During the last week or so I've been noticing a squealing
noise occasionally coming from under the hood of my '91
300D 2.5. It sounds like a loose belt, and arises (1) when
I'm braking, and (2) when I'm coasting downhill without the
brakes being applied. There's no apparent relationship to
steering inputs, so I've ruled out a loose belt on the power
The noise seldom, if ever, arises when the engine is under
load. And when it happens while the car is idling in drive,
applying the brakes will usually cause it to stop. All of
this sounds contradictory, which is why I'm puzzled.
Any ideas what the cause might be?
