Abstract: An engine system with a coolant control valve includes: a valve housing having a first valve space and a second valve space formed at both sides by a partition and including a connection passage formed in the partition; a first rotary valve disposed in the first valve space and having first coolant passages; a second rotary valve disposed in the second valve space and having second coolant passages; distribution lines respectively connected to positions corresponding to the first coolant passages and the second coolant passages and distributing the coolant coming through the first rotary valve and the second rotary valve; and a driver to rotate the first rotary valve and the second rotary valve. In particular, the first and second coolant passages are connected to the connection passage depending on the rotation positions of the first rotary valve and the second rotary valve.
