PROBLEM TO BE SOLVED: To provide a cooling device for multiple engines in which temperature of air blown from a heat exchanger for air conditioning is stabilized regardless of operation states of a main engine and a subsidiary engine. SOLUTION: This cooling device 1 is provided with a first, a second, and a fourth cooling water passages 80, 82, and 86 to send cooling water from the main engine 10 through a radiator 72 to the subsidiary engine 20, a third, and the fourth cooling water passages 84 and 86 to send cooling water from the main engine 10 to the subsidiary engine 20 without passing through the radiator 72, a thermostat 70 to communicate the third cooling water passage 84 with the fourth cooling water passage 86 while disconnecting communication between the second cooling water passage 82 and the fourth cooling water passage 86 in a case of temperature of cooling water of a second prescribed value or less, and a fifth and a sixth cooling water passages 88 and 90 to circulate cooling water from the subsidiary engine 20 through a heater core 76 to the main engine 10.
