FAQ

Q: Is this oil cooler a direct fit for my Komatsu PC120 excavator with a 4D31 engine?
A: Yes, this oil cooler is designed as a direct replacement for the 4D31 engine, which is commonly used in Komatsu PC120 series excavators. However, we recommend comparing your original part’s dimensions with the specifications provided (weight: 1.65 kg) to ensure a perfect match.

Q: How do I install this oil cooler?
A: Installation should be performed by a qualified mechanic. Typically, you need to drain the engine coolant and oil, disconnect the old cooler lines, remove the mounting bolts, and replace it with the new unit. Always replace gaskets and O-rings during installation to prevent leaks.

Q: What maintenance is required for this oil cooler?
A: Regular inspection of the oil cooler for external damage, debris buildup, or leaks is recommended. Ensure the cooling fins are clean for optimal airflow. The cooler itself is a robust component; however, if the engine overheats frequently, check the cooling system and oil quality to prevent premature failure.
