FAQ

Q: Is this oil cooler core a direct replacement for my Mitsubishi 4D31 engine?
A: Yes, this part is specifically manufactured to be a direct replacement for the oil cooler core in the Mitsubishi 4D31 diesel engine. It is designed to match the original dimensions and mounting points. We recommend verifying your current part number against our specifications to confirm 100% compatibility with your specific machinery model.

Q: What is the recommended maintenance procedure after installing a new oil cooler core?
A: After installation, ensure the system is properly bled of air. Fill with the correct grade and quantity of engine oil. Start the engine and check for any leaks around the oil cooler connections. Monitor the oil temperature during the first few hours of operation to ensure the cooler is functioning correctly. We also recommend replacing the engine oil filter during this service for optimal results.

Q: Can this oil cooler core be used in high-temperature or heavy-load applications?
A: Yes, this core is designed for the demanding conditions of construction machinery, which often involve high loads and ambient temperatures. Its construction from high-grade materials ensures efficient heat dissipation, helping to maintain stable oil temperatures even under heavy stress. For extreme conditions, ensure your engine’s cooling system (radiator, coolant, fan) is also in good working order to support the oil cooler’s performance.
