Holes in a water pump are called "weep holes". If the water pump shaft seal goes bad, it lets the leaking antifreeze drain to give you an indication that it is time to replace the water pump.

To remove the fan clutch, there are 4 bolts that hold the fan to the water pump pulley. Remove 2 of these bolts and replace them with 2 and a half inch bolts. Then you can hold the 2 longer bolts by putting a pry bar between them and spin the clutch off with a wrench. You will probably bend the longer bolts, but who cares? I can't remember if the fan clutch is reverse threaded, so try force both ways before you go crazy in one direction.
