Model: Mercedes Classe B W245, MK 1 - Years 2005-2011
Part: V-belt

How to replace a serpentine belt on a Mercedes Class B W245 version? We see it in this video: we will need a 15 combination wrench, then we lift the car and place it on stands to ensure its safety. In fact, from below we can see the serpentine belt well; we remove the tensioner pulley, remove the belt. We take the opportunity to check the conditions of the tensioner pulley and the idler pulley, because this is the ideal opportunity to replace them. We put the new serpentine belt back in place, keeping its original position, which we can see in an explanatory drawing inside the video, and make sure it is well tensioned on all pulleys. Now we start the engine for a few minutes, then we can lower the car.
