I'm refering to the engine cooling fan driven by the water pump -- not the electric cooling fan.
I have worked on and modified Mustangs for the past 9 years and I know that the cooling fan has a clutch that will allow it to disengage at higher RPM range. When the engine is shut off, you can do a quick check of the fan clutch by manually rotate the blades by hand and the clutch should have a slight resistence (i.e. the fan should not remain moving after you spin it hard).
While under my hood of my 325iS the other day, I tried to rotate the fan and it would not bugdge. I'm curious if the M50 fan should operate the same way as my Ford.
