Hi All, I actually have two 2001 Taurus's: one an LX & the other an SE, both with over 180,000 miles. I Believe the SE has a bad fuel pump (cranks and won't catch unless we spray some starter fluid up the intake). Anyway, recently our LX (3.0L, V6 OHV) started making a loud noise from the engine compartment. The Taurus SE had also just started to make a similar sound not to long before the fuel pump died. Anyway I posted the video's on you tube under: 2001 Taurus LX Engine sounds loud (V6 3.0 auto with a/cand another video with the serpentine belt off:. The consensus of those who viewed the 2 viedos (and there is also another video posted showing the SE engine noise) is that there is a bad pulley bearing. I have changed out the idler pulley & tensioner pulley but the sound is there. When the serpentine belt is removed the loud noise seems to go away so it would appear that the bad pulley/bearing is probably correct. The water pump pulley turns fine in both directions. I cannot turn the a/c pulley much at all(by hand) and I am inclined to think that is the trouble. The air conditioner pumps out cold air so I think the a/c compressor is fine. I have been told that it is possible to change out the a/c clutch pulley assembly without having to discharge the a/c system & I am ready to do so. I am also aware that there are two methods to doing so. One method is to access the a/c compressor from the top, and the other method is to jack up the car and un-bolt the sub-frame. Can anyone here tell me what would be the easiest? I am not a mechanic by trade but I have had to work on cars a lot. However, when I hear "dropping the sub-frame" it sounds a little intimidating. Once I know what to do on the LX I can work on the SE. So, if anyone has the steps to either method I would appreciate if you could post them. Also, if you happen to have pictures that would be even better. All the input is greatly appreciated and I thank you in advance for advice and assistance. By the way, my shade-tree mechanic cousin mentioned something about burnishing the fan/clutch?? Anyone heard of this before?
