I have a 1995 BMW 740iL, a couple of days ago as I drove on the
interstate, I heard a loud humming sound that only got worst as I
accelerated, I thought it was the transmission, yet the gears engage
correctly. So I stopped at a mechanics and he came to the conclusion
that it was the fan clutch that it was locked.
The question is will a bad fan clutch make a loud humming sound, it
sounds as if the engine were being stressed out, yet it drives fine and
the transmission is engaging correctly.
Can anyone shed some light?
