content is sufficient for the existing ambient
temperature. (Refer to the manufacturers manual for
the type and quantity of antifreeze. Add antifreeze as
required.) Check the hoses and clamps for security.
condition and tightness at the seams and at the point of
coupling near the housing.
4. Batteries. Check the batteries for the required
electrolyte level; add distilled water or, if distilled water
is not available, clean tap water as required to raise the
electrolyte level to the slots in the filler wells.
7. Alternator (fig. 3-16) and belts. Inspect the
alternator for signs of overheating, frayed or loose
wiring, and corrosion. Inspect the alternator drive belts
and fan belts for proper tension and for cracks, fraying,
and other signs of deterioration.
5. Air intake system. Check the air intake system
cleaner for excessive dirt (see AIR CLEANER PANEL
FILTER, fig. 3-15); remove and clean the air cleaner
panels as required. Check the air intake louvers and
radiator grille for freedom of motion, and ensure that
they are not clogged.
8. Breather. Inspect the breather extension for
tightness, general condition, and leakage. Check that
the breather coupling is not restricting the flow of air
and that the breather exit port is clear.
9. Fuel system. Inspect the electric fuel transfer
pumps for secureness, tight fittings, signs of damage,
corrosion, leaks, and loose electrical connections.
6. Exhaust extension. Inspect the exhaust
Look over the fuel filters and strainers for leaks and
extension (where extended through the roof or wall) for
tight fittings. Drain water and sediment from the
