generally you back up the spring loaded tensioner enough to remove the belt --then just put on a new belt but and there is a big but there are several GM 3.8 engines ---one of which requires the removal of the front motor mount which means the engine has to be supported while you are changing the belt---be aware there is always a diagram of the belt routing under the hood someware
