FAQ

Q1: How do I verify that this injector (0445116059) will fit my engine?
A: You can verify compatibility by checking your engine’s current injector part number. If it matches any of the numbers listed (0445116059, 0445116019, 504385557, 50434148), it is a direct fit. Alternatively, provide us with your engine model or engine code, and we can confirm suitability for your specific application.

Q2: What is the difference between a new and a remanufactured injector?
A: A remanufactured injector is a used core that has been fully rebuilt to meet original specifications. This process involves replacing all wear parts, such as nozzles and internal seals, and testing the unit to ensure it performs like new. It offers a significant cost saving compared to a brand-new OEM injector while maintaining high reliability.

Q3: What are the common symptoms of a failing fuel injector?
A: Common signs include rough idling, poor fuel economy, black smoke from the exhaust, engine misfires, or a noticeable loss of power. Replacing faulty injectors promptly is crucial to prevent damage to other engine components, such as the turbocharger or DPF system. Professional installation and calibration are recommended.
