Does know of a "How To" so that i can remove the fan shroud as i want to change the water pump, tensioner pulleys.

The only thing stopping me is this dam shroud. Does it split in half or am i missing something apart from skin of my knuckles.

Any help would be appreciated.

Would you have to remove the viscous fan and the cowl together onto no6 Range Rover

Everyone needs a hobby

If V8 m62 petrol, Get a copy of Rave manual it is all in there.
I take off my sump guard / cover, the fan and then the shroud. Lift up and remove the two scrivets at the top, unclip the pipes from the side and it just lifts straight up as it pops out of the location at the bottom.
The hardest part is having the fan holding tool and spanner.
