Handwritten: Y766 Y7250 Y7260 Y3875 OVERHEATING - PHANTOM II We suggest that the following information might be given to a customer who complained that his car overheated. The cooling system of the car is designed that under all normal conditions of atmospheric temperature the car will not overheat. Obviously, it would be most extravagant to arrange the cooling system of a car so that it would not overheat, even on the hottest day that could ever be experienced, climbing a hill with a following wind, because this would necessitate in adding a considerable amount of weight to the chassis, which would be carried about by every car to cater for the one exceptional condition. The cooling system of every car is therefore arranged so that it is a compromise. For this reason the temperature of the water in the cooling system will rise to 100°C. if the atmospheric temperature is sufficiently high, since the air temperature ultimately dictates how much heat can be taken away from the radiator. The following points are not generally understood in connection with the car cooling system :- | ||
