Thermostat – early model Dole type OEM (includes thermostat gasket)

These thermostats are for use in engines with original early model cooling systems.  They will typically maintain temperature in the range of 150 to 160 degrees depending on condition of cooling jackets and temperature of raw water.  During warm-up, reduced flow through the exhaust system may result in a little steam coming out with the exhaust.
