Water Pump Replacement
Good Day...Gentlemen,
...trying to put together my C5. Was overheating and I decided it was time to replace the water pump, radiator, hoses etc. On the casting the water pump there is what I think a part number of 12600470. When I search on the various automotive parts places I cannot find an exact match. Got any ideas or recommendations on this replacement?

Water Pump
Thanks for the input on the GM Water Pump. Was it assembled in the U.S.? From what I have seen on various sites prices for the pumps vary from a low of $75 ( Gates ) up to over $200 ( AC Delco ) just for the pump only and possibly gaskets. Prices are all over the place...bottom line is fit and finish...

ACDelco 251-744: OEM replacement that uses the newer style water neck with separate thermostat. Made in USA I believe
ACDelco 252-846: "Professional" series that's made overseas, a lot cheaper. Uses older style water neck with built in thermostat. I bought this one and it works well. Only issue I've had is the bracket on it caused my blower setup to be misaligned slightly... was not an issue with the autotensioner when I was NA.

I stay away from Chinese parts. The kit from gm direct is cheap all things considered. If another option is considerably cheaper, it’s probably too good to be true.
