Removing the Throttle Body.

[MonkiP1]

I thought I would post this guide as I recently took of my TB to be sent away for porting. And thought the community would benefit from knowing the proc for removing the TB.

So hear goes.

Firstly you need to remove the Intercooler to gain access to the throttle body.
You need to remove the two screws that hold the I/C in place.

Also you need to remove the clips for the DV, Re-Circ, the clips that hold the turbo to I/c pipe, and the little pipe from I/c to TB.

Once the I/C removed put it to a safe place.

Here is the pic looking into the inlet on the TB, this also shows all the components that are connected to the TB.
On the left is the ISCV and TPS sensors on the left, and two water pipes below the TB, and the throttle linkage on the right.

What you have to do now is remove the plugs that are connected to the ISCV and TPS sensors.

TPS

Here is a pic of both plugs connected and disconnected.

Now you need to dissconnect the throttle cable from the TB housing.
Undo the throttle cable at the bracket which is attached to the inlet manifold. There are 2x12mm nuts, Un-screw the nut closest to the Throttle body.

and push against the cable to free it up from the bracket.


Now you can remove the throttle cable by manovering the nipple away from the semi-circle linkage like so.

Now all you need to do is unscrew the 4x12mm bolts that are holding the TB to the manifold.

As you can see the bolts are now removed. and the TB is ready to come
away from the manifold.

Be CAREFULL when prising the TB away from the manifold, as you dont want to rip the gaskit, you can re-use it.

Sods law my gaskit was stuck to the TB so I very carefully and gently prised it off the TB like so.

As I looked over the gaskit sods law part of the gaskit decided to stay with the TB as you can see from the Picture I will need a new gaskit.

What you need to do now is the last stage of removal. You need to disconnect the two water pipes that run under the throttle body.

http://i69.photobucket.com/albums/i73/monki-boi/271120071085.jpg

And use a set of plires to prise the clips apart and then pull gently at the hose to take it off the TB. And use a 10mm or 12mm bolt to plug the hose to minimise spillage and loss of coolant.

Do the same with the other side as so.

One done you have done this you have the throttle body ready in your hands to be sent off.

Hope this guide has helped people who are not so knowledgable. And with thanks to PICKLE who talked me through how to disconnect the Tb ready to be sent off.

Kind Regards Monki.

Good one monki!!,a very help full and detailed guide.
Are you brave enough to remove the inlet manifold and send that off to marky mark at the same time,he does a pukka job

[MonkiP1]

Yeh piece of **** i think, :^o

But I know I would want to do a few more things while the manifold is off also and contribute to a few more guides :D

Good stuff Monki.

If you remove the manifold yourself and you get stuck please don't hacksaw it in half. :D
