To replace the serpentine belt on the Mercedes C-Class, open the hood and detach the cover at the front of the engine. Using a wrench, pull the tensioner pulley sideways to loosen it. Once the belt is loosened, it can be removed, taking care during the extraction phase.

At this point, you can install the new belt by routing it around the pulleys. After installation, tension the belt using the same wrench used earlier to move the tensioner pulley to the right.
