The my manual isn't too clear about this - anyone know? There a bolt just the right of the water pump and to left of the alternator. This looks like the water pump drain bolt to me. About 4 inches back toward the trans , in line with the 3rd oil pain bolt and next to a block freeze plug is another bolt which looks like the block drain.

 

if it aint clogged when you open the nut the water should come out.

 

 

You have drain plugs on both front and back of the block!
