To replace the serpentine belt on a V6 3800 series non-supercharged motor, you must jack up the motor and remove a motor mount. Before going any further make sure that the factory belt diagram sticker is still somewhere under the hood; if not, make a detailed diagram of the path of the belt. You must then use a breaker bar with a socket (I believe 13/64") and pull it toward the front of the car to release the belt tensioner. Put the new belt on, tighten it, put the mount back on, and lower the jack. Personally I believe that this one is a tough job for the average person with limited tools, and may be better to bring it to a mechanic. **Driving without a belt can cause the motor to overheat, will cut power steering, and will not recharge the battery, so you should probably get a tow**

The Buick Park Avenue nameplate was first used in 1977 on a model of Buick Electra, but did not exist as a standalone model until 1991, when it replaced the Electra.
