"Warn-O-Meter" Motometer & Radiator Cap, circa 1923
Add to SetSummary
Automobiles often came without temperature gauges before the early 1930s, so enterprising manufacturers sold aftermarket motometers. Mounted on a car's radiator, these devices measured and displayed coolant water vapor temperature, notifying drivers if their automobiles were in danger of overheating. Stewart-Warner Speedometer Corporation produced this "Warn-O-Meter" motometer in Chicago around 1923.
