Unfortunately GM does not manufacture water pumps anymore and has not for quite a few years. Go to your friendly auto parts store and buy a new one for 1/2 what the GM dealer would charge. You should be able to buy one for less than $40.00

You can buy a brand new one, or some will sell a rebuilt one. If so, it's probably the same casting that was originally used.

The new Delco/GM fan clutches are not made by GM. Delco is nothing but a parts remarketer today.

The current GM part number for a new waterpump for your application is GM #88926099. This pump GM lists for about 95 bucks, but you should be able to buy one for a lot less than that, maybe 60 bucks.

The exact same pump is also available from Delco under their number 252-585. I'd say 40 to 50 bucks from a competitive dealer.

However, the above pumps will not be a GM-branded casting and will not be NCRS correct if judging is in your future. In addition, the pumps will be the same as those available under many other brands. On the other hand, the configuration of the casting will be almost identical to the original except for "numbers".
