not the springs in most cases just the bushings they ride in, also check for lack of lubrication of the leafs, they have nylon slide strips between the leafs, but they fall out and then the spring loads up on braking and then unwind and you fell a thunk when it does so, there is a special grease injection tool/tip for a grease gun that is used to get grease into the leaf segments that really helps, use a Teflon based grease to to this, it is blue in color and available at many up scale parts stores like NAPA and Carquest.

It sounds like you have a broken serpentine belt tensioner. The tensioner should always be tight, it is spring loaded and you would have had to release the tension on it to have put the new belt on.Depending on what engine that is in yours, this could be an easy fix or a hard fix. The tensioner on a 2.2L is made into a large plate bracket that is attached to the front on the engine and several other items have to come off to replace it.The tensioner on the 3.1L v6 is smaller and has one bolt that holds it on.Either one is available at the local auto parts store.
Hope this helps

You can run down to your local auto parts store and buy a serp belt tool. Or you can take a 3/8 drive ratchet, locate the 3/8 square hole in your tensioner and put the ratchet in the hole. For more leverage I put a deep socket over the ratchet handle and put a long 3/8 extention in the deep socket. This will provide ample leverage and will save buying more tools you do not need. Simply move the tensioner to the direction that takes pressure off of the belt.
