Full loss of coolant from expansion tank (unclear what caused the loss) - believed to occur over a couple of days.
Car drives normally at all times.
Temperature gauge reads normal. After a short spell of driving with boost (high rev range) the temperature gauge drops quickly - below the scale. Coolant appears to be boiling in the expansion tank.
Have checked for air in system. Doesn't appear to be any air (have checked bleed point and run for a while with expansion tank cap removed). Thanks for advice

going sideways in a fwd
some garages can pressurise the system and test for leaks,
some can analyse the water for noxious gasses, I;e inpending gasket failure.
others just hit and hope, water could vapourise as steam, if boiling up yes,
is cooling fan working,
could be leaky rad leaky heater matrix, pinhole in a water pipe thermostat housing rubber ring letting go, my guess its a zetec that's why I say rubber ring, loose hose clip,, what car would help , water pump gasket or failing pump seal ,
cream under oil cap as per 1-PD would indicate water in oil or dipstick tube or in breather pipes

Does the system run the correct head pressure?
Once its up to temperature does loosening the cap release pressure or not? (It should and must)
Does water flow correctly around the system, has it been checked?
