BEAT THE
W
hen operating in temperatures above 100°F (38°C), you operators must take
extra care to prevent overheating the vehicle. Overheating starts when the engine
temperature exceeds 230°F (110°C).
• Never operate the vehicle
with the Radiator Fan Off switch
in the ON position. That means
double-check that the engine fan
OFF indicator is
not
lit.
• Never operate the engine longer than 30 sec-
onds at full throttle if the vehicle is not moving.
(For example, while operating the self-recovery
winch or other auxillary equipment.) That
quickly raises transmission oil temperature and
can damage the transmission. Watch the service
indicator light in the shift window. If it lights up,
or if the water temp gauge gets near 230°F
(110°C), the transmission oil is overheating.
•
Watch the water temperature gauge, STOP
engine indicator and High Engine Temperature
indicator closely for signs
of overheating.
•
Check oil levels often
and keep operating strains
as low as possible. Since
the cooling and lubrication
systems support each other,
failure of one system will
quickly lead to the failure
of the other.
•
Check the battery fluid
level often in extreme heat.
Batteries do not hold their
charge well in extreme
heat, so the specific gravity
must be adjusted. See TM
9-6140-200-14 for details.
