  • Cool/Heat: 1953 Commander Coupe Thermostat

    Forgive me for asking what might seem like a dumb question. The shop manual does not appear to state what thermostat is best for my car, and the SI catalog lists 3 - 160, 170, and 180 degrees. My car is running fine although I have no idea what thermostat is in there now; but I want to get a spare for that day when I'll need one. My car has about 17,000 miles on a professionally rebuilt engine, and the engine runs cool. Any thoughts would be appreciated. Thank you in advance.

    I would run the 180. They are all wide open at the temp designed, but engines run a little more efficient at higher temps.

        In the old days we changed thermostats spring and fall. A 160 degree tor summer and a 180 degree for winter. Since we do not us our cars in the winter, I would use a 160 degree thermostat. Newer cars are designed for higher temps. That is not necessarily true for vintage carbureted engines. Vapor lock is enough of a problem nowadays with the crap gas we must use so why increase the opportunity for it??
