My notes cribbed from some forum experts:

Use lots of penetrating oil.

Post 98 models should have the non-sieze manifold nuts fitted.

Drop the front pipe off of the manifold (two bolts accessed from under the car).

Remove the plenum and intake assembly. Alternatively it's just about possible to remove the coolant pipe blind from underneath by reaching around the gearbox.

Remove the scuttle cover.

Drain the coolant.

Disconnect the main stainless steel coolant pipe that runs around the drivers side head at the rear of the block (two bolts, you need to lean over the engine to reach) and remove it.

Make sure you have a new O-ring for this pipe.

Removing the coolant pipe from the block isn't that easy - you need a long E10 socket to get past the oil pipes (and a lot of patience).

Remove the manifold heat shields. There is an extra e10 bolt on the inside of the manifold at the rear – you may find that these will shear off!!!

You also need to remove the heat shield from the exhaust manifold.  The lower heat shield usually comes off with ease (only 2 or 3 E10's)

Unbolt the manifold.

Manifold nuts are locking nuts - when new they are oval at the ends - if you get new ones make sure they give you 13mm nuts - 2.6 & 3.2 went to 10mm nuts not as good.

The Haynes talks about draining the oil and removing the oil filter and oil cooler pipes. This is just to get at the coolant pipe bolts. On mine I could get to the bolts OK.

right i have got to the pont where i am struggling with the E10 bolts at the back of the block and one of the E10 bolts on the heat shield.

The two at the back are impossible to get at with sockets on mine, i have tried everything.

One of the E10 heatshiled bolts is being a pain as the steering box is too close to the manifold and i can't get a socket on it.

Any ideas?

Most Torx bolts can be undone using metric spanner. Makes access that bit easier.

8mm ring spanner or take a trip to Machine Mart, they sell torx ring spanners.

Good to hear you're done, and I'm sure you're gonna sit down with a beer, and imagine that it has been a very satisfying job...

oh yes, was very happy once i had finished it....

Couple of things i have noticed, one if them is that the LH manifold is not starting to blow a bit, that one looks to offer a different type of challenge.
Also the water had a small amount of dark brown sludge in it, shotyl oafter i got the car (easter) i flushed the coolant out and refilled with 50/50 mix, the flushing was done ala Pope method.

Would this the be beginning of the oil cooler starting to give issues, i must say though it was more a rusty brown rather than a mayo coloured

Oil coolers are normally a bit more of a problem that that.  Trouble is, if you drain via tap, and fill up with 50:50 mix, you are only doing around half of coolant.  So your mixture may be more like 25:75

when we did the first drain we undid the tap, as well as bottom hose and top hose, we tried to get as much out as possible, and it did seem that we were swimming in it for a while

tap and bottom rad hose gets about half of it out.  If ever you do a v6 waterpump, you'll see what I mean. There is no easy way to completely drain these motors...

As you've just removed the rear coolant pipe you'll have just drained the entire system.

That coolant pipe is a nightmare isn't it...

Only way to get near completely draining V6 (without completely stripping engine) is to remove water pump....
