2.
If engine does not stall immediately, monitor engine oil pressure for approximately one minute while continuing
with troubleshooting.
CONDITION/INDICATION
Does engine oil pressure reach and/or maintain 8 psi (55 kPa) or greater at engine start up?
DECISION
No - Go to Engine Oil Pressure Gauge Reads Low. (WP 0033)
Yes - Go to step 3. (Step 3 - Does WATER PUMP OUTLET gauge reach or exceed 150 psi (1,034 kPa) or
greater?)
STEP 3
Does WATER PUMP OUTLET gauge reach or exceed 150 psi (1,034 kPa) or greater?
NOTE
Water distributor is equipped with engine protection functions. If water pump outlet pressure
exceeds 150 psi (1,034 kPa), the electronic governor controller will command engine to shut
down.
1.
Raise engine speed to 2000 RPM. (TM 5-3825-270-10)
2.
Observe WATER PUMP OUTLET gauge.

3.
If WATER PUMP OUTLET gauge does not reach or exceed 150 psi (1,034 kPa), do not shutdown engine.
Continue with troubleshooting.
CONDITION/INDICATION
Does WATER PUMP OUTLET gauge reach or exceed 150 psi (1,034 kPa) or greater?
DECISION
No - Go to step 4. (Step 4 - Does ENGINE TEMP gauge read 230F (99C) or higher?)
Yes - Shutdown engine. (TM 5-3825-270-10) Go to Excessive Water Pressure.
STEP 4
Does ENGINE TEMP gauge read 230F (99C) or higher?
NOTE
Water distributor is equipped with engine protection functions. If engine coolant temperature
exceeds 230F (99C), the electronic governor controller will command engine to shut down.
