I have a Multipla 1.6 petrol yr 2000 which lives in France. Friend was going to take to airport for me to collect next weekend when i fly over but he noticed fan wasn't working and engine was getting hot so didn't use the car. Is this the thermostat? Or a switch or fuse. Any advice would be gratefully received as I don't want to take the car to the garage in France, as I'd end up with a bill greater than the car's worth!
