usually you don't. Use a socket wrench with an extra long handle or "breaker bar". Turn in the direction indicated on the tensioner, and the tensioner will move enough for you to remove the belt. Once the belt is off, you can remove the tensioner if you have to.
Insert a 3/8 breaker bar or wrench into the notch on the tensioner and pull upwards (towards back of the car). Then you can change the belt.
Place a breaker bar on the lug/hole on the tensioner; then pry against the tensioner.
There is a spring loaded belt tensioner with a pulley located below the alternator. You will need a 3/8 drive ratchet or breaker bar(breaker bar gives you more leverage). Insert the breaker bar into the square hole on tensioner and push down or counterclockwise and remove belt. If tensioner does not spring back spray it with lubricant and work it back and forth-they stick sometimes.
The tensioner/tensioner pulley is located on the passenger side of the motor and hold the tension on the serpentine belt. In order to change the serpentine belt you must relax the tension with a breaker bar or equivalent. We have more info, including diagrams at our enthusiast forum, at www.trailvoy.com

Pry bar.
I have worked with my 1994 and 1995 models of 900 - presuming the same for newer models. The tensioner is located on theupper end near the firewall. I found it most easily managed by using a 1/2 inch breaker bar.
there should be a hole on the tensioner bar that fits a 3/8 ratchet. using the ratchet rotate the bar counter-clockwise(on a 2000 mustang) to loosen the belt.
The average cost of a 2000 Oldsmobile And tree sway bar is $68. The sway bar can be found for as low as $45 at some discount auto-parts stores.
