It would have been 12562459 from the factory; however, GM changed LSX pumps in 2004, so all replacements are 12600172 (ACDelco #251-744). If going with new style, you'll need two bolts (11516480) and new thermostat housing (15-11057).

I'm going to presume that it is likely a "LS2-style" pump, but you'd want to verify for sure. Nonetheless, I'm not sure it's an upgrade -- or downgrade. I'd just get whatever is cheaper, honestly.

bump, i typed 12600172 in gmpartsdirect and it shows the thermostat housing. All other numbers dont give results including in rock auto. Anyone else have an updated part number. I just need to find an oem replacement to avoid an autozone part.

Thanks

So here is the part number for ac delco 252846. and this is the alternative number = 19195105. Just for future reference. Summitracing is out of stock so ill have to call rockauto to see if they have it in stock.

Thanks
