Usually the starter is attached to the bell of the transmission. It typically is in the shape of a long cyllinder with a small motor attached to it. Before you replace try knocking the larger cylinder with a hammer. Sometimes the internal components are simply stuck. Before you change if it is necessary, don't forget to disconnect the battery negative. There are not really any special tasks. You just unbolt, unplug, remove and replace.
How do I change a starter on a 1997 Monte Carlo?
I 2nd the hammer trick. I had to use this technique to start my 79 blazer from time to time. You will eventually need to replace the starter if it acts up too often.
