It's function is to keep the tension on your serpentine belt at the correct tightness. On most vehicles you will need to take the tension off in order to change the serpentine belt. On many vehicles this is accomplished by placing a socket and ratchet (usually 1/2 inch will be required) on the bolt on the end of the pulley. By using the ratchet you take the tension off enabling you to remove the belt. To place the new belt on just repeat the process enabling you to slip the new belt in to place on the pulley. For proper belt arrangement most vehicles have a diagram under the hood in the engine compartment.
