How.CadillacT Helps Cold Weather Motoring Every motorist who operates his car in winter knows the annoyance of the "warming up" period which must follow starting the engine after it has stood overnight in a cold garage or for several hours on the streeL So the device on the Cadillac Eight which facilitates warming up is of interest in-terest to all motorists. This device exercises a thermostatic control over the fluid In the cooling system and, like many other motor car developments, was inaugurated by the Cadillac Company. The thermostats, thermo-stats, of which there are two one for each block of cylinders operate in connection with valves which open and close as the thermostats expand and contract with heat and cold. When the engine and radiator are cold, the valves are closed and the water in the radiator is practically cut off from that in the water jackets of the cylinders. After the engine is started, the liquid surrounding the cylinder blocks rises in temperature and the thermostat valves open slowly. Without the thermostat, all the liquid in the cooling system would have to be heated before the engine would have to be heated before the engine would run well, whereas with the thermostats, only a small quantity has to be warmed at the outset, and the thermostat valves admit the water from the radiator as the temperature of the fluid rises. The device is wholly automatic in its action. It enables the engine to reach its highest efficiency much more quickly than would be possible if it were necessary to heat the entire volume vol-ume of circulating fluid before that efficiency were obtained.
