I had a 1928 Chevrolet Sport Coupe and used it as an everyday car for a number of years. Besides the water pump, it bears mentioning that the '28 Chevy came standard with a 'Honeycomb' radiator. I never had any cooling troubles with my '28 Chevy. But then, I lived along the cool Pacific Coast, where cooling problems were rarely an issue, unless climbing over the Santa Cruz mountains to reach the fun-filled sands of the Pacific beaches. Of course in those days you never went anywhere without a 2 gallon 'Desert' canvas (flax) water bag strapped to your front bumper.
