(4) Engine over-speed protection
The engine is protected against over-speed by a speed-limiting mechanism in the mechanical
governor.

The engine fan is designed to blow air outward through the radiator, rather than pull the air

Refer to the engine Operation and Maintenance Manual in Chapter 5 for more engine details.
