Old thread yes, but how I remove the water pump bolts is I get two 10mm wrenches and clamp them in vise grips. I use the handle part of the wrench and place it through 2 bolts to keep the pulley from moving while I loosen the third. Once I break a bolt loose, I spin the pulley around to the next position, and repeat. Once I have them all broke loose, I just kind of get in there with my fingers and finish by hand. The hardest part is lining up the bolt holes during assembly. It'll make you cuss!
