Most won't even know what a cold chisel is, don't worry. Those who have one will know how to use it.

Next to the long wait, the elbow grease and the tartan paint?

Thanks for the info mcapinha, Much appreciated.
What can I ask is the objection to a fan holding tool/ pulley holding tool. It looks to me to be the tool for the job. Not just for loosening the fan and pulley nuts but also for tightening them up. Range Rover - How To Replace Water Pump P1 - YouTube
A cold chisel I was taught was for cutting through objects and a club hammer looks abit extreme and not a tool I would want anywhere near my beloved Rangey. But hey I'm just a sparky and not a mechanic.
I am abit confused though, the fan seems to spin to the right, the same way you turn the nut to loosen it. If thats the case wouldn't the fan be loosening the nut as it spins instead of tightening it?
Cheers

You forgot to mention the Sky hooks!!
Oh yes sky hooks,the tool is handy for un locking, I just know how to. Carefully improvise,but for doing up iv never botherd as the tension in the belt is just enough to give a tighten up, it's Designed that when the Engine is running It's always Tightening itself up

No that's why you're a leccy. There is no need to tighten the fan. Just screw it on it will tighten itself. Because normally they are as useful as tits on a Mars bar. You won't undo many by hand.

So how much torque do you think is loaded onto the nut as the engine spins the fan against air resistance when it is locked up?

and also the shock load like air gun every time you start it

There is an official torque loading for the viscous fan, but just the action of spinning it onto the thread nips it, the engine and air resistance does the rest i have never tightened one up and i have never known one come off.

You would need to hold the pulley to torque the bolts, but they are not all that tight. You can actually hand hold the pulley to do that. Trick is not to have spanner straight out from pulley but across it as much as possible. That directs most of the turning force to the bolt rather than trying to turn the pulley.

My mistake when I put mine back was to tighten itThere is an official torque loading for the viscous fan, but just the action of spinning it onto the thread nips it, the engine and air resistance does the rest i have never tightened one up and i have never known one come off.

Well, count me in for having the fan come off once..
One of the times I undid mine I sprayed some WD40 (I know it's a Water Dispersant!) on the thread, hoping to make it easier to undo the next time. I then took the Rangie for a spin and when I stopped I heard a noise from the front. After opening the bonnet I saw that the fan had come loose and was resting near the bottom of the rad. I'm guessing that maybe the viscous was locked and the braking power from the pulley (when the engine was turned off) was enough to undo it, since it had been lubricated...

Keep that memory then, it is possibly the only know incidence of that ever happening in history. Unless the engine backfired and turned sharply in the opposite direction that is practically impossible.
