Possible Causes
Coolant leak at hoses or radiator, loose hose clamps, failed radiator cap, internal head gasket leak
How to Fix / Troubleshooting
Safety first: Never open a hot cooling system. Turn the controller to OFF, open the main AC breaker, disconnect the negative battery cable, and allow the engine to cool completely.
- Check coolant level: Remove the radiator cap slowly once cool. Top up with the correct coolant mixture to the specified level.
- Inspect for external leaks: Examine all hoses, clamps, radiator seams, and the water pump area for dried coolant residue or wet spots. Tighten clamps and replace cracked hoses.
- Check radiator cap: Inspect the cap seal and spring. Replace the cap if it appears worn or damaged.
- Monitor coolant loss: After refilling, run the generator and monitor coolant level over several hours of operation. Rapid loss may indicate an internal leak requiring professional service.
