Reply To: 1931: Shutters Or Thermostat?

Greg is correct, running the engine too cool advances engine wear by 200 to 300 percent…….. but todays modern oils, valves, pistons, and rings are much better than fifty to ninety years ago. The block on a Pierce is very good material and doesn’t offer any issues. Running the thermostat as Greg does is fine, EXCEPT today the cheap thermostats available are just terrible quality so be sure and buy one from a speed shop that sells ones made in the USA. They run about 25 bucks, and are worth every penny.
