35. During conditions of high ambi-
ent temperatures (85°F or
above), the coolant temperature
may exceed 200°. If the cool-
ant temperature exceeds 200°F,
under these conditions, the oper-
ator will reduce vehicle speed to
determine if the high ambient
temperature is causing the
higher engine coolant
temperature.
36. If after operating the vehicle at
reduced speed the engine coolant
temperature does not decrease,
stop the engine, check the
coolant level (page 3-43), and
follow overheating
troubleshooting procedures
(page 3-7). Normally the
temperature wont go below
160°F once the engine warms
up, unless you have to idle in
artic temperatures (below -25°F
(-32°C)).
37. If the coolant temperature drops
to 140°F (60°C), run the engine
at 1200-1500 rpm until it
warms up. If the temperature
gage doesnt work, report it to
organizational maintenance.
