paka40, your comment confuses me. The 1935-1941 Packard Master Parts List clearly shows a cylinder head thermostat for the 1940 110, the listing is the same as HH56 posted earlier in this thread. Are you perhaps confusing a cylinder head thermostat with a Sylphon shutter-stat? They are both thermostats for the purpose of regulating engine temperatures, one regulates by controlling coolant flow, the other by regulating air flow thru the radiator. In some years and models both are employed, in others just one or the other.
