I seem to be having trouble with my car overheating. I've had a new thermostat fitted, some new cap and new pipe thing. My mechanic (I use that word lightly) says it could be the heater matrix or maybe the radiator - even I think there's a big difference there!! It's been a great motor up until now - I got it back in 2009 and never had a problem. Also, the mechanic can't find the headlight fuse. I don't have the little box in the car which is shown on the google pics - again he seems to think it is probably within some "mainframe" part in the engine. Any idea please anybody?
