Engine Coolant Flow Control Valve

The engine coolant flow control valve is attached under the intake manifold. The engine coolant flow control valve has two actuators, one is the block valve and the other is the control valve. The engine coolant flow control valve consists of two chambers. The first chamber controls the coolant flow rate across the radiator and bypass. The second chamber controls the flow to the transmission and engine oil cooler, providing heated coolant from the EGR/Turbocharger return circuit or cold coolant directly from the pump outlet, as required based on coolant temperature sensor feedback. The Exhaust Gas Recirculation (EGR) feed port is always open.
