About this part
0445120361 is supplied as a remanufactured replacement common rail injector. Cross-reference numbers: 0445120361, 5801479314. Application recorded for this part: Fits IVECO — 445 120 361.
The injector sits at the end of the rail and does the final metering work: it receives fuel already at high pressure and decides both how much enters the cylinder and how well atomised it is. That combination governs power, smoke and fuel consumption more directly than almost any other part on the engine.
Typical signs are poor starting hot or cold depending on whether the unit is weeping or sticking, an idle that hunts or sounds uneven, smoke under acceleration, and sometimes a smell of diesel in the oil where an injector is leaking internally.
Before replacing anything, distinguish injector faults from their look-alikes. Comparing return volume between cylinders and running a cut-out test on a diagnostic tool will show which cylinder is actually contributing — cheap checks that prevent replacing parts that were not faulty.
Installation notes: new copper washers and seals are mandatory, the seat must be clean and undamaged, and the retainers should be torqued to the engine manufacturer's specification. If the ECU stores injector codes for this engine, program them after fitting, otherwise the engine will not compensate correctly.
Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
