It's been many years since I had to mess with a water pump, and never on a corvette. Yesterday I was cruisin' and suddenly began to smell antifreeze. I had my passenger check around the footwell to see if there was any wetness and began watching the temp guage - it wasn't moving - yet! But then suddenly it began to swing to the right so I pulled over.

Sounds more like the gasket failed on that side.  Replace them both.  In my experience though, if you've got the pump off  to replace the gasket it wouldn't hurt to replace it if it's pretty old. Usually, when they go bad, they leak out the bearing seal. And they'll always fail when you least want it to.

 When I first bought mine, in fact on my first long drive, the gasket on one side failed . I replaced both and 2 days later the pump failed. So I had to replace them again. Sucked.  Not sure if it's coincedence but...

Look at the small hole at the bottom of the bearing area behind the pulley.  If there is any sign of seepage/water running, replace the pump even if the gaskets have failed.

Sounds like a hose...have you filled it back with water and started it to see if it leaked when cold?
Most of the time, the weep hole in the bottom of the pump will leak worse while running than not running, depending on the pressure in the system at the time.
the fact that you smelled anti freeze leans to a leak to the side, where it would splash on the exhaust. I've never seen a wp gasket just give up the ghost like that if it hasn't been worked on lately, but I guess anything is possible on our cars!

 Joel-

 To clarify, when mine blew out, it literally blew out. The car hadn't been run in a year or so and when I ran the heck out of it... 

  Lesson ...old dried out stuff leaks.

Hey!
Are you implying that I leak?!?!?

When my pump went, I heard a squealing like a belt being too loose, (could have been fluid on the belts), then a clattering like bbbaaaaddddd valve train noise, then the famous smell of Riunite Wine, er, ah, Antifreeze (for those not old enough, they found antifrees in Riunite wine in the '70's).

You know, that's interesting because the last few times I started it up I heard an awful whining noise under the hood, but I assumed it was a dry belt. After it ran for about a minute or maybe two, it would stop altogether.
