FAQ

Q: How do I verify if this nozzle fits my engine?
A: Please compare your original nozzle’s part number (usually stamped on the side) with the numbers listed: DLLA155S365N458, DLLA150S374N464, DLLA150S424N470, or DLLA148S324N473. If your number matches, it is a direct fit. If you are unsure, please contact our support team with your engine model and injector details for verification.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Clean the injector body and nozzle seat thoroughly. 2) Torque the nozzle retaining nut to the manufacturer’s specification (typically 60-80 Nm). 3) Ensure the copper washer is replaced for a proper seal. 4) After installation, prime the fuel system and check for leaks before starting the engine.

Q: How should I store spare nozzles?
A: Store nozzles in a clean, dry environment at room temperature. Keep them in their original packaging to prevent contamination from dust or moisture. Avoid exposing them to corrosive chemicals or extreme temperatures. Proper storage will ensure the nozzles remain in perfect condition for future use.
