ENGINE CHECK INDICATOR LAMP OR LAMPS ARE ON.
Step 1. Check indicator lamps (1). Lamps indicate a potential engine failure (low oil pressure, low coolant,
coolant overheating) has occurred.
Check gages and shut down engine. Gages should read as follows:
Oil pressure 10 psi (69 kPa) at idle; Water Temp gage below 203 degrees F (95 C).
Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading add oil and
recheck gage. If condition still exists, notify Unit Maintenance.
Check coolant level (Para 2-11) if Water Temp gage indicates high reading, add
coolant (Appendix G) and recheck gage. If condition still exists, notify Unit Maintenance.
Step 2. If LO OIL PRES lamp (2) is on, check engine oil pressure gage (3) and if HI ENG TEMP (4) is on
check water temperature gage (5). If both indicate normal, proceed with mission and then notify
Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify
Unit Maintenance.
