All right we have a 2010 Lexus IS250 just changing the spark plugs and I'm
gonna do this video a little bit differently than I do my other ones, I
kind of wanted to show it apart and I know everyone likes to see how it comes
apart but you know what I figure some of these videos they don't really go into
detail you sort of see the guy telling you to take it apart but then you don't
really know what goes on in the middle and then it's sort of back together so
I'm just gonna try something different on this time so I've taken it apart what
you need to do is leave the throttle body attached so you're gonna leave the
throttle body here attached to the motor there's just two coolant hoses on it so
I can actually pick it up and I can move it around you can see the one coolant
hose right there and the one right there so there's just two cool hoses and you
can actually see if you go around there there's just four bolts and it pops
right off so that's it, the tube there that goes for the air filter I mean
hope you guys know how to take that off, that's quite easy and then
all the spark plugs on this side you can get to there very very easy just a 10mm
bolt you pull the coil up and change the spark plugs and I put anti-seize on
them, I know they come with them I put a little bit of extra anti-seize on them
and I put dielectric grease on the bottom of the coils when I'm putting it
in now this is what the intake or actually I think they call it a surge
manifold something like that Lexus calls it so if I can get a little better light
shed over on this side so I replaced the gaskets, they're quite easy to pop
out oh no it's that dark I wonder if I can get you a little bit
better like let's move it over up here there we go
so they're just little rings there they just pop out so I mean once again that's
easy as for the throttle body gasket if it's good you can just leave it it's
rubber and to be honest for the most time you can just leave these gaskets as
well I mean I don't want to give advice I guess everyone should say replace them
all the time but I find it's not really necessary here's a spark plugs that's
the hard side because this, I will call it the upper intake covers these so
here's the spark plugs here I know it's a little bit dark let's get a little bit
more light on there there you go, so they're they're quite easy now what's
important that they don't show you on most videos is how it looks when it's
all apart so this is where the plenum sits right there now if you look closely
you can see you have two studs there's one there and there's one right there
and if we count the bolt holes you can see there's one two three four five six
seven and eight at the very back there so we have eight bolts holding it down
in the center portion which is the center portion here we have another bolt
that's gonna go right in there that's kind of a tough thing I'm gonna shine
the light on it a little bit later to show you and then we have one right
there you can see there's a tab going up that one goes actually right to two
there and lastly there's one that holds a throttle body I'll show you at the end
I will show you that when you're putting together so you can see where those are
because I know it might be a little bit hard but the one thing on a lot of
videos like I said is they don't really show it all taken apart so this way I'm
figuring if a video isn't maybe explained
thorough enough for someone you can sort of show them what everything looks like
a part show them where are all the bolts are how many bolts there are to take off
and this way when you're taking something apart you can say wait a
minute I need so many bolts I need this I need that might be a little bit easier
to see these tubes are just vacuum hoses there's nothing
through them but top but air there nothing and then we just have lastly on
this side we just have the little it's just a fuel rail that
goes to the manifold and then a a connector there so pretty pretty easy
I'm just gonna show you one more time there it is here so let's flip it over
this is how it looks from the top you guys all all recognize it and then we're
just gonna place it down and then and then start bolting it up there is one
bolt it's tight to get out I'm going to show you when we're bolting it up and I
had to use a small little quarter drive so here it is right here and we're just
gonna lay it down just like that we're just gonna slide it slide it right in
I'll leave it loose and I'm gonna show you guys okay now I'm getting ready to
drop it on actually if I just rest it down like that I'm gonna back up you can
see there it is so you can see the throttle body connects right to there
just like that very easy four bolts there's the actual bracket for it and it
goes through the side once that lines up
this thing here like I said it's just two existing actually I'm just have it
less you can almost see it goes right there and then there's a couple little
electrical connections a cool line here that we're just gonna fish out of the
way as we go down now the one thing I did show you those two bolts that were
sticking up it's very easy to line it up and then drop it right down but there is
a few tricks and I want to show you guys just a few tricks a few things that I
found that really that really are helpful I'm just aiming a light here for
guys once you lift it up I hope you can see underneath it there's a wiring
harness at the back I'm gonna lift it up a bit there you can actually see the
clip and a zoom right in this little plastic tab there so there's
a wiring harness and I'm not going to be able to actually show you how I do it
cuz I'm just gonna reach behind it if you guys are doing the job you're gonna
know exactly what I'm talking about it's a great little wiring harness that snaps
to the back of it and then I'm gonna walk around just to show you guys again
I think I'm gonna move the light over
okay I move the light over to the other side so it's nice and easy to see so you
can see we've got the manifold there there's the actual clip you can see that
little hole there in it there's the clip it goes through when you're pulling it
off and be careful I just use a pair of needlenose pliers to get in there now
you look right down on the valve cover there's the port for the vacuum you look
on the cover there's a port there so before I drop it right down I'm just
gonna wiggle that into place and then you can see there's the this this
bracket on the rear of the head and it'll go into there there are a few
around goes so what I'm gonna do is I'm just gonna get it into place this thing
here are actually right here I'm gonna back up so you can see exactly what I'm
talking to look this thing here that hole there that'll be bolted right where
we I don't know if you can see it it's right in there so might be a little bit
difficult to see I don't know if it's my phone's picking it up I think it's in
there it's in the shadows but anyway you'll see as soon as it drops down
you'll see it'll line right up in there
okay so I've dropped it in place and you can see it's still loose
move it around pretty easy but you can see the two studs I was talking about
that one right there and now on right there they're lined up now so it's it
doesn't seem like anything is hitting nothing's binding you can see here if
you look down
I can show you this I'd like to show you this because these are sort of important
things that it's hard for people to do but I'm gonna pull the wiring harness if
I pull up I'm just gonna there you can see it moving right there that lines
right up with a head and then on this side right here there we go just a nice
thing there here here's your fuel line there you go just
like that and your fuel line just connects very very simple the electrical
connections easy to CV everything lines right back up I'm gonna walk around take
a look at this side we see our phone boards four bolt holes there for our
throttle body or throttle body's gonna back right up into it we see everything
lining up there nicely I'm actually you can see the marks where the holes is
where that black mark right there goes right in there
so everything looks pretty simple it's actually not a not a hard job to do it's
very simple I sort of wanted to show everything apart and just where
everything is just so you guys would see now the one thing I can say is if you
can see if there's a nut that will go on that these are bolts so you can see the
hole and if you look here they're they're allen head bolts now in all of
this the holes where they go you can get a 3/8 to drive into most of them except
the last one there's one where you can see down there it's the 3/8 one will fit
in there but then if we move back I don't even know how well I can get it
with my phone I think it's there you go right there that rear one you need to
have 3/8 is too big so you need a quarter drive so what I have for that
one I'm gonna show you a little tool just like this so what it is they're all
five millimeter bolts and what I have is just a little quarter Drive this is just
a quarter drive extension and it's a 5mm allen head on it so it's nice and thin
so it can get in there when I want to tighten it up now I haven't found that
works equatorial Ike that for it so what I'm gonna do with these is I paid
attention when I was taking everything out so I just snug them up a bit now if
you're not comfortable with that I know a lot of other cars are around 89 inch
pounds I'm not saying this one's 89 inch pounds at all but a lot of plastic top
manifolds seem to be around that torque value this one in particular like I says
the bolts came up quite easy the nuts for the hardest thing so start on the
center work your way out and just sort of snug them up you have to remember
it's just plastic there's not much to it and it's just rubber gaskets you're
compressing so there's nothing you don't really need a lot and and then the ears
on the side here where where it bolts to the rocker cover are showing you earlier
and the side that's actually what really gives it its support this more or less
just holds it in place in the middle bit and all the support comes from the side
not really from the center so you really don't need a lot of torque on it when
you're doing it okay so I got everything sort of snug down here on the motor so
everything's pretty good all the the bolts ring now one little trick there is
this part right in there and that's a little 10mm bolt now if
you put the throttle body on first it's really hard to get your hands in there
to get that bolt on or bolt back here actually I'm taking it up too when you
take it apart so what you do is you put the bolt in right now right there and
then and only after that do you take the
throttle body and then you just sort of sneak her back in there and it'll go
back on so that's pretty much almost about it
okay I had a little idea to what I'm gonna do is I'm gonna show you how I got
to each tight bolt this is something I've never really done before because I
assumed everyone sort of has their own ways but so let's just go through them
quickly so there's the one on the back right here and you can actually see a my
ratchet on it so that's the one in the very back I'm gonna back up so you can
see the car so that's the car we're gonna go forward
sorry if I'm giving anyone motion sickness and there's my ratchet so it's
tight now so what I'm gonna do is I'm gonna pull my ratchet out and then
you're you should be able to see the bolt just something different I'm kind
of trying we're gonna see this a little work
so yeah so the one at the back of the engine there you can see it yeah just
like that so now what I'm gonna do is I'm gonna take my ratchet out you can
barely see cuz my hands are down there
wonder if you can see the bolt, I don't know I'll have to see when I edit the
video later when I do some editing if it actually shows up that bolt don't know
so here's the tool that I used which is really handy it's 1/4inch, 12mm
and then this way you can go either way so it's really nice to get in there so
this is for this one and I'll go around and I'll show sorta because some of
these bolts are really tight so I'll just show you which tool I use to get in
there okay so going around in the back I showed you the tough one it's back
there next one is right in there and you should actually get a really good view
right there and all I did with with this one is I just used my my ratchet 3/8
drive ratchet 12mm on it and then all you got to do is you can actually
sneak it in it's on a swivel and you can see I'm actually tightening it up right
there and I'll give it a good snug up and that's how you get that one right
there and then we'll just go around I'll show you the rest
okay so this is the last bolt that I would consider a tuffy and it's you can
see I got it in there it attaches to the side of the throttle body right there
there it is and with that one it's actually quite simple with the before
like I said earlier before you put the throttle body in back up the lights you
can see the whole thing there we go before you put the throttle body and you
can actually reach in and just get it with your hand and then what I use the
tool for that is just a wrench there like that ratcheting wrench with a
swivel head just so it's easy to get on the angle so that's pretty much it those
are the hard ones I've put all the other bolts in there we go just tighten them
all down and then the one thing I did want to make maybe just a special note
of is the fuel line so for example when we
got the fuel line here I'm gonna have to get the light so you can see there
that's a good light, get it right okay so here we have
a fuel line connector it's not done up yet, it's right here
and here we have the bolt so I just want to make make sure that you remember (piece
dirt there on it there you go) just want to make sure you remember there's two
washers so one washer goes on the outside and one between so you have to
make sure you have a washer on both sides, so make sure when you put this fuel
line back in you don't have two washers on the one side there because it will
leak in the connection there that's pretty much it just zip up the
connections plug in the rest of it and that's it
