Jason67,

I have two 9782482 water pump cores. One has a date code H157. The other has no date code. It does have the casting number and "GM". Both have the original cast iron impellers.
I'm not sure when GM started adding date codes to water pumps. I thought the early pumps did not have date codes.
I can send photos if interested. Price $30.00 plus shipping.
Send me an email [email protected].

X2. Have yet to see a waterpump with an early 67 date.

Default 67 dates

I had a B147 dated coded pump, but it was so corroded and frozen, I broke the casting trying to press out the bearings/seals. They are out there for the date range I'm looking for. Now Pre-January 67, probably no dates on castings.
Thanks.
