Anyone have brands/parts numbers for water pumps for use with a 330 with factory air conditioning? Difficult to pin down whether the pumps I've been seeing supports it or not. I've been searching on eBay, and eBay has one option for the Cutlass Supreme in my year (1967). Did all Cutlass Supreme packages come with factory A/C?

 

1) Ebay is NOT a reliable source of part fitment info.

2) A/C was an option and not standard on any Oldsmobile in 1967

3) Search is your friend.

Great link Joe. That tells me the 70 non A/C on my 260 is 5.09" then changes the next year. Really shows plainly where Olds 4 water pump lengths were used.

 

I have a nice 384786 core for rebuild if needed. It has the cast impeller.

 

I did find that list with search, but the problem is that eBay sellers don't really include the dimensions of their pumps.

 

I still have the old pump, which as far as I know works but is super-rusty from sitting half-full. I could just throw that back on if I really needed to.

 

So, I found a GMB 130-2773 pump on Amazon's Warehouse Deals for $11.50 which supposedly fits my engine. It was marked as "used," but I was hoping it was a new open box pump that was simply marked that way since Amazon does that a lot. It is new, but it's the wrong pump. It's the one that's got the weird channel below the larger (intake?) spout. Could I still use this for my engine? Would I have to block the channel up?

 

Wouldn't it be easier to go to your local Napa or auto parts store of your choice and buy one and lay yours next to it on the counter to make sure they are the same?

 

If it has the proper gasket AND is the proper length and the outlet size matches, yes. Oldsmobile is confusing with the multiple length's and outlet sizes. Match those and you are good to go.
