Let me start a new thread to keep the discussion more focused. (Also might help others find information quicker later. Hopefully)

So, I took the fan shroud out by wiggling it around the fan.

Then I unbolted the four bolts on the back of the fan, hoping the whole construction can be pulled out at that point. Not so fast.

The fan blades are now loose but I cannot pull them out yet. I need to pull this silver pulley first, right? How do I do it?

 

You've got to remove the clutch. So undo the four nuts on the pulley to remove the viscous clutch to remove the fan. It won't come out otherwise...

 

Hi v1rok

This might help, its not hard to get the Fan off you just undo the bolts as in my Photo and then keep easing it Forward till the Fan Clutch comes off.

Put a big sheet underneath it, as its very easy to drop those nuts and never find them again.

 

Thank you both. Yeah, I figured those four back bolts are the ones I need to unbolt...

At first I was concerned because there is very little room back there and the bolts are almost backing into the back of the clutch. But then I when I started I figured I can loosen the bolts little by little and move the clutch back a bit and then loosen some more. So, the fan and the clutch is off.

By the way, the bolts are 1/2" and I think using a longer wrench might be helpful to get a bit more leverage (as the room is very tight)

 

When time comes to reinstall have some extra nuts on hand, topside. This way, when you drop a nut or two....which is almost a given....you won't have to go scrounging around on your hands and knees looking for them !

I am trying to change the fan clutch on my 94. I have removed the 4 nuts from the pulley however there is not enough room to get the fan and clutch out. Do I need to remove the fan shroud or the pulley? If so, which is easier? Is there something I'm missing?

Thanks....Jimmy

 

Not sure about the later cars like yours.

On the earlier V12s I've always had to unfasten the shroud to allow enough wiggle room to get the fan out

The shroud needs to be loosened, or ideally removed. If you don't remove it, it's a good idea to put a piece of cardboard against the radiator to protect it. It's very easy to damage the radiator with a fan blade tip as you're trying to get the fan out.

I've always removed the shroud and fan together once both were unbolted and loose.

 

Thanks...I'll pull the shroud. The shop manual calls for removing the pulley. The shroud looks a lot easier.
Thanks...Jimmy

 

I did what other folks advised me: removed the fan shroud first, then removed the fan.

But note that I had a bit more room to operate because I had previously took the radiator out (needed some fixing)

It is very tight in there...

 

I removed the shroud last night and was able to pull the shroud and fan together. It never ceases to amaze me how the Jag designers went out of their way to make this car so difficult to work on. I love the car and have always enjoyed doing my own maintenance, but this one can be very frustrating at times. I am changes all coolant hoses and flushing system. I gave up on the heater hose between engine and firewall. I'll replace it the next time I pull the engine.

Love this forum, it fills in all the info that's missing from the shop manual.

Thanks...Jim

 

Well, it isn't really making it complicated to work on but to fit a huge package into a tight space.

 

Right. It wasn't engineers saying "How can we make this car hard to work on". It was engineers saying "We need to fit five pounds of ***** into a three pound bag".

Exactly. How can we wedge all that stiff from an XJ12 into a sporty flat coupe!? And as the car's design was more important, function follows form.
