Abstract
A piston cooling apparatus for a vehicle, includes: a first gallery that is formed at one side of a cylinder block in a length direction, and receives an oil from an oil pump; a second gallery that is formed at the other side of the cylinder block in a length direction, and supplies the oil into piston cooling jets; and a solenoid valve that is disposed at one side of a hydraulic line of the second gallery. In particular, the solenoid valve bypasses the oil supplied from the first gallery and selectively supplies the oil to the second gallery.
