Thermostats used in a Model A, that are installed without a by pass, could create a problem with your water pump.

Potential for oil flash on cylinder walls and hot spots with boiling.

The higher you are above sea level, the more likely you could see a problem with boiling.

Even a 160 degree thermostat might not be fully open until coolant reaches +180 degrees.

Google “Rocky Mountain Model A Club Cooling System Seminar ” good info.

Sorry if my comments offend anyone. I feel very strongly on a couple of things that have to do with these cars and a thermostat is one of them. Enjoy.

hey old timer. don't be afraid to speak. that's how young blokes learn and that's even how old blokes ( like me) also learn.
