vissy fan

right, i think ive stuffed my vissy fan( wont know till morning for sure when its cooled off!

i changed the water pump, and in order to get the fan off i had to heat the nut.

the fan is now stiff and was stiff when i put it on (it was cold at this point)

is it likely to cause any issues? i know it might use more fuel and it is a bit noisy-er but will it fail and just go loose and stop rotating or will it stay stiff?

when i say stiff, i mean it will turn but there is a grinding sound but the fan will move without turning the pulley! this was with angine hot/normal temp!

if its stiff and still goes round shouldnt really be a problem as old cars use to have a fixed fan that went round all the time and it never done them any harm
