84 iron duke waterpump HOUSING????? (Page 1/1)
Kaosis143 SEP 19, 01:43 PM
So i have a stock 84 fiero and unfortunately the waterpump housing has cracked and warped........ let me repeat that not the waterpump, the housing between the waterpump and block is junk. I have spent a good bit of time looking and it would appear that the housing is an obsolete part that you can only get from a junkyard. My question question is the waterpump the same on any other gm models using the old iron duke since im having trouble finding a parts fiero in my area with a 4 cylinder. Any help would be greatly appreciated as I need my hotrod back on the road shortly. Thanks in advance.

You'd probably have no trouble getting one in The Mall.

P22 Parts Book I have doesn't show a separate part number for part you are looking for.
But water pumps are available as separate, or together with housing.

84-88 Duke shows as water pump/housing as one unit in listing.
Part Number listed as 10042949

Too bad the eBay seller doesn't have picture of back half of pump showing housing better.

In diagram section of P22 Parts Book, the water pump/housing is listed as PN 10159526

Then this Part Number on eBay also lists as for the Fiero (but I can't confirm part number)
