Chevrolet Repair: Belt replacement question..., bolt head, belt tension

Question
Mr. Sheets,
I've got a 2001 Buick LeSabre (V-6), and I'd like to replace that "serpentine" belt that drives just about everything on that motor.  (Getting a little shiny, and hasn't been replaced in 100,000 miles.)  Is that a real complicated procedure, or could a half-way decent backyard tinkerer do it?  I'm figuring that I'll only have to unscrew a bolt or two to release tension?  I plan to look real close (and draw a diagram) before taking the old one off, so I won't put it back on looped incorrectly.  Is it more complicated than that?  Do I need to have any specialty tools?
Any suggestions, advice you offer is greatly appreciated.
Warm regards,
David Gardner

Answer
GOOD MORNING DAVID, THIS I A VERY EASY JOB. YOU DO NOT NEED TO TAKE THE TENSIONER PULLY BOLT OFF OR LOOSEN IT. NO SPECIAL TOOLS ARE NEEDED. I BELIEVE ON THIS ENGINE THERE IS A 3/8 SLOT TO PUT A RACHET IN THE TESNSIONER SLOT AND PULL BACK OR UP ON THE TENSIONER ITSELF WHICH IN TURN RELEASES THE BELT TENSION. IF YOU PULL ON THE BELT HARD WITH YOUR HAND YOU WILL SEE HOW THE TENSIONER LIFTS UP, THERE IS ALWAYS A METHOD OF MOVING THIS TENSIONER WITHOUT REMOVING IT,, LIKE I SAID ABOVE OR THERE IS A BOLT HEAD TO LIFT ON. [DO NOT REMOVE THE CENTER HOLD DOWN BOLT ...] THE OTHER THING I HAVE RUN INTO IS SOME BUICK ENGINES YOU NEED TO REMOVE THE FRONT ENGINE MOUNT TO REMOVE THIS BELT.. JUST LOOK AT THIS BELT AND SEE IF THE ROUTING GOES AROUND THE MOUNT..IF THIS IS THE CASE JUST REMOVE THE MOUNT AFTER SUPPORTING THE FRONT OF THE ENG WITH A FLOOR JACK AND PIECE OF WOOD TO THE OIL PAN,JUST HOLD IT IN PLACE SO THE ENGINE WILL NOT DROP. DO NOT CRUSH THE PAN BY LIFTING THE MOTOR WHEN IT IS STILL IN THE MOUNT OR ANY FURTHER THEN NEEDED. THIS MAY SOUND WORSE THEN IT IS,BUT IT IS NOT A BIG DEAL. IAM SURE YOU CAN DO THIS...OH AND BY THE WAY IF THERE IS NOT A DRAWING ON HOW THIS BELT IS ROUTED YOU ARE CORRECT IN DRAWING IT OUT. THERE ARE MANY WAYS THIS BELT CAN BE ROUTED,ONLY ONE CRRECT WAY HOWEVER.. I HOPE THIS HELPS YOU AND IF YOU NEED MORE INFO GET BACK TO ME. PLEASE WHEN YOU LEAVE THIS SITE WOULD YOU RATE MY ANSWER.   THANK YOU VERY MUCH,,, TOM
