How to Fix / Troubleshooting
Safety first: Allow the engine to cool before touching engine components. Do not run with suspected lubrication issues.
- Check oil level and quality: Top up to the correct mark with specified oil. If oil is very dirty or degraded, perform an oil and filter change.
- Inspect oil cooler: For engines with an external oil cooler, ensure fins are clean and coolant or air flow is not obstructed.
- Sensor inspection: Locate the oil temperature sensor and check wiring. Replace the sensor if readings are clearly abnormal.
- Reduce load: Confirm the generator is not being overloaded. Reduce load to within nameplate rating.
- Professional diagnosis: Persistent high oil temperature may indicate internal engine problems; consult an engine specialist.
