Yikes!
I hadn't thought of timing belt-driven pumps. That would be pretty hardcore to want to mess with one of those. I was thinking more of the belted types. Too GM ingrained, I guess...
If a person changed to a manual steering box, one or two deep-cycle batteries to enable stripping the alternator, and just bite the bullet on air conditioning (balance out the weight of the extra battery?), then the water pump would be the only thing left to go completely beltless!
...or at least not driven off of the engine, that is!
