After having lost both serpentine and A/C belts when an idler pulley disintegrated, I'm gonna be spending my Saturday replacing the water pump, pulleys, tensioners, fan, etc. on my '03 E53. I'd like to make sure I get everything back correctly, but have been unable to find tightening torques (and sequences) for the pulley bolts. Is there an online resource I've missed?? Any help would be very much appreciated!
