Coolant problem with Vauxhall Vectra

I have a problem with my 2005 Vauxhall Vectra C 1.9 diesel, which dumps the coolant out of the overflow tank every time I drive it. Also the temp gauge never leaves zero.

I have changed the filler cap and it has not helped. The only place I can see the coolant leaking is on the tank. Could it be that the thermostat has failed in the closed position?

You've got an airlock. Could be a problem with the thermostat. But if just an airlock you can probably purge it yourself by running to temperature with the expansion tank pressure cap off.
