Thank you for your reply Fiona. The garage's response is not a surprise but almost certainly the wrong diagnosis. It's extremely unlikely to be a head gasket problem on a V6 (this afflicts only the 1.8 engine but garages do not distinguish between the two). Talk of a replacement engine is frankly ridiculous.

The garage seems to be saying that the coolant is being ejected through the expansion tank cap, there being no mention of a leak in the 'V'. This could simply be the result of a faulty radiator fan as I mentioned last time. I would urge you to get the test I described done as soon as possible to either confirm this or rule it out.

The necessity to bleed the system only occurs after it has been drained for repair work, so if none has been done then an air lock is unlikely.

Jon also asks this:

If the overheating is very rapid, irreversible and occurs irrespective of road speed then yes, that is a possibility, although a rare one. Check the radiator fan operation first.

I agree with your plans to do whatever you can yourselves and to not use that garage again. I look forward to the next bulletin!
