Silver_V

Water pump went out today on my 04 V. Seems that the bearing inside the pump gave out and leaks from the center.Does anyone know a good site or place I can order from, if local I'm in Long Beach, Ca.? Thank you

I hear the C5 Z06 corvette's pump fits too and I'm pretty sure that's what mine has on it. The fan shroud is clearanced to compensate for the the slightly larger pulley. Pretty minimal trimming. That pump goes for around $100. AC Delco 252-846.

yeah...200$ plus for a water pump!? F*$k that noise. My 05's went and I paid 165$ for a new one. Cannot remember where I got it.....but I remember the pump in my C5 being about the same. Call me crazy but 200+ $ for a pump that essentially is the same one that came on many GM vehicles.....whole lotta BS IMO.

Word. Mine went out & I put an LS1 pump on. Only difference is the pulley. It is much narrower on the V but the other still fits fine.

Interesting. I could've sworn when I was looking at pumps recently the Z06 part number was the same as the V, but now as I look again, you guys are correct - different parts.

And to add to my confusion, RockAuto.com shows 4 different ACDelco pumps when I look at the 2004 Corvette. (Their catalog only lists 1 engine, the 5.7L V8, so it doesn't differentiate between Z06 and normal Vettes.) They show the 252-846 that BudRacing mentioned (correlates to GM #19195105, has cast iron impeller, $100); 252-781 (correlates to GM #88926295, also has cast iron impeller, $133); 251-744 (correlates to GM #19256263, says "OE design, stamped steel impeller", $174); and 251-722 (stamped steel impeller, $244). Weird. Based on what I've seen with other pumps (in the SBF world), cast iron impellers are better than stamped steel, so it's interesting that the presumably better pumps are cheaper. gmpartsdirect.com says the 88926296 part has been superceded by 19195105, so that at least partially explains the two different cast iron impeller part numbers.

What do you mean by the pulley being "much narrower on the V"? Do mean the V's pulley is a smaller diameter? Or that the V's pulley is actually more narrow (less area for the belt to ride on)?
