How to replace the serpentine belt of the BMW 3 Series E90

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: V-belt

In this video we can see how to replace the serpentine belt of the BMW 3 Series E90 version: this component is located at the front of the car, so the youtuber, who is a professional operator, to show us how to do the operation well, did not hesitate to remove the entire front end, but it is not strictly necessary. With a little less convenience, we can also do it without dismantling everything. Let's start with the central pulley, which is the tensioner, and which must be unscrewed by turning it clockwise, so that it decompresses and releases the belt. To reposition it, we start from the crankshaft pulley, then to the steering pulley, we turn it around the alternator pulley, the air conditioning compressor, and then to the tensioner pulley (make sure it does not need to be changed).
