Can anyone help me with the route of the serpentine belt on a 126. Would love a diagram if any one has one. Car has AC. Have just changed the bearing houseing for the fan. It litterely fell out with all the ball bearings when i stripped it apart. Acording to my local dealers it is only the second one they have heard of. Would of gone right through my rad if it had let go. I thought it was the water pump when i heard it. Might be a good idea to pull up hard on the fan of your 103 engine to be on the safe side
