Make a diagram of how the belt is on the motor,
then cut it off & move on to the next item you have to do

haha, I can reconmand you some motorcycle helmet.http://www.chinasinoy.com/wholesale/video-parking-sensor-with-camera-and-7-tft-monito-2096.html

the mount must be remoived.

iys been while since i messed w/buicks but if the engine is side mounted you must remove motor mount to to put a new one in

1. Remove the engine mount to engine mount bracket nuts. Important: Ensure that the wood block extends past the width of the oil pan in order to avoid damage.
2. Use a jack with a block of wood on the jack under the oil pan in order to support the engine.
3. Remove the engine mount bracket front upper and lower nuts.
4. Remove the engine mount bracket front upper and lower studs and spacer.
5. Lower the engine as necessary and rotate the tensioner to remove the drive belt.Remove the supercharger belt.
6. Reverse For INSTALATION

there is a special tool for this job but I have cheated on this but you ned to be careful when doing this.The wishbone shaped mount on the front going from motor to front of vehicle, remove and it allows the motor to tilt.

that car to my knowlege & replacemt has one engine mount by the belt & 2 tranny mounts one in the front & that canbe purchased at amazon for about $130 alot cheaper then dealer! also rear tranny can be purchase as insert or complete with bracket & mount together! have no clue on tensioner as mine has not went yet!!

This is the diagram but you should have factory belt diagram sticker is still somewhere under the hood

To replace the serpentine belt on a V6 3800 you must jack up the motor and remove a motor mount. You must then use a breaker bar with a socket (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.
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
Good Luck
