Default New water pump

I’ve got a new AC Delco water pump to install. I planned on using the old thermostat. After pulling the thermostat housing off the old pump I found the new pump sis t have the same Oring groove. So I ordered up a new thermostat. Does this thing need an additional gasket or should the seal, seal everything up?

I want to replace water pump on my 97 C5. Can you tell me where you got the water pump? Is it OEM water pump? or aftermarket?
Amazon has a AC DELCO Professional brand water pump for $100 and this is aftermarket i believe. Amazon do not have OEM.

Check rock auto they have oem. Thats where i got mine. 225 shipped.

AC Delco makes two water pumps for the C5. One is listed as GM Original Equipment (251-744) and the other listed as Professional (252-846). Amazon sells them for $100 and $200 respectively.
