ABSTRACT:
A coolant temperature control system of an internal combustion engine is composed of a thermostat disposed in a coolant passageway leading to a radiator. The thermostat is operatively connected to a diaphragm actuator so that valve opening temperature of a thermostat valve is controlled in response to engine loads. Additionally, the thermostat valve is arranged to be opened in response to the discharge pressure of a coolant pump, thereby lowering the opening temperature of the thermostat valve at a high speed engine operating range.
