FAQ

Q1: How can I confirm this nozzle (DOP140S435-4369) fits my engine?
A: Please check the number stamped on your old nozzle. It should match DOP140S435-4369 or DLLA150S883. This is an S-Type (size 21) nozzle with a 150-degree spray angle. If your old nozzle has these markings and the same physical dimensions (length and diameter), it will be a direct fit. If unsure, please contact us with a photo of your old part.

Q2: What is the recommended installation procedure for this injector nozzle?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Clean the injector body thoroughly to prevent dirt ingress. 2) Replace the nozzle retaining nut and copper sealing washer with new ones (not included). 3) Torque the nozzle retaining nut to the manufacturer’s specification (typically 70-90 Nm for S-type nozzles). 4) After installation, bleed the fuel system to remove air before starting the engine.

Q3: What is the difference between the DOP140S435-4369 and other similar nozzles?
A: The primary difference lies in the specific spray hole configuration (number, diameter, and angle) which is defined by the DLLA150S883 code. This code determines the fuel flow rate and spray pattern optimized for specific combustion chambers. Using the exact OEM-matched number ensures correct fuel delivery and prevents issues like misfiring, black smoke, or excessive fuel consumption. Using a generic “universal” nozzle can damage your engine.
