6.3 Code 151 - Engine Coolant Temperature High
(Shutdown)
Logic:
Engine coolant temperature has exceeded the alarm (shutdown) threshold for high
coolant temperature.
Possible Cause:
1. High ambient temperature
2. Enclosure air intake blocked
3. Coolant level is below specification
4. Radiator blocked
5. Enclosure air discharge blocked
6. Fan belt is broken or loose
7. Coolant level is below specification
Diagnosis and Repair:
1. High ambient temperature
a. Reduce loads or recirculation of discharge air to generator in elevated
ambient.
2. Enclosure air intake blocked
a. Inspect for dirt, debris, or obstructions.
b. Remove blockage or snow/ice buildup as applicable.
3. Coolant level is below specification
a. Check coolant level.
b. Add coolant as necessary
4. Radiator blocked
a. Inspect for dirt, debris, or obstruction.
b. Remove blockage or winterfront as applicable.
5. Enclosure air discharge blocked
a. Inspect for dirt, debris, or obstructions.
b. Remove blockage or snow/ice buildup as applicable.
6. Fan belt is broken or loose
a. Inspect belt(s) for damage, wear, and proper tension.
