Quick Tips for Excavator Maintenance
Regularly Inspect Hoses: Check all hoses (air, water, hydraulic) for cracks, leaks, and wear. Replace damaged hoses immediately to prevent system failures. This includes Air Hose and Cooling Hose.
Monitor Fluid Levels: Regularly check and maintain proper levels of engine oil, hydraulic oil, and coolant. Use Fuel Water Level Sensor to ensure accurate readings.
Check Electrical Connections: Inspect relays, solenoids, and wiring harnesses for corrosion or damage. Ensure secure connections for optimal electrical system performance. Replace faulty Relay or Wiring Harness as needed.
Troubleshooting: Excavator Engine Overheating
Problem: Excavator engine temperature gauge reading high, steam or coolant leaks, engine power loss.
Possible Causes & Solutions:
Low Coolant Level: Check coolant level and refill if low. Inspect for leaks in Cooling Hose and radiator.
Faulty Thermostat: Thermostat may be stuck closed, preventing coolant circulation. Replace thermostat.
Radiator Blockage: Check radiator for external debris or internal corrosion. Clean radiator externally and flush cooling system if necessary.
Water Pump Failure: Water pump may not be circulating coolant effectively. Inspect and replace water pump if needed.
Air in Cooling System: Air pockets can reduce cooling efficiency. Bleed air from the cooling system.
If overheating persists after these checks, consult a qualified technician.
