V6 viscous fan question

[440Interceptor]

Evening all, I want to give the water pump pulley a cleanup and change the pump itself, but how in Hades do you get the fan and pulley off? I know the answer is staring me in the face but....

Pic posted below, any help much appreciated!

Won't those bolt heads undo? You'll need a spanner of course....

The M6 bolts on the fan hold the fan to the viscous hub.

The M8 bolts on the pulley hold the pulley onto the waterpump flange.

You need a large spanner on the square flats just behind the viscous hub that will hold the pump shaft then undo the viscous hub and fan as an assembly, the viscous hub (of that style) screws directly onto the waterpump shaft.

I use a hammer and a blunt chisel/drift on one flat of the big nut on the water pump spindle to break the seal of the thread and just twiddle the whole assembly off

Chris, the shaft behind the 32mm nut is round, no flats on it. I can get a spanner on that nut but the fan assembly just rotates so what else am I turning?

Try holding the water pump drive housing with a oil filter strap, and use a large spanner on the nut of the fan.

They make a wrench (spanner) for this purpose.
I would thjink your local repair guy has one, get him to take it off for you, you can drive home with no fan if you have no traffic lights and the rad cowling in in place.
