Engine Overhaul This Easter, Advice Needed.

Engine Overhaul This Easter, Advice Needed.
Hi Everyone,
Has anyone got any advice for holding the crank still whilst undoing/doing up the main crank pulley bolt.
Also, does anyone know the correct Torque setting for this bolt.
I'm doing the following work over the Easter weekend, so any advice would be greatly welcomed.
Timing Chains and Tensioners
Water Pump
Thermostat Housing
Front Upper wishbone bushes
Front Discs and Pads
Fan Belt
Oil and Coolant flush and change
Anything i should be looking out for? Anything else you'd recommend doing at the same time.
Thanks everyone.

In the absence of a diagram or photo, I'll take a wild guess that by 'this bolt' you mean the crankshaft damper securing bolt? If so, it's torqued to 364 - 386 Nm.
That's a lot of work even for a Bank Holiday weekend. Most of it is straightforward dismantling / reassembly but the upper wishbone bushes could take ten minutes, several hours or even days to remove.

oops sorry, i renamed the title, after writing the question.
Well its four full days, with three of us tackling it. I'll leave the front suspension work until last, and it'll be done if there is time.
I haven't got a wrench that torques up that high, if i did it 'as tight as humanly possible', say with a 3' bar, would it be safe for a few miles?
I was thinking of taking it to a garage to have them just torque up the bolt to the correct setting. Off the top of my head i can recall if this bolt is accessible once the engine is all back together

so your torque wrench will work

Two helpers = greater speed but bigger beer bill. Worth it!
There's a good chance you'll find the pulley bolt is done up 'tighter than humanly possible' when you try to undo it. The only way I know to lock the crank whilst undoing the pulley bolt is to wedge a lever between one of the torque converter bosses and the housing through the access slot. This is risky so it's worth seeking advice from the techs on the forum before trying it.

After mentioning locking the torque converter which I've done in the past, I thought I'd check what Jaguar recommend:

Surprisingly this is exactly the procedure shown highlighted on the third page!

The water pump i've bought is part number AJ8008912.
It has a plastic impeller, and I'm sure i've seen it mentioned that metal ones are available.
Is this plastic one stronger than the original plastic one, or am i just replacing what i already have?
Thanks for all the responses. It makes life so much easier.

Also, my Alloy thermostat housing hasn't got a lid, the supplier is sending it on. Worst case, will i be able to use the plastic lid for the time being?
The new style primary chain tensioners are metal, inside grey plastic outers. Is this the correct part, ie is this the new style?
Thanks everyone.

If your supplier still has the fifteen year old pumps with the problem impellars, his wife and children must be starving.
There's some thermostat housings with faulty castings on the market in the UK. I had to return one to British Parts UK last year where the lid wouldn't screw down properly. Although you could use the original plastic lid temporarily, it might be safer to wait for the aluminium one to arrive to ensure the housing and lid are a good fit.
(British Parts replaced mine without question and refunded my P&P costs)

Thanks for all the help on this everyone, i really appreciate it.
I don't know if its just me, but, just holding one of these massive brake discs. They're like works of art. I could quite easily look at them all day long.
Really starting to love this car!!
