What is the device that sits between the radiator and the engine, regulating the flow of coolant to the engine?
Answer Thermostat
The thermostat regulates the flow of coolant from the radiator to the engine, closing off the flow until the engine has reached its operating temperature. Once reached, the thermostat releases the coolant into the engine.
