FAQ

Q1: How do I confirm this oil cooler fits my Nissan BD30 engine?

We recommend verifying your existing part number against our cross-reference (21010-40K25 or 21010-40K26). Additionally, you can check the physical dimensions and mounting pattern of your current oil cooler. If you have a specific equipment model (e.g., TCM forklift or Nissan Diesel engine series), please contact our sales team with your machine’s serial number for confirmation.

Q2: What are the signs that my oil cooler needs replacement?

Common indicators include visible oil leaks around the cooler, mixing of oil and coolant (milky appearance), elevated engine oil temperature readings, or a drop in oil pressure. Regular inspection during oil changes is recommended, especially in high-hour equipment operating in dusty or hot environments.

Q3: What maintenance is required after installing a new oil cooler?

After installation, ensure the cooling system is properly bled of air and check for leaks at all connection points. Run the engine to operating temperature and verify oil pressure and temperature are within normal ranges. We recommend replacing the engine oil and filter at the same time to prevent contamination from the old system.
