Okay on further investigation there seems to be another problem. The temperature gauge is showing over halfway even tho the engine has been sitting for about 4 hours? Could this be the thermostat and could a faulty thermostat cause my expansion tank to run dry? Also done a dial check before anyone mention it. I filled it up with water 4 hours ago and it's still full so must be a slow leak if it's leaking at all.
I would check thermostat and water pump I would suspect them 2 or a leak in the radiator?

check your bottom lower hose from the rad, follow it to the block.
if its coming off, you see a thread looking pipe thats ment to have the hose on. ( usually held via a jub clip or another type of clip )
mine drained its self and got really hot with no water ( smoke and steam to )
thats hose im on about, it was coming off on mine, so when the engine was running, the pressure forced water out of the hose due to not being secure on the threaded pipe.
hope this makes sence

easily if it's a non original with a plastic impelar. Just say no to cheap water pumps

Had yet another look at my car today, I'm now having to fill the expansion bottle every morning.
Things I have checked,
Water pump no leaks but still may not be working
thermostat no leaks
head gasket no leaks or problems that I can see
oil and oil cap all fine
expansion bottle is fine
checked the hoses most of them seem fine apart from one on the bottom passenger side of the rad
Okay, some things that are bothering me, first the circulation of the coolant going back into the expansion bottle, coolant is not flowing back into the bottle, another thing after 15 mins of driving the rad was barely warm is that normal??? Even tho the temp was sitting at halfway how it should. Then A/C rad has come apart from the main rad! Video link below.

I don't think it's the head gasket - surely you would notice 2 litres of water mixing with the oil per day!
There must be a leak somewhere. It kinda reminds me of my old mk3 golf vr6. I always had to carry 4L of water around with me on a daily basis.

Unless you were giving it death 15 minutes is not long enough to get the rad to a hot to touch temperature anyway. Is it not possible it could be an airlock? If you can't physically see where the coolant is going it must be going somewhere, if it was the head gasket you'd know about it on these, it would be hammering it out the back.
Check if theres any on the sump guard if you've still got it on?

I think what has happened is where the a/c rad has been swinging back and forth into the main rad, what's happend is the a/c rad must of puntcherd a hole in the radiator. I can't find any leaking hoses and have checked everything I can think of. Water pump head gasket heater matrix thermostat. I have it booked in with ren tech in Portsmouth. I will Report back for future reference.
