Where are you supposed to mount the accessory brackets to on the Stewart water pumps. I ordered a Stage 2 part #23123 and it looks like this. Anyone else have this problem?

The red dots are where the bolt holes should be.

You have the wrong pump.

I have a Stewart Stage 2 pump on my 83 L69 Z28; it has all those holes, right where they're supposed to be. Look at a 21113 on their web site, that's the one I have. It looks like you need that one except in a LH rotation model.

I agree with that...you have a reverse rotation model which doesn't need the extra accessory mounting holes.

I thought the thirdgen's used the reverse rotation pumps? Or was it just the serpentine setups? Oh well. I'm goingt to call them when they open.

 

V-belt thirdgens have a clockwise rotation, as every belt pretty much just goes in a circle (okay, a lumpy circle). Sine the crank goes clockwise, everything else is going clockwise too.

Serpentines however go counterclockwise because the belt is routed in all sorts of funky ways, and it ends up turning the water pump the opposite way.

 

If you gte in abind and they won't take it back, drop me an email, i might be interested.

I spoken with Stewart already and shipped it back. The correct pump is the 23113 which they list as for cars up to '86. It is a CW
pump w/ accessory bolt holes. Thanks again guys. I am getting so frustrated with all the problems with parts for this engine it's not funny any more.
