The 160 opens at 160 and stays open. The purpose of the thermostat is to allow the coolant to sit in the radiator long enough to cool and then the thermo re-opens and lets the cooled coolant into the engine. When you have no thermo or a low open temp one the coolant flows all the time. it flows through the radiator so quickly that it does not cool down and returns to the engine still hot. Removing the thermostat is one of the most common "stupid" things to do. John
