Re: Engine upgrade
Good Morning...When the Model A was designed, the engineers lived in Detroit and the surrounding area...so they designed a cooling system that met with their experience. Cars coming to the southwest always seemed to have 'heavy duty' option radiators ordered for them. Also, at least in Southern California and Arizona where I have mostly lived...radiator shops have specialized in building larger radiators for all sorts of cars and trucks...also thermostats...a well tuned Model A will run at different temperatures in different parts of the county at different times of the year. On a cold winter day, maybe 130 or so, on a hot summer day, in the southwest 190 or even 200 was not uncommon. With a bigger radiator and a thermostat...160 to 180 can be maintained, the engine is pretty much happier at 160 in my humble driving experience. Ernie in Arizona
