Compatibility

This Common Rail nozzle is designed for a universal fitment in various diesel engines. While it is commonly used in automotive and light industrial applications, it is critical to verify the specific nozzle code (DLLA158P909) against your engine’s injector specifications. Typical applications include:

• Diesel engines requiring Bosch-style injector nozzles
• Common Rail fuel injection systems
• Compatible with many European and Asian passenger car and light truck diesel engines.

Note: Always confirm the part number on your original injector before ordering. This is a nozzle-only component; professional installation is recommended.

FAQ

Q1: How do I confirm if the DLLA158P909 nozzle fits my engine?
A: You must physically check the part number stamped on the side of your existing injector nozzle. The number must match DLLA158P909 (or its cross-references like 0 433 171 158). This is the most reliable method, as engine models can use different injector variants.

Q2: What is the installation procedure for this nozzle?
A: Installation should be performed by a qualified diesel technician. Key steps include: 1) Carefully cleaning the injector body and nozzle recess. 2) Replacing the nozzle retaining nut with a new one (recommended). 3) Torquing the nut to the manufacturer’s specification. 4) Testing the injector for correct opening pressure and spray pattern on a test bench before re-installation.

Q3: What is the typical lifespan of this high-speed steel nozzle?
A: Lifespan depends heavily on fuel quality, engine maintenance, and operating conditions. Under normal conditions with clean fuel and proper oil changes, a high-quality nozzle can last 100,000 to 150,000 kilometers (approx. 60,000 to 90,000 miles). Contaminated fuel or poor maintenance will significantly reduce its service life.
