21569191 is supplied as a remanufactured replacement injector. Cross-reference numbers: 21569191, 21207143, 7421207143, 21582103. Application recorded for this part: Fits Volvo. 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. Symptoms that point to injector wear include hard starting when hot, rough idle, white smoke at start-up or black smoke under load, a sharp knocking from one cylinder, increased fuel consumption and a gradual loss of power. Do a return-flow check before buying anything. Comparing leak-off volumes between cylinders takes minutes, and if one injector returns far more than its neighbours, that single test has answered the question. Fitting notes: replace as a set rather than singly. A lone new injector will deliver differently from the worn ones around it, which usually reproduces the rough running. Use new sealing washers every time, clean the injector bore and seat carefully, and check whether your engine management expects classification codes to be entered after installation. Rebuilt rather than refurbished: full teardown and measurement, worn components replaced instead of cleaned and reused, sealing surfaces restored to specification, then bench calibration and testing. The record is what separates this from a used part — we can provide the test sheet for your order. Covered by a 12-month warranty.
