Thread: Viscous fan removal?

Fan nut unscrews in the same same direction fan rotates. All you need is long 36mm spanner (36mm serpentine RV8's/TD5’s and 32mm V belt RV8's/TDi’s) and give it hard belt with a heavy hammer.

You will only need to make up a lug tool to hold fan pully if nut is frozen solid. If your spanner is too short Viscous Fan spanners are usefull as they are thin and long and have crank/offset and cost about $30. Ford Viscous Fan Spanners are readilly available in 32mm and 36mm but 36mm a bit hard to find. Solution is put a 32m on the grinder.

I've done it recently, I just used a long screwdriver across two of the fan bolts and a long handle on an adjustable spanner and pulled like hell. put something in between the radiator core and the fan blades to prevent damage like a sheet of metal...I used a sheet of perspex I had lying around.

Just to clairy if its a TD5, the thread is a Normal thread. Not lh.

As has been suggested grind out a 32mm falcon fan spanner (thats what I did) and hit it with a heavy rubber hammer.

This is the method I use too.
I remove one of the 10mm head bolts from the pully to give the EFS(shifter) more room.

success. Thanks for letting me know the job was (super-) humanly possible. I'd tried removing a bolt, using a screw driver to block the shrowd (sprung steel blade just bent wildly) and giving the spanner a sharp short hit, all together and without success before starting this post.

Then went and bought a viscous fan spanner (32mm) and ground it to fit tightly as suggested, see photo. Then sawed a 10mm ring spanner in half, placed it over one of the bolt heads and jammed it's end up against the crank pulley, see other photo. The viscous spanner jaws just sprang apart when I heaved on a spanner handle extension for the extra leaverage I needed, and sprang around the nut a couple of times without effect. Finally with a very big shifter hammered onto the nut and 1 metre of 2" water pipe on it's handle the nut came loose at last.

What satisfaction to see it move but what a horror.
