Water Pump Question
I'm pretty sure mine has started to weep a little. I'm getting a very slight belt squeak on cold starts. It looks like an easy enough job. 
I have an '02, but I hear people recommending the 04+ pumps because they don't use the (expensive) integrated water neck + t-stat? So if I go this route, I'm assuming I'll also need to pick up a new water neck and t-stat? Is that correct?
TIA

The LS3 pump still appears to be the way to go though.

Correct. Separate housing/stat, etc. but it's LS3 pump that seems to be the way to go from all I'm hearing. Better impeller design, lighter, etc. and direct bolt-up.

Yep, I found a few more old posts suggesting the 05+ LS2 pumps. Is that the same part number as the 08 LS3 pump? It does look to be a better design. I like the smaller bell.

The new style LS3 pump has recently become the standardized GM replacement for all LSx Corvette engines. It comes with a 187 degree thermostat and housing.

I wouldn't go that far, perhaps for Corvettes. The F-body, GTO and CTS-V require that larger bell for their different belt configurations.
