Where can I find the spring loaded belt tensioner on the 1996 mercedes benz c220?

I am trying to replace the serpentine belt. However I can not find the tensioning device.

If you're looking from the front of the engine then you'll see a large pulley on the upper right side of the engine that will be your power steering pump. Just below that and to the left a little is your tensioner. Just use caution not to get your hand wedged inbetween when you let the pulley back after the belt is off.

It will have a pulley attached to it. Be careful taking the tension off. If you slip it will snap back at you like nobody's business.
