Exchanging Accessory Drive How-To Needed

[roadnsky]

So it's removing the distributor first, then maybe the water pump to get at the bolts for the AD, then reverse order to replace the lot...

You don't have to remove the water pump to get to the AD bolts.
Here's a pic of the cavity with the AD removed and you can see the water pump.
(See pics)

It's probably easier though if I remove the spark-plug wires first before lifting out the Distributor. Any other tidbits of lessons learned would be appreciated. Also, where's the thingy I need to mark the position of so I don't upset the timing when replacing the distributor?

You also do NOT need to remove the spark plug wires. Just remove the distributor CAP.

I suggest that you re-read the post that Neil referred to earlier in this thread.
Here is the link

That post will address your other questions and is exactly the procedure that I have used.

Yes thanks, I read that post earlier and have saved a link to it as I intend to follow those instructions.
