Abstract
An engine cooling apparatus includes a cooling water outlet communicating with a water jacket provided in a cylinder block and a cylinder head provided on an intake port side of the cylinder head. A thermostat switches a path for cooling water discharged from the cooling water outlet, according to a cooling water temperature. A thermostat case for the thermostat is disposed downward of a line L extended from a coupling surface between a cylinder block and a cylinder head. The thermostat case and the cooling water outlet are connected via a connecting pipe. This arrangement makes it easy to secure a space for disposing the thermostat.

An engine cooling apparatus comprising:
- a cooling water outlet that communicates with a water jacket provided in a cylinder block and a cylinder head, said cooling water outlet being provided on an intake-ports-side of the cylinder head;
- and
- a thermostat to switch, according to a cooling water temperature, a path for cooling water discharged from the cooling water outlet, that is connected to the cooling water outlet,
- wherein a thermostat case for the thermostat is disposed in its entirety downward of a line extended from a coupling surface between the cylinder block and the cylinder head, and
- the thermostat case and the cooling water outlet are connected via a connecting pipe.
