FAQ

Q: How do I confirm this nozzle fits my injector?
A: Check the existing nozzle for the stamped code. It must read “DLLA155P683” or “093400-6830”. This nozzle is designed for DENSO injector assemblies 095000-1030 and 095000-1031. If your injector body does not match these numbers, please provide a photo or the full part number for cross-verification.

Q: Can I replace just the nozzle instead of the entire injector?
A: Yes, provided the injector body (valve, solenoid, and piston) is in good condition. We recommend cleaning the injector body thoroughly and replacing the nozzle holder gasket (sold separately) during installation. This is a common, cost-effective repair in diesel workshops.

Q: What is the installation procedure for this nozzle?
A: Installation requires specialized tools to avoid damaging the precision surfaces. The process involves: 1) Removing the old nozzle. 2) Cleaning the injector body bore. 3) Installing the new nozzle with proper torque (typically 40-50 Nm). 4) Reassembling the injector. We recommend professional installation by a qualified diesel technician. Incorrect installation can lead to poor performance or engine damage.
