The wrench kit from O'Reilly's does nothing to stop the water pump pulley from spinning. Looking at the engine, I'm supposed to rotate the nut to the left correct?

I tried prying the pulley bit when I counter with the wrench, it just starts to spin again.

Rent Part number 67065, its the pulley holder, u need to put 2 bolts of your own through the tool then those bolts go into the holes on your water pump pulley. Then you use the wrench set that u rented. You can do that or buy Lisle prt number 34580 @ 30 bucks to hold down the pulley. You also have the option of buying a set that comes with both the hold down wrench and the loosening wrench @ 80 bucks, thats Lisle part number 43600. Type those part numbers into their website to look at pics. Turn the nut to the left and pulley to the right to loosen.

 

I left the serpentine belt in place, put a big crescent wrench on the nut, and whacked the end of the wrench a couple times to get it to break loose. After that, it threaded off by hand.

 

Are you trying to separate the fan clutch from the pump? I took the whole pump off and took it to a shop. They tried various methods (wrench, breaker bar, air hammer, etc) but gave it back to me and told me to buy new parts - that nut was rusted on to hell. I ended up taking their advice. I don't remember the parts being terribly expensive.
