ABSTRACT:
A cooling system includes: an oil pump for supplying oil under pressure; a cylinder head forming part of a combustion chamber; a cooling portion formed in the cylinder head and adapted to allow circulating oil to cool heat transmitted from the combustion chamber; an oil cooler for cooling oil; and a thermostat for switching between an oil passage routed through the oil cooler and a bypass passage bypassing the oil cooler. The thermostat is disposed in an oil passage between the oil pump and the cooling portion.
