Crack loose (don't remove) the water pump pulley bolts then use a 10 inch adjustable wrench and rotate the idler pulley arm CCW to relieve the tension on the belt. The tensioner arm has a boss on the casting that can be used to seat the wrench. I have seen some arms with a 3/8" square hole cast into the arm to accomodate a breaker bar drive instead of having a boss with flats. Relieving the tesnion will allow the belt to slip off the grooved pulley.

Remove the belt, remove the pulley nuts. This will allow access to the pump mounting bolts. I think there are 3 or 4 10mmm bolts.
