First post from newb. Got a sweet '97 that's about to make me deaf. Worst of all I can't hear any turbo or exhaust over the fan roar. I just put a new fan clutch (NAPA) on, cleaned radiator and condensor and inspected fan blades. It roars just as bad hot or cold. These old 7.3's are loud enough without that noise. Does anyone have any ideas. I'm considering an electric fan setup if I can find one stout enough.
