excellent guide
I eventually bought the viscous fan holding tool and the VF hub tool for a few quid remembering the pita while undoing the viscous fan during cam belt replacement
thanks again methley

EDIT: replaced the alternator late this afternoon. Defo 1 hour quite easy job even if those two lower bolts are a bit tricky.
I found easier going underneath to undo the lower bolts.
A ratchet spanner is definately essential as all the three bolt threads are long.
for those tool addicted as I am I used this tool to lever the tensioner. This is the square tool I use to undo differential plugs.

Alternator Replaced but I still have the siren noise
Fantastic write up Methley and everyone else who contributed! I did mine this morning and it took me 2 hours, and I am a real novice. The hardest part of me was getting the belt back on after I had fitted the alternator.
I hope you don't mind, but I wanted a copy to print off so I created this document so I could refer to it when I was doing the work:
I hope it helps those beginners like me who need to see the pictures as I could only print off the text from the site!!
I recently bought a re-manufactured turbo and had it fitted by an Indy in Reading for a very reasonable price. However they said there was now a slight whine/siren noise coming from the engine and was it there before - which it wasn't. They said it might be an unbalanced vanes in the Turbo making the noise or it could be the alternator, hence my reason for changing the alternator this morning after reading many of the siren/whine noise posts on this brilliant site.
HOWEVER the noise is still there?!! If it is a noise coming form the Turbo is that something to worry about. I've heard that some of them whine anyway? There is no loss of power and the noise tends to disappear when the engine is warmer. Any other help would be much appreciated!

One of the aux belt idler pulley bearings getting a bit worn perhaps?
I had to replace the tensioner when I did my alternator.Clive

Thanks for the reply crwoody - how would I know if pulley bearings were worn?

Methley - I have recently had a new Air Con Compressor fitted by an Indy - so presumably this should mean the bearing is OK?

The best way I've found is to remove the belt and give the pulleys a spin by hand, also grab them and give a wobble by hand too, to see if there's any noise or undue movement.Clive

As others, many thanks for posting this excellent guide. All done in an hour and a quarter (1/4 hour of which looking for the right tools😜) 13mm ratchet spanner from Aldi really came into its own with the bottom alternator bolts. Thanks again!

Thanks Methley and others. Just changed my alternator in 60 minutes. Glad I bought some flexible ratchet spanners a while back. Only problem I had was the electrics plug - it was hard to get a nice tight fit. In the end a wide set of grips squeezed it in enough for the clip to engage.2005, TDV6 S, Auto, 190k miles, owned from new, V8 Brake Upgrade, Nancom Evo, RLD protector, BAS EGR blanking & Remap, separate ATF cooler, changing all the fluids ahead of time.

I did this job today and used this thread as my guide, and very useful it was too, thank you very much all.
One tip which I have not seen elsewhere is to use a 3/8" socket wrench (or 1/2" with 3/8" adaptor) to loosen the belt tensioner - makes it much easier than the screwdriver method, and safer. It is still tricky to pull the belt on, but I managed it after a couple of attempts.
Thanks again all.
Is there any market for the duff alternators on ebay? I suppose someone must buy them in order to refurbish and re-sell?
Great forum. Thanks.
