Ah, the good ol Chav EtteAs i once learnt in my old chevette, going along the M40, "cool, the gauge is reading cold, the overheating problem has disappeared!". Along with it all my coolant. I was young and foolish. Carried on for a couple of miles tho!! Ended up replacing the engine in a cinema car park in high wycombe a few days later...If there's no water the temperature gauge reads cold, since it's measuring the temperature of the coolant.
