I've seen refrence to a hidden bolt on the side of the mount; where is this? I'm sure I'll find it but if someone can point me in the right direction that'll save me some time.
Yeah, sorry I forgot that, you do need to remove heater hoses to get a clear shot. Is it possible for you to snap a quick pic?

As I remember there'* a bolt that holds the metal tubes to the accessory bracket..then they wiggle free and the bolt is accessible.

I got it about two days ago, sorry. I've been troubleshooting a few other things.

The hoses are held in by O-rings, just pull really hard and be careful.
The side bolt is only accessable from under the car; it'* right behind the PS pump and is holding a wire loom in place.

Now I hear a bearing, so I better find that sound and double check everything, I might just need to put the WP pully back on and straighten it out better this time.

That and the damn thing is shaking at over 2K rpm when in gear. I suspect this is a misfire but I managed to replace plugs 1-5 and the wires. Getting number 6 out didn't go to well.

When I replaced my pump, it made some noise for a little while.

Same here. It clicked a bit for the first 100 miles... Of course, I immediately had to drive 100 miles to get home :P

It sounds like a bearing rubbing to me; but then again with the negative terminal disconnected for so long my trip counter went to zero right away so I can tell how long the new pump'* been in.

Thanks for all of your help everybody.
Now that the experence is fresh in my memory (I have the sore knuckels to prove it) I'll add to the guide I used and answer any questions I ended up asking here.

Now to track down that damn shaking...

Two things just came to my mind:

1) Did you pull the idler pulleys? If so, when you put them back on, did you reassemble the guides in the right order? I screwed this part up royally and wound up destroying a pulley and a brand new belt. Check that cause there'* bearings there.

2) Regarding the shaking, when you put the motor mount back on, did that go smoothly? Tightened the the mount and bracket up properly?

Mine sounded like a bearing rubbing also. Just the pump breaking in. Not that yours couldn't be an actual problem.. just sharing my experience.

Dunno what you guys are doing..

When I changed mine it sounded totally normal right from the start.

On the vibration/issue.. tell us more about the battle with plug 6. Could it be cracked or maybe a wire is broken?
