FAQ

Q1: How do I verify this injector fits my engine?

Check your existing injector for the part number stamped on the body. The numbers RE558869 or 295050-1380 must match exactly. Also confirm your engine uses a DENSO common rail system (look for HP0, HP3, or HP4 pump markings). Different engine calibrations require specific injector codes – do not substitute without verification.

Q2: What installation precautions should I take?

Always replace injector copper washers and O-rings with new ones (sold separately). Clean the injector bore thoroughly before installation. Torque injector hold-down bolts to manufacturer specifications (typically 70-90 Nm). After installation, perform a leak-off test to ensure proper sealing. We recommend professional installation by a qualified diesel technician.

Q3: How should I maintain these injectors for maximum lifespan?

Use high-quality diesel fuel with proper cetane rating. Replace fuel filters at recommended intervals (every 10,000-15,000 km). Avoid running the fuel tank below 1/4 capacity to prevent sediment intake. If the engine shows symptoms like rough idle, black smoke, or increased fuel consumption, have the injectors tested immediately. Proper maintenance can extend injector life beyond 200,000 km.
