The Stovebolt Site Forums The Shop Area General Truck Talk Thermostat,no thermostat, that is the question

you need the tremostate for every day street use. a 235 engine is not ment to run at 200. a 165 may be too cold. thermostat keeps the engine at a uniform temperature. i would try a 170 if they still make them. higher temp means higher pressure on the cooling system. use a new cap. most engines have a cast in termostae by pass chanel of some sort. all modern thermostates have an air relise 'hole' about 1/16 or less.
