Simon, you say its dumping the contents of the rad out, but where is it actually comming out of? If there is an air lock in the cooling system, the pressure builds up higher than if the air lock was`nt there, and when you release the filler cap, the water will gush out.

So I am pretty sure you have not got a liner seal problem
The other thing worth a try, once the coolant is in place, is to start the engin with the coolant filler cap off, and as the temperature rises, see if there are any air bubbles comming up into the expansion tank, if there are, this would indicate head gasket failure
Two words of warning, which I am sure you already know,.....do not take the cap off when the engin is hot....and, when you start the engin with the cap removed, immediately check to see if the coolant is being blasted out of the expansion tank all over the altenator, as this indicates an air lock, which stops the coolant from circulating, and is subsequently pumped out of the expansion tank. I would suggest some protection for the altenator

Take John C's advice on filling coolant. Open up radiator valve.
Best to fill slowly from a small container not a hose, I usualy use a 1 litre container. (during filling massage the hoses that go in to thermostat housing lol)
Once full, close rad vent and start engine once temp rises again open rad vent to ensure hot water is coming out and have heating on full blast.
This should eliminate most of the airlocks. (I usually then go for a spin and recheck rad vent after several minutes to reconfirm hot water coming out)
The first two times i filled my coolant, I did so to quickly and ended up with problems another tip is to have the rear right slight higher too.
Since I have adopted the slow method I have not had any airlock /problems,
and I have filled it on countless occasions, dont ask.

Might be worth taking it out and seeing if it opens when you heat a container of water with the thermostat in it, making sure it opens before the water boils. Unfortunately wax stats fail closed, while the bellows type fail open. I dont know which one is fitted to the Alp. I take it you know of the second bleed point by the thremostat.

Then when full start car, and idle to temp slowly adding more if needs be. When a levels been found close the cap and fast idle for a minute or two. Turn the car off, slowly slowly undo the cap so as to allow air out but not coolant then leave it off have a cup of tea and let all the air rise to the top.
Repeat as necessary - sometimes that was once sometimes more....
Hope this helps a little, but had to add my penneth as finally there's something on here i know how to get right!
