sure posted a number of times, but:

viscous off
top end of bottom hose off
3 bolts hold housing on, remove
stat sits in housing

Most factors sell.

(TIS says coolant transfer rail has to come off, but I never have

Nor me. A bit more of a fiddle, but nothing major.  :y

no need to remove viscous fan in my case anyway, as i run without one, but now temperature is up and down like a pair of pants so suspect a sticky thermostat.

Best to use the genuine Vx red stuff at 50% strength.
Capacity is 10 litres, so pour in the whole 5 litre container's worth.
You'll need to drain the system completely. There's a tapered bolt on the offside of the cylinder block, just aft of the turbo.

As you'll need to purchase a 5 litre container from Vx, it'll be best to do a complete (block and rad) drain anyway.
If you can't find the block drain-bolt, 'PM' me your email address, and I'll forward a drawing.

If you're pulling out the stat, you will lose virtually all of it, so no harm in doing a complete job - consider the previous coolant change a bit of a flush ;)

Antifreeze is dirt cheap anyway...
