ENGINE COOLING AND AIR INDUCTION — ALL CARRIERS

Air for engine combustion and cooling is drawn through the intake grille and radiator. Air sweeps down around the power

plant and out through the exhaust grille above the fan. An air control valve allows driver a choice of drawing air from the rear

compartment or power plant compartment for the engine. During operation, air in the power plant compartment warms up

(becomes less dense). Drawing cooler (more dense) air from the rear compartment gives the engine a boost in horsepower.

When the vent is open to draw from the crew compartment, less air is being drawn through the radiator. In hot climates, it

should only be opened for short periods. The air cleaner is equipped with a restriction indicator to inform the driver when the

air cleaner element needs cleaning.

WARNING

Failure to open ventilator, when operating carrier with all hatches closed, will result in a serious

lack of oxygen.

CAUTION

Avoid overheating of components during operation. Keep power plant door, access plates,

and panels closed tightly for correct air flow.
