FAQ

Q: How do I confirm the correct nozzle type (G374, H374, L374) for my engine?
A: You must physically inspect your existing injector nozzle. The specific part number (e.g., G374PBD, H374PRD, L374PBD) is typically stamped on the nozzle body. Cross-reference this number with our list to ensure you order the correct component. Using the wrong nozzle type can lead to poor performance or engine damage.

Q: What is the installation procedure for these common rail nozzles?
A: Installation should be performed by a qualified diesel technician. The process involves removing the old injector, carefully cleaning the injector bore in the cylinder head, installing the new nozzle with a new sealing washer (not included), and tightening the injector clamp to the manufacturer’s specified torque. The common rail system must then be primed and checked for leaks.

Q: What is the typical lifespan of these nozzles and what are signs of failure?
A: Lifespan varies based on fuel quality, maintenance, and operating conditions, but they are designed for long-term durability. Common signs of a failing nozzle include rough idling, increased fuel consumption, black smoke from the exhaust, loss of engine power, and hard starting. Regular replacement of fuel filters is critical to maximizing nozzle life.
