Cast iron impeller, and not clear to me what year it is for?? The listed part# is just the casting number, it's not a '87-95 and doesn't look like it is machined correctly for the earlier tensioner setup?

That casting no crosses to a 180-2150, which is used for a rebuilt GMB pump and shows it fits a number of years. Why no part number on the pump? Makes me nervous.

Looks identical to the pump I just pulled out of my 87. That pump was from 1999.

Somebody scooped it up.

Why do you want to know about the model of pump.

Jerry Feather

Johny, I think it is kind of a moot question since this thread is 5 and a half years old. Or, am I missing something about your post?

Model is important, as the 32V unit (at least) is different in its alignment, apart from the tensioner pivot post. In the pic , early pump on right, note that the pulley is further from the mounting face than that on the later pump. Its not an illusion.

There's an extended discussion, now historical, about the impeller material (plastic is better) and the quality of the bearing cartridge used. Choosing the lowest-cost discount knock-off pump risks the metal impeller working it's way to the rear and re-machining the cavity in the block. Getting the wrong pump can be a pretty expensive choice.
