Abstract
A V-shaped engine has an inlet passage and an outlet passage for coolant. The inlet passage for introducing coolant to a water pump mounted to a front face of a cylinder block of the engine is arranged vertically in a space between a right bank and a left bank. The outlet passage is so arranged as to pass between a timing belt idler provided forwardly of the space between the right bank and the left bank and the inlet passage. This arrangement of the inlet passage and the outlet passage enables the V-shaped engine to be made compact.
