Is your engine set up anything like the older 1.6 NA diesels?

I faced a similar problem with my 81 Rabbit Diesel.  My water pump
(accessory belt driven like you are talking about) was leaking but I didn't
want to mess with the timing belt (on that same notion, I didn't want to
remove the injection pump as the Bentley suggested) so I removed the
alternator-A/C compressor and their brackets but to get to the water pump
bolts I had to get a "S-shaped wrench" to get behind the injection pump to
the bolts.  I'm guessing it would have taken just as much time to remove
the injection pump and re-do the timing so I was happy with what I did.

BTW - here is a picture of the shape of wrench I had to buy.  13mm on mine.

Hope this helps.  From what I understand, it is a time consuming job
regardless of which way you do it.
