ABSTRACT:
A cooling system for a V-type engine includes a radiator, having inlet and outlet conduits extending between the radiator and the engine, which cools coolant introduced therein through the inlet conduit, and a water pump with an inlet port, disposed between the engine body and the radiator, which circulates the coolant, leaving the radiator through the outlet conduit, through the engine body. Between the radiator and water pump, the cooling system is provided with a bypass passage, which communicates a passage, connecting both of the outlet ports to the inlet conduit, with a downstream part of the outlet conduit where a thermostat is installed, and a suction passage which communicates the inlet port of the water pump with the downstream part of the outlet conduit by a suction passage. The suction passage comprises an external passage, constituting an upstream portion thereof, which is disposed in the V-shaped space, and an internal passage, constituting a downstream portion thereof, which is formed in the engine body below the V-shaped space.
