Abstract
An engine having a coolant control valve may include a sealing ring including a sealing ring inlet and sealing ring outlets, a valve housing to rotatably house the sealing ring therein, wherein discharge outlets are formed corresponding to the sealing ring outlets, a drive portion coupled to the sealing ring to selectively rotate the sealing ring, and a blocking wall that is disposed to the one end portion of the sealing ring to block a part of the one end portion of the sealing ring to form the sealing ring inlet, wherein the blocking wall is selectively rotated about a central axis thereof in accordance with a rotation of the sealing ring, wherein the blocking wall selectively blocks a first coolant line of a cylinder head or a second coolant line of a cylinder block depending on a rotation position of the sealing ring.
