just to jiggle it free it's really

hard it's not easy

you have two half-inch socket 13

millimeter fits two of a half-minute

seems to fit

I'm actually having a really hard time

getting my ratchet on that second wire

nut back there and so me I might be able

to when I pull the alternator out I

might be able to reach it better so I

might try about we alternate at first

and I kind of sliding it out we'll see

it so what I'm doing two main bolts that

hold the alternator and then the lower

one is right here and I just got 9/16 I

just took my ratchet on there and it's

really tight so I really wanted to use

my torque wrench that I have has a

really long handle on it so I can get

lots of leverage and so I'm just going

straight down three it's kind of a

wishbone shape to the up to the CV joint

anything I'm just going through there

and I was able to get enough torque to

break that one loose top bolt to the

alternators right there of course that

one's at twelve Mills there of it now

and there's some enough to use a wrench

least I have a ratcheting boxing range

[Music]

okay we actually have it lift it out all

right okay so it's still having a hard

time getting to that one electrical nut

on the backside of the alternator so now

I'm gonna try to actually pull the

alternator out damn like explaining this

hole just to be too small to get it

through things getting in the way is

this bracket right here that I'm like

again I think that's power steering line

and it's just a bracket that holds holds

it into there there's that 10 millimeter

bolt right there and if we pull that out

we can get this bracket out of our way

we've got that cracked off one of the

reasons I think this alternator went bad

is there's just stuff all over it which

i think is actually a power steering

fluid from the top of the engine now

with the alternator rotated I can see

that and that right there I'm gonna be

able to get the camera on it while I

undo it so this is the only way I was

able to write much work on it I don't

know like if you're doing this exactly

like me you might not have rotated it

the same way so just however you can get

[Music]

puzzle piece all right so I don't know

if you could see that but I pointed the

pulley out I pointed the polio through

this there we go you can just point the

pulley over the axle and then it comes

out of the wheel well you can tell this

alternator is just covered in grease

which I think may be dripping from the

power steering fluid I'll take a note of

this that wire post right there was a

twelve millimeter on the old one

and it's a half inch on the new one all

right so we are ready to install our new

alternator take this carriage bolt from

your old one mine was pretty grind up so

I just sprayed some degreaser on the

bolts and the nuts and you're just gonna

slide that one right through there

we'll go ahead and just lightly screw on

that nut we're not gonna tighten it down

or anything but we just want that to be

ready to slide down in that little

carriage arm inside there so we're just

gonna try to reverse how we took out the

other one with the plastic armature on

the backside toward the inside of the

engine and just going like this way so

your pulley is facing you before we get

it up in there go ahead and take this

nut off because that's gonna have to go

over the top of that the wire once we

slide it down on there and I'm gonna try

to position this first where I can

really get to that wire and I'm gonna

screw the wire down on I'm gonna try to

tighten that nut real good before I

situate the alternator in and tighten

down the bolts that hold it in

I think that's gonna help me get that

wire see this is from top that side of

it and that's where the wire comes down

I'll probably have to just blindly fuel

around to get it on the post okay

finally got the wire on the post so

right there this is the boot but I just

haven't reached him with my left hand

and like you can't see anything you just

had to feel it on to the post so you

have to get it no so it slides in and

they groove part here but now I just

need to get the net on and tighten it

down and then it needs to slide all the

way down so it makes the contact so I'm

just gonna actually show you on the old

alternator here see how this plastic

housing has grooves here and there on

the side so basically we're trying to

slide that wire on this post and get it

to touch flat down on that metal right

there it needs to make a good contact

and then tighten this nut good and snug

a tricky part though is gonna get that

to have the wire go in that groove there

because I don't have the alternator set

where it needs to go yet then after I

get that on then I'm gonna set it in

where it needs to go and then tighten

them okay so what I did is I just I

reached in and tightened just thumb

thumb screw the nut on just so that the

wire can't come off the post while we

move it around then I'm gonna situate

the alternator the way it's supposed to

go and then tighten it okay here's

another view from down through the wheel

well so see I position the alternator so

the pulleys facing out to me now and

what that did was that rotated the post

there such a way that the wires in the

correct place now so now when I tighten

the night

tighten it right now it means to was

able to get it I think sufficiently

tight on from here it looks like it's

making contact so I'm happy with that

now there's a boot that goes over and

just need to make sure that covers it

probably keeps up moisture okay next

step I'm showing you on the old

alternator

let's put this plug in remember this

part is facing toward the engine the

pulley is facing out towards where the

tire would be hit so the clip part of

this plug goes toward the engines I

might just have to feel around because

it's all on the back there's the right

side of the alternator just need to

sitting that little year there it's like

a cradle just reaching down blindly and

try to reach it and plug it and it's not

easy that you have a fuel-air until you

get it okay I finally got it um there's

not much room for that plug down there

so you actually have to kind of Palm the

alternator lift it up as far as it'll go

as you're plugging I'll share yo-yos

okay so here's actually how it's sitting

in the car and then sew around there

like that that's where we're trying to

plug it and so actually I got what I did

was I just took my hand and sort of palm

dinh then lifted it this way at the same

time I held the plug with these fingers

and pushed it in because behind the plug

there's not if this the alternator

sitting like that there's not going to

be enough room for the plugs

lift snap it in and that also lines up

this hole where that bolts going to go

[Music]

right there we're gonna let them we're

gonna line up those holes and stick that

bolt in tighten it and that was I

reaching from behind the axle and

everything I reached up through it

helped with my left hand

[Music]

that's bolt then with my right hand if

you want to you have to kind of hold the

alternator up against that arm and that

bracket right there

toward you and then line up the hole

because you want to make real sure you

don't strip out that bolt right there

and it should be able to thumb tighten

it all the way in or almost all the way

in because those it's really highly

machined threads in there and that will

help you know you're not cross threading

it okay so I was only able to find

torque specs 406 and newer two songs I'm

just gonna go ahead and assume it's the

same for the 2005 so that right there is

the pivot bolt and it says 14 to 18 foot

my own get that set burner torque wrench

alright that's a 9/16 everything got the

top or the bottom one's quite tightened

yes I'm gonna I'm gonna go up here and

tighten the top one just cuz the whole

thing is a little loose and wobbly

remember this one's a 12 millimeter and

you have a really tight space right here

to get in and so if you have these box

in ratchet wrenches man they're so nice

to get that would click there we go 14

to 16 on the lower one and 11 to 16

foot-pounds on this top one low light I

don't even think I can get my torque

wrench in there I have to have an

adapter and my drives to get it down the

fist

I might just tighten that one down just

hope it's close the next step is to get

the belt back and remember we just

popped our to drive on our ratchet into

onto this hold that down it's not too

hard just like that swing that down too

you get enough slack and then there we

go let off okay now I'm just gonna put

that bracket back on that goes right

here it's just like a mounting bracket

where you can hook the power steering

- Boehm - and that's a ten millimeter so

first we're gonna put the bolt down in

the bottom next we're gonna put this

little plastic guard back on remember

it's three well actually supposed to be

four bolts that go on there they're all

ten millimeter all right I can't

remember if I mentioned it in the video

I took off the engine cover just so I

could get better access to the side over

here and that's just four bolts that are

ten millimeter super easy slide that

back on those guys yeah good time to go

ahead and put the battery posts back on

and if you're like me you your car died

because the alternator crapped out on

you and you had to use up every last bit

of juice in battery to get back home

somehow

and in which case your battery is gonna

need to be jump something to say charge

it up to do that it's not gonna crash

right out all right now let's just get

our tire

[Music]

just a reminder when jumping cars you

want to park the cars next to each other

both first we're gonna attach the

positive jumper cable to the dead car

and then positive to the live car and

the negative to the live car negative

post and then the other end of the

negative on the dead car just attach it

to the frame somewhere and parked it

part of the frame then we're gonna start

a live car and let it sit for five

minutes and try to start

[Music]

the moment of truth the car started

right up let it run for a while that

really charged that battery up

disconnect your battery cables in office

then you hear how loud that car is that

turn next

the

you
