FAQ

Q1: How can I verify if this cylinder liner fits my specific Nissan K21 or K25 engine?

We recommend verifying the casting number on your old cylinder liner. The primary reference numbers are 12010-fu400 and 12010-fu420. Additionally, measure the liner’s outer diameter, inner diameter, and flange height to ensure it matches your engine block specifications. If you are unsure, please contact us with your engine serial number for confirmation.

Q2: What is the proper installation procedure for this cylinder liner?

Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the cylinder block bore. 2) Applying a suitable liner sealant (e.g., Loctite) to the outer surface of the liner. 3) Using a hydraulic press or a specialized liner installation tool to press the liner into the block. 4) After installation, a final hone may be required to ensure the correct cross-hatch pattern for piston ring seating. Always follow the engine manufacturer’s service manual.

Q3: What maintenance is required after installing a new cylinder liner?

After installation, the engine must be properly broken in. Avoid operating at full load for the first 50-100 hours. Use the recommended grade of engine oil and change it according to the service schedule. Regularly check coolant quality to prevent cavitation corrosion on the liner’s outer wall. Monitoring oil consumption and performing periodic compression tests will help ensure the liner’s longevity.
