Re: Overheating GTV 3.0
head gaskets tend to go if the engine is run too hot for too long, Does it overheat when in traffic or when thrashing it?
Could be the water pump, some of the V6 ones were plastic impellers AFAIK and tend to slip on the spindle thus not circulating water round the system properly.
Or it could be something simple like an airlock in the pipes (or even the wrong thermostat), try squeezing the pipes a few times and check the coolant level.
Failing that, get it back to the garage and tell them it was fine until they had it.
