Hi

I've just replaced both coolant temperature sensors, one in the side of the engine and the other in the bottom hose, and the cooling fan, Mine is the one with just the one large fan.

I still have the same fault, which is, the fan comes on randomly. It will come on from cold and stay on a while. Sometimes I can do a few miles without it coming on at all. But mainly its on. Obviously when the fan is on the revs will tick over above 1000rpm. That's how I know the fan is running and when I switch off the engine it usually runs for a few seconds and sounds like a jet engine. I've got air con on this model and am aware that the fan will spin faster with this on but air con is not on when the fault occurs. I'm really stuck as to what it could be.
