Should you encounter Model “A” cars or “AA” trucks that are overheating, always check the radiator splash plate to make certain it has been changed in accordance with instructions given on page 450 in the April 1930 Service Bulletin, also check the timing. Should the water in a radiator be allowed to get very low, causing a car or truck to overheat, always allow it to cool off a little before pouring cold water into the radiator, or keep engine running.
