A method of cooling an engine of a vehicle includes measuring a temperature of a cylinder head of the engine, determining whether the measured temperature of the cylinder head may be equal to or lower than a predetermined temperature, when the temperature of the cylinder head may be equal to or lower than the predetermined temperature, moving coolant of the cylinder head and a cylinder block to a separate coolant tank, determining whether the measured temperature of the cylinder head may be equal to or higher than a specific temperature, and when the measured temperature of the cylinder head may be equal to or higher than the specific temperature, supplying coolant stored in the coolant tank to the cylinder head or the cylinder block.

Included may be a crankshaftless internal combustion engine, including a power shaft unit in which a transferring path of a power system may be selected depending on a deactivated state and an activated state of a cylinder, a cylinder separator separating a power system of the deactivated cylinder from the power shaft unit by control of an ECU operated by a deactivated cylinder and an activated cylinder, and a compression changing unit varying a compression ratio of the activated cylinder in multistage.
