Default 84 XJ6 - Removing the Fan

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.

Cheers

The crank can be turned from underneath. Slide a 1 5/16" socket wrench between the trans cooler and stabilizer bar. You might need to remove the fasteners that hold the trans cooler to the radiator support to move it slightly.

Thanks guy! I got it off and the sprockets are disconnected.

Now I'm trying to figure out how to get the cam bearing caps to come off so I can take the camshafts out!

I usually loosen all the caps a few threads and tap the sides of the cam caps until they let the cam 'snap' loose. Keep even pressure on the length of the cam so it has less chance of bending/breaking. They are brittle and won't flex much.

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 . . .

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 . . .
