I have exhausted all possible search for this pump, but no results. I need your HELP in locating one. I know you are not a parts staff but hope you may give me some idea where to find this pump.
AC Delco number 251-721. GM part number 25808860.

Thanks for all you can do to assist.

Sure, the auxiliary water pump is located on the left front of the engine compartment. Check out the images (Below). Please let us know if you need anything else to get the problem fixed.

I'm trying to find a physical pump. Not the location in the engine. Sorry for the misunderstanding.

Thanks, Ken. You are absolutely right. Yes, it's on back order at the dealership and don't know when it will be available. I've called various auto parts stores as well as other GM dealerships. Out of stock, on back order, not available, etc.
My wife is driving this car locally only, no long trips. We are blessed to have a second car to drive.

Thanks again,

Bob
