Well, removing an engine mount may make it a slightly non-trivial job....
Interestingly, I have replaced my serpentine belt 3 times because in 2 cases it was squeling so loud that I couldn't tolerate it, but I could never see anything physically wrong with the belt. I keep one of old belts in my car, just in case. I usually drive a RWD vehicle, so a belt change in my case is a piece of cake.
