....on our cts-v's? looking around it seems like all ls motors have the same water pump, the only thing I am worried about is clearance issues with the width of the pulley itself, and hitting the radiator fans...here is a pic of the difference

CTS-V


F-body


anyone know if it will fit?

No clue but you could swap pullies and cut the shaft off. But why not juat buy the right one? Cost?

It won't fit. I bought one for a c5 vette, that matches your picture because the experts at NAPA said it was the same and would fit...

It contacted the fans and the belt did not line up properly. It bolts to the motor fine, but you would never be able to get the belt on. Also, if you ever needed to remove the fans/radiator you would have to remove the pump.

Luke at Lindsey sells them for a good price and ships quickly.

I think he already put it on and said it fits. He had another thread on LS1
