REFERENCE INFORMATION
ENGINE COOLING SYSTEM
Refer to TM 5-3895-373-10 for engine starting and equipment operating procedures. Refer to paragraph
2.10 for connecting and disconnecting STE/ICE-R test set to DCA. Refer to paragraph 1.17 for engine
cooling system operating principles.
Check engine temperature at gauge
panel.
STE/ICE-R test 38 will confirm the
operating temperature of the engine.
To
verify
accuracy
of
panel
temperature gauge, check results of
STE/ICE-R test against panel gauge
reading.
