A cooling apparatus for an engine includes an oil warmer, an engine internal passage, a warmer passage, a water pump, and a thermostat. The warmer passage connects an outlet of the internal passage to an inlet of the internal passage. The thermostat regulates an amount of coolant that flows into the oil warmer. The thermostat includes a valve member, a body, and a plurality of types of wax. The thermostat determines a degree of opening of the valve member in accordance with amounts of expansion of the respective types of wax caused by melting of the respective types of wax. The types of wax include a first wax, which melts at a first temperature, and a second wax, which melts at a second temperature which is higher than the first temperature.
