Ive just done some work on my THOR 4.6 and if the same it should just be a case of putting a spanner on one of the bolts holding the pully to the water pump then put the fan spanner on and give it a good hit to the left. Should be enough to hold it unless someone has bodged it putting it on and actually tightened it!! then your pretty much stuffed and will need to unbolt it at the water pump and do it in a vice.
Ive been there before with a friends GEMS so know it can be done!!

You have been told how to do it many times, decent 32 spanner and an hammer. It needs to be shocked loose. Trying to turn it with an Ebay spanner made from soft cheese does not work all that often.

Giving it a good hit to the left on his car will only tighten it up i am afraid. Fans ALWAYS undo in the direction they rotate.

long socket extension or 2 - then hit the flat of the nut on the right hand side - takes a few blows but always undoes ( removed 2 p38 TD fans this week using this method after spanner and hammer did not work)
RR. 2.5 d, has in the past had the Viscus fan shocked off with a hammer and chisel, looking at the tell tale marks it was put back on the same way. I have a very good spanner that has been used many times to remove these fans. I have remove the bolts from the water pump shaft and fitted a pair of 10 inch mole grips, with an extension bar, then using the spanner and another extension bar tried to undo the thing still no luck, so I suppose it's pump out? Unless you know different?

That's a good one, idiot born every minute. Sometimes i wish it was illegal for amateurs to work on cars.

I made a 'spanner' out of a plate of 6mm steel ..
A good swing with a 2lb lump hammer shocked mine straight off .. though mine was a Disco 300Tdi, the principle is the same ..
PS, ignore the safety boots, you don't have to be as careful ...

They won't, I misled you it isn't a separate captive nut, It's actually part of the viscous coupling casting, or at least it's a part of the 'bearing' race or centre of the VC. Sorry.

if you hit the center of each flat in turn with flat ended punch enough times nut will unscrew by hand
