Abstract
A coolant control valve that selectively supplies an EGR cooler with coolant may include a cylinder head having a first water jacket and a second water jacket, an EGR cooler that is disposed at one side of the cylinder head and is disposed on an EGR line that recirculates exhaust gas from an exhaust side to an intake side, a heater that is disposed at another side of the cylinder head and heats air through coolant that is supplied to the heater, and a coolant control valve that respectively controls coolant that is supplied from the first water jacket and the second water jacket, supplies the heater with the coolant, and selectively supplies the EGR cooler with the coolant depending on a temperature of the coolant.
