Troubleshooting
2Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Low Oil Pressure Shutdown | Low oil level, Oil leaking from engine, Oil pressure sender | Check oil level on dipstick. Add oil if needed. Visually inspect the engine for leaks. Restart unit and verify loss of pressure. Shut down immediately if pressure does not reach 5 psi (34 kPa) within five seconds. See engine operator’s manual to identify corrective action. |
| High Coolant Temperature Shutdown | Low coolant level, Blockage in radiator, Leakage in coolant hoses, engine block, or water pump | Add coolant if needed. Allow engine to cool, then check coolant level in radiator. Check radiator shroud and ducting for blockage and remove any foreign matter. Inspect for visible leaks. Check tension of water pump serpentine drive belt. Remove load on generator and restart engine.
