FAQ

Q1: How do I confirm this nozzle fits my engine?
A: Verify the part number DLLA176S324NP80 or OEM 105015-3590 against your engine’s service manual or injector body markings. If unsure, contact us with your engine model and serial number for confirmation.

Q2: What is the installation procedure for this nozzle?
A: Installation should be performed by a qualified diesel technician. The nozzle must be fitted into the injector holder using proper torque specifications, and the injector should be bench-tested for pop pressure and spray pattern before reinstallation.

Q3: How often should diesel injector nozzles be replaced?
A: Replacement intervals depend on fuel quality and operating conditions. Typically, nozzles should be inspected every 1,500–2,000 hours and replaced when spray pattern degrades, fuel consumption increases, or engine performance declines.
