FAQ

Q: How do I verify if the 0433171257 / DLLA147P360 is the correct nozzle for my injector?
A: You must first remove the old nozzle from your injector body. The part number (0433171257) and the nozzle code (DLLA147P360) are typically laser-etched on the side of the nozzle. Compare these numbers directly with our listing to ensure a perfect match. If you are unsure, please contact us with your injector or engine model number.

Q: What is the installation procedure for this nozzle?
A: Installation should be performed by a qualified diesel technician. It requires specialized tools to clean the injector body seat, install the new nozzle with a new copper washer, and torque it to the manufacturer’s specification. After installation, the injector’s opening pressure must be tested on a pop tester to ensure it is within the correct range (typically 260-280 bar for this type). Incorrect installation can lead to engine damage.

Q: What is the typical lifespan of this injector nozzle?
A: The lifespan depends heavily on fuel quality, engine maintenance, and operating conditions. With clean fuel and regular filter changes, this high-quality nozzle can last for 100,000 to 150,000 kilometers or more in a heavy-duty truck application. Poor fuel quality or contaminated fuel will significantly reduce its service life.
