**Diagnosis & Solution:** Persistent engine overheating in a Komatsu PC300-7 6D107 often stems from a failing **Water Pump** or a cracked **Cylinder Head**. First, check the coolant level and radiator for leaks. If these are fine, inspect the Water Pump bearing for play or leakage. Replace the **Water Pump** if failure is detected.
**General Maintenance:** To prevent future issues, perform a full engine oil and filter change (using high-grade oil) every 250 hours. Regularly inspect the tension and condition of the **Belt** and flush the cooling system annually.
Honour Time Machinery Limited is a dedicated **source manufacturer** specializing in high-quality engine assemblies and replacement spare parts for major brands like **Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai**, serving the global heavy equipment market.
