Paul, the thermostat is quite easy to change and despite what both Darren Bowker and Steve Wynne said independently, they haven't been reliable in _my_ experience :-) However if you can make the temperature fall by turning on the fans, then it isn't the thermostat.

It sounds like the water pump isn't circulating as well as it should - ie is good enough at idle but not when revved. At a standstill, revving the engine with the fans on should make the temp come down FASTER as the pump's circulating the coolant a lot faster.

John's is overheating within a couple of miles which sounds more like head gaskets, or completely failed pump - yours could be what Walt suggested... would have to have a look to get a better idea.
