Mind that my car is a 1981 505s Turbo Diesel
But yeah, the belt driven fan is connected to the same relay as the aux fan.
I almost took the fan clutch apart until I realised it has an electric
clutch. I found the wire going to the fan and put 12VDC to it while the
engine was off, bingo the clutch kicked in and the fan was solid (not
turning) with the belt.
I hope this helps.
I have received so much help from this group it feels really great to give
something back.
