Engine Cooling

Cooling is accomplished by means of a blower, consisting of an impeller and blower housing. Center of blower housing holds support for alternator. Impeller and belt pulley are attached to alternator shaft.

Blower delivers air required for cooling engine, oil cooler, alternator as well as fresh air for heating system. Cooling air flows through upper molded plastic air guides to cylinders and heads.

Baffle plates provide uniform distribution of air. A duct incorporated into upper air guide leads air flow directly to oil cooler. Ducting for air delivery to heat exchangers is on both sides of blower housing.

Adjustment of blower drive belt is done by adding or removing spacers between impeller housing and pulley half. This will cause belt to ride higher or lower on pulley, thereby loosening or tightening drive belt.
