I think the reason they used to recommend changing to a higher temperature thermostat in the winter was to make the heater work better.

That recommendation is given in the Packard service manuals of the 30s, and for that reason. To quote from the 1937 110/129 shop manual, "These cars have cylinder head thermostats only. Thermostats marked 147 degrees are standard but units marked 162 degrees are available for temporary use with hot water heaters. The 162 degree thermostat is not suitable for use with alcohol antifreeze."
