Needs new serpentine belt -1992 chevy chyenne truck

NOT SURE IF U ARE KNOW HOW TO DO THIS BUT,YOU CAN CHALLANGE YOURSELF AND SAVE SOME MONEY.WHEN YOU RAISE YOUR HOOD THERE SHOULD BE A DIAGRAM OR A PICTURE IN BLACK AND WHITE THIS IS SHOWING YOU YOUR BELT PATTERN. IN THE EVENT IT'S NOT THERE GO TO AUTOZONE AND ASK FOR A DIAGRAM TO CHANGE YOUR SERPENTINE BELT ,ASK THEM WHICH OF THE PULLIES IS THE TENSIONAL.THE TENSIONAL PULLY MOVES WHEN FORCE IS APPLIED TO IT .SIMPLY GET YOU A LONG ENOUGH CROW BAR IN BETWEEN AND PUSH ,YOU WILL SEE SLACK COME OFF THE BELT.WHEN ENOUGH TENSION IS OFF THE PULLIES SLIDE THE BELT OFF.FOLLOW THE PATTERN FROM YOUR DIAGRAM AND PUT THE NEW ONE ON.

IF YOU CAN I WOULD TAKE THE OLD ONE OFF FIRST TO MAKE SURE THE NEW ONE IS THE SAME SIZE,PROVIDED YOU ARE DOING THE WORK YOUESELF.
