6.5 water pumps

Here is the GM technical information difference between a 1999 and a 2000 water pump.
Anyone here have any clue what the real technical difference is?

The only difference I see is that 19168610 takes a bolt-on fan clutch, whereas 19168609 takes the thread-on fan clutch and comes with a pressed-on belt pulley.

Casey, they are both spin on fans...
I have bought both of them.. one sets on the turd Optimizer I just put in my truck. The other is setting on my desk in my shop. I can't physically work on my truck for a couple more weeks but having looked both of them over and the GEP take off I bought from Peninsular a few years back I can't tell any difference.

By the way, I'm trying to get the question answered through AC Delco's "customer support". Yeah, hilarious, right?
That's right they just refer me to call a service facility (GM dealership). What a waste of time, and yes I've done that, too!

I still plan to cut each one in half to compare the insides but I'm covered up and haven't had the time yet..

I'm just basing that off a google search. Pictures of part # 19168610 all come back as a bolt-on fan clutch.
