My Vt acclaim series 2 has recently just started boiling over on idle I'm pretty sure.
It dumps a **** load of coolent onto the ground and steam comes up through the reservoir,

Any advice for this ?? Cheers

I'd start with replacing the themostat and the radiator cap.

If the temps aren't rising but it's boiling than it's a good sign the system isn't pressurising correctly. Replace the radiator cap.

Have the system pressure tested to check for a leak, if none is flush and correctly bleed the system to remove air locks.

Yep...as already mentioned, replace radiator cap and change the thermostat. Make sure the system is bled properly (there are in depth 'how to' procedures on the forum) otherwise u will have dramas with temps spiking

Um, how long is it idleing before this happens? How old is the engine? does the gauge show it's hot? Does the cooling fan work? Cuz dumping all the coolant and steam out the overflow bottle is pretty servere.

Did any one say compression test before throwing parts at it?
