If the engine temperature indicator suddenly rises to "HOT" position, stop the engine Immediately, and
check for cause of overheating. Notify organizational maintenance.
1.
After engine starts, check oil pressure gage (1) and water temperature (2). Make sure oil pressure gage Is
indicating 10-25 psi (69-172 kPa) and water temperature gage shows a slow rise.
2.
Increase engine idle to 750800 rpm by adjusting throttle control (3), and observing tachometer (4).
3.
Check ammeter gage (5). It should show a slight charge rate.
4.
Allow engine to warm up for at least 15 minutes, air pressure gages (6) and (7) to indicate 90 psi (621 kPa)
and low air pressure warning indicator light (8) to go out.
5.
After engine is thoroughly warmed up, place the transmission range selector into D5 and drive slowly for
about 100 yards (91.4 m). Be careful not to stall the engine. This should heat gears and tires enough for the
truck to be ready for normal operation.
