To: All Chevrolet Dealers:
In cases where both erratic and high temperature readings are being encountered on 1956 Passenger Cars during the "warm-up" period, the condition may be reduced by the installation of a 10 ohm-5 watt WIRE WOUND resistance in series with the sender unit located in the cylinder block.
The procedure for installing this 10 ohm resistor most satisfactorily is as follows:
Practice or removing the radiator pressure caps to correct this condition should be discontinued, as this reduces the overall cooling efficiency of the unit.
