I'm just about to remover the alternator from my 4.5
Do the throttle bodies have to come off to pull it out of will it go out the from where the air con pump is?

I have already removed the Air con pump from something previous.. it looks like the alternator will go through but the tensioner bracket is in the way. The bracket seems to be held in too solid so am guessing its held in place my more than two bolts.

No idea on the 4.5 but from the inlets down it is the same as the 4.2 ,I had to remove my inlets to lift it out.

The bracket is held down by 4 bolts and the alternator is fixed to the bracket by 2 bolts.
I replaced mine last year

Are two of the bolts for the bracket under the alternator?
If they are then obviously I wont be able to remove the bracket so will be the throttle bodies that need to be removed.

Think you can get away with removing just the drivers side body.

When I've done mine,

1) I've released the alternator from the bracket
2) Released the bracket from the engine
3) Wiggled the bracket from underneath the alternator and out the front of the engine
4) Alternator twisted, wiggled & slowly out it come the front of the engine.

Its tight but possible

Thats what I was hoping I could do Ian. I don't want to disturb the throttle bodies if I can help it.
I'll have a go at getting to the other bracket bolts. smile

No not a chance! I can't even move the alternator enough to get to the second pair of bolts holding the bracket in place. I am guessing I got a different Alternator casing to you Ian.

Whats involved in taking the throttle body off? Is it just the 6 allen bolts and the linkage? Are are there 'O' rings between the bodies and block? If there are I might as well replace all eight while i am here.

Well I worked out why the Alternator wouldn't come out with the throttle bodies in place.
It was the heat barriers they had been put in the wrong way round. No effect on the breathing but they are shaped to allow more room for the alternator.
