six - what milage did you replace the mentioned items at? I have a '95 E320 with 95k miles and have replaced the tensioner pulley and the guide pulley but not the fan pulley. If you have under 120k miles what made you replace them? I have a pulley/belt type of noise between 1500 and 2000 rpm that I am unsure of. I have put the automotive stet. on the air pump and the alternator and it sounds like the air pump is pretty noisy. For right now I am living with it until it gets really bad or something quits.
Once I get on up in rpm/road speed I do not hear/notice it anymore.
