Pulling
the Engine
While
it is considerably easier to pull an engine with more than one person,
this page is derrived from
pulling
the engine by myself, so yes it can be done and I am not a spring chicken
so you young guys
have
an advantage.
So
you want to pull your engine for one reason or another. You will need some
equipment to do
this.
The equipment shouldn't put you in the poor house, but do not try and do
it without it.
Engine
Hoist (usually around $200 but also can rent one)
Floor
Jack
Jack
Stands, preferably 4 of them to raise the whole car to about 18" up.
3/8
drive Metric socket Set. Most used #10,12,14,17 but also need # 19
and
a 1/2" drive 30mm or 32mm socket for the Half Shaft nuts depending on model
year.
Set
of box wrenches covering #10,12,14,17
Pry
bar or crow bar.
Large
screwdriver.
1/2"
drive breaker bar.
Drain
pans: Suggest a large concrete mixing pan and a couple small plastic pans.
Possibly
some Liquid Wrench or Penetrating Spray.
Note:
WD40 is not a penetrating type spray and will help very little to loosen
bolts or nuts.
That
should get the job done.
Before
we start, let me advise you to replace all bolts or nuts where they came
from as you disassemble
or
with any component you may remove. It's a lot easier to locate and size
them later for reassembly.
As
with anything in taking it apart, you also need to keep some sort of organization
to your work or you
will
be at a loss when putting things back together.
To
start, remove the plenum completely. I will not detail this because most
or us ahve done it before
changing
spark plugs. Place a towel in the intake runner and a golf ball in the
rear turbo outlet.
Should
be without saying,, cover all acces to internal engine.
OK,
we can start in a couple different places but for this I will start with
the radiator.
Drain
the coolant system from the valve on the bottom drivers side of the radiator.
Open the fill cap to allow
air
intothe system so it will drain. This is where the concrete drain pan comes
in handy because small drain pans
are
just not large enough or cover any splashing or run off from frame members.
Unplug
all connections on the passengers side and the drivers side top end going
to fans and temp sensors.
Remove
the radiator side brackets.
Get
under the car. Oh, I forgot, jack up the car and put it on jack stands.
Remove
the underskirting or active aero in the front end.
Disconnect
the lower radiator hose.
Lift
out the radiator (it sits in rubber gromets and not bolted on the bottom)
The
followig photo should be where you are at. Note one of the rubber gromets
the radiator sits in.
Now
lets move over to the intake side.
Remove
the Y pipe, intercooler hoses, intake from filter to turbos, battery, battery
bracket, windshiled washer bottle,
Hoses,
vacuum lines and anything that connects the engine to the body whether
it be wiring, or hoses and get them
out
of the way near the side fender well or up above or near the firewall.
You should have it looking something like this.
Ok, yeah, you caught me,,
I hadn't removed the radiator yet in this one. Aren't tou lucky? You are
one step ahead of me.
Ok, moving back to the front you need to unbolt the alternator and the A/C unit. Here they are.
The alternator has one
top bolt and one botom bolt, but the electrical connection is not only
bolted on,
the electrical assembly
is also bolted on so if it doesn't want to unplug for you search for why.
This is also assuming
you have removed the fender well skirting and released the A/C and alternator
belt.
Once the alternator is
out oi\f there, ther are 4 bolts on the A/C compressor.
Remove them and lower
the A/C unit down to rest on the fram out of the way. This will also require
you to unbolt the top
rubber line from it's anchor near the cruise control box.
Should look something
like this.
DO NOT disconnect the
freon lines from the A/C unit unless you want a couple hundred dollar bill
to evacuate it and recharge
it later at the dealer or an authorized agent. There is no need to.
Ok, now moving to the drivers side unbolt the cruise box and swing it out of the way as shown below.
Ok, we are now done with
what's up top for now and need to disconnect the half shafts from the transaxle.
This is where we need
the 30mm or 32mm socket. Assuming we have removed the front wheels and
wheel
well, shrouding (gee
I assume a lot don't I) lets remove the cotter pin from the axle and remove
the nut.
Now lets move on to removing
the calipers and struts. Remove the two nuts front and back that
hold the
brake line and the anti-lock
brake cable. Compress the caliper a little with a screwdriver for ease
of removal.
Remove the two bolts
from the caliper and slide it off the rotor and hang/suspend it from the
fender
bracket which is why
we removed the skirting. This is shown in the below photo.
Now go up to the strut
connection to the lower unit and mark the top camber bolt before removal
as shown below
This is an important
part if you wish to avoid a front end alignment when you are done. Thats
is an excentric
washer and it adjusts
camber for the front wheels. Getting it back to where it was is important.
Once you remove the two
bolts, allow the assembly to drop and also while dropping tap the shaft
out of it's spline
and in tilting it to
the side, slide it out the rest of the way. The drivers side has a bracket
on the half shaft with two
bolts and locator pins
that bolt to the side of the motor. The drivers side also doesn't have
a keeper ring like
the passengers side does
and slides out of the transaxle much easier, however the braket must be
turned
a certain way to snake
it's way out of there. Here is a photo of the two bolts (partially replaced
and the two locator
pins from the half shaft
bracket mounted on the side of the engine. The bracket has to snake to
the left in between
the heat shield and the
rear turbo oil feed line shown.
The
passengers side is a little different. No bracket, but there is a keeper
ring on the end of the shaft that
goes
into the transaxle. I use a crow bar on the side of the transaxle to pop
it out of the transaxle.
As
shown by the photo below. Note to replacing: it must also be popped back
in.
Here is another photo of the shafts keeper ring.
For the sake of people
who I have seen say that we have equal lenght half shafts, for the heck
of it,
here is photo of
the half shafts next to each other.
The longer one is the
drivers side.
Ok, I am going to assume
again, that you removed your downpipe and hopefully you have read this
before
getting started because
you have to remove the downpipe in order to remove the bracket and half
shaft
on the drivers side.
On both sides this is about what you will look like in the process of removing the half shaft spline from the axle housing.
That said we are now going
to move on to the transfer case and the drive shaft concerns.
Please do not let your
drive shaft hang in mid air from it's universal sockets. Go get ourself
a bungie cord
or something and tie
it up to the frame. Here is a photo of mine after the transfer case has
been removed, but the
bungie cord was there
before removal. There will be some gear lube that will run out of the drive
shaft
spline, so be ready to
catch it and store the transfer case on it's end opposite the drive shaft
spline so the
gear lube doesn't run
out on you.
There is 5 bolts on the
transfer case. Make sure they are all removed before trying to pry it away
from
the transaxle. Here is
a good location to pry and work it back and forth till it comes off the
spline.
It's isn't all that heavy,
but don't let hit you in the face and keep the drive shaft end tipped up.
Store with the drive
shaft spline facing up.
Ok, we now have everything
disconnected from the engine hopefully aside from the power steering pump
which is near impossible
to remove because you can't get to the bolts. We won't worry about that
too quick
right now and move on
to the motor mount bolts.
It is now time to hook
the engine to the hoist as shown.
With no lift pressure
on the engine, remove the front and rear motor mount center bolts.
Now with light lift pressure,
remove the drivers side motor mount. If the engine starts dropping from
loosening the bolts,
apply a little more lift pressure till the bolts are not remaining tight
and the engine is
not dropping further.
Now using a ratchet strap
for the transaxle and using the hoist hook apply lift to the transaxle
till you are
able to remove the center
bolt from the passenger side motor mount as shown below.
In the wheel well of the
passengers side are 4 rubber gromets. Remove them to gain access to the
motor mount bolts for
the transaxle. Here is a photo. Once the center bolt is removed, remove
these,
Once they are removed
you have access to the transaxle mount bracket. This bracket shown below
must be
removed to allow the
engine to move over enough to facilitate removal. There are 3 #17 bolts
and
they are tough at times.
Best of luck there. As you can also see I have all the wiring off to the
side.
Heater core and vacuum
lines and other stuff is off to the left either up on the cowl or in the
space behind
the strut tower.
Once this is removed it
wil allow you to drop the engine down further than normal to get at the
power
steering lower bolt a
shown in the photo below.
Ok, that removed raise
the engine up to get at the top bolt. Yes, this is a pain, but easier than
trying to
get at it with the engine
in place. Here is a photo of the engine raised to get at the other bolt.
It is also easier to
remove if you also remove the tensioner bracket for the Power Steering
belt
which can also be barely
seen second pulley from right.
Also there is a wire to
the Power Steering pump on the top that comes from the engine wiring harness.
The engine is coming
out and the Power Steering unit staying behind, so it has to be unplugged.
Don't forget it.
Ok dudes, all that is
left is to go up up and away while pulling the engine back away from the
cowl.
You need the transaxle
strap to hold that end up somewhat for clearance of the front end and moving
it away
from the cowl at the
same time because of the pitch opf the hood if your engine hoist and your
chains
can't allow room.
The following photos
are of it coming up and out. Hope that makes things a little easier for
you in removing
yours. The up up and
away is easier with two people, same with going in because one can lift
while
the other maneuvers,
but with patience and a little more time, one person can do it.
Here's the finished product.
Additional fluid that came out during pull,, be ready for it.
Ready for transaxle removal.
