I have been out shopping this morning in the 110. When I pulled up at home, the temp gauge was more towards the hot side than the centre. I popped the bonnet and the pipe to the radiator (on the right, looking from the front) is warm and supple, but the return back to the engine is substantially cooler (presuming it's actually flowing). The expansion tank is freezing cold, so I'm assuming the thermostat is stuck closed, or busted. Any ideas??
