84 XJ6 - Removing the Fan
#1
![Default](/forum/images/icons/icon1.gif)
Looks like I'm going to need to remove the fan to be able to turn the crank.
My book says that on later model cars, there should be a bolt and a special washer on the front of the fluid coupling. As a Series III, I'm assuming that would apply to me, but The only thing I can feel on the front of the coupling seems to be a spring.
So, should I be taking the four bolts off to remove the coupling from the pulley?
Thanks!

Long about '82-'83 Jaguar switched from a non-thermal fan clutch with a single bolt in the center to a thermal-type fan clutch with the four studs/nuts arrangment.
So, yes, remove the four nuts holding the fan clutch to the water pump. There's limited room so it's tricky. You'll have to loosen each one a couple turns, jiggle the clutch away from the pump, then loosen them all a couple more turns, repeat, repeat.
It's even more fun on reinstallation :-)
Tip: have some 2 or 3 extra fine-thread nuts on hand. 5/16-24, I think. This way, when you drop a couple (and you will) you'll have extras topside rather than scrounging around on the garage floor.

Well, a few whacks here and there and they popped free. Thanks!
The head is all unbolted and loose, so now I'm just waiting on some burly guys to help me lift it free . . .![Icon Wink](https://www.jaguarforums.com/forum/images/smilies/icon_wink.gif)
And here's something interesting I found in the fan cowl:

I do believe that is a crankshaft nut! I've heard of having spare parts AFTER you put a car back together, but not before it's apart.
This also makes me think this is not the original engine . . .
