ok so I thought that my AC comp was making all sorts of racket under the hood.. so I go and pick up a belt to bypass it.. *****series 13800 AC bypass belt size is around 71-72" in length****** and I stick my head really close and it is the water pump..take the belt back off and wiggle the H20 pump yepper... what i wanna know is what am I in for?? tips..trix....advice.......are the bolts going to break off in the block???? prices?? and should I put a 180 thermostat in it...which area does it go in....kinda frusterated.. for help in advance

so I do have to remove the coolent right? and its not a prob swaping the pullays? cool... its not gonna be to pricy right?
again..
