A cooling system has a first passage communicating an outlet of water jackets with an inlet of a radiator, a second passage communicating an outlet of the radiator with an inlet of a water pump, and a bypass connected between the first passage and a thermostat housing. A thermostat comprising a thermo-sensitive device and a valve is disposed in the second passage, so that the valve closes the second passage. The thermo-sensitive device is disposed in the bypass, so that the thermo-sensitive device is exposed to coolant passing the bypass.
