Range EFI V8 - 1991 - Viscous fan nut direction

HI everyone ,
Before insisting like crazy and doing something stupid, I would like to have an informed opinion on the direction of loosening the 32 mm fan nut.
I read everything and its opposite: no screws on the left, on the right, unscrew in the direction of rotation of the fan, in the opposite direction...
Well I tried in both directions with a spanner + mass, and by blocking the belts, it doesn't move! with air conditioning
It's a 1991 V8 with A/C and V-belts.

I dont know the classic but looking at the fan which turns clockwise i would say undo that way, big spanner and a sharp clout with a hammer.

Always the direction in which the fan rotates.

Toujours le sens dans lequel le ventilateur tourne.

so it's tightened to torque ...

Undoes clockwise for V belt V8 and anti-clockwise for serpentine belt V8.
Usually needs a good whack on the spanner to shock it loose.
