FAQ

Q1: Is this injector a direct replacement for my Dodge Ram 5.9L Cummins?
A: Yes, part number 0445120238 is a direct OEM replacement for the 5263316 injector used in Dodge Ram 2500/3500 with 5.9L Cummins common rail engines (2003-2007). However, please verify your engine’s injector part number by checking the existing injector or consulting your vehicle’s service manual. This injector is not compatible with 12-valve or 24-valve mechanical injection systems.

Q2: What installation precautions should I take?
A: Installation requires professional knowledge of common rail systems. Always replace injector seals and copper washers (not included). Clean the injector bore thoroughly before installation. Torque the injector retaining clamp to manufacturer specifications (typically 20-25 Nm). After installation, prime the fuel system and check for leaks. We recommend having a diesel specialist perform the replacement to avoid engine damage.

Q3: How do I maintain these injectors for long service life?
A: Use high-quality diesel fuel with proper cetane rating and ensure your fuel filter is replaced regularly (every 10,000-15,000 miles). Contaminated fuel is the primary cause of injector failure. If you experience rough idling, poor fuel economy, or black smoke, have the injectors tested professionally. Our injectors come with a 6-month warranty, but proper maintenance can extend their lifespan significantly beyond that period.
