Common Engine Fault and Solution in Construction Machinery
Engine Overheating
Symptom: The engine temperature gauge shows a reading significantly higher than normal, and steam might be visible coming from under the hood.
Possible Causes:
- Low coolant level: Check the coolant reservoir and radiator.
- Faulty thermostat: The thermostat might not be opening to allow coolant flow.
- Radiator issues: The radiator might be blocked internally or externally with debris.
- Water pump failure: The water pump might not be circulating coolant effectively.
- Loose or broken fan belt: The fan belt drives the cooling fan.
Troubleshooting Steps:
- Safely stop the machine and turn off the engine. Allow it to cool down before attempting any checks.
- Check the coolant level in the radiator and reservoir. If low, add the appropriate coolant mixture.
- Inspect the radiator for any external blockages (e.g., dirt, debris). Clean it carefully.
- Check the condition and tension of the fan belt. Replace it if it's loose, cracked, or broken.
- If the problem persists, it might indicate a faulty thermostat or water pump, requiring professional inspection and replacement.
