FAQ

Q: Will this injector fit my Caterpillar 3516C engine?
A: Yes, this injector (359-5469) is a direct fit for the 3512C and 3516C engine models. However, we always recommend checking your engine’s serial number and the specific injector code stamped on your old part to ensure compatibility, as there can be variations within engine families.

Q: Is this a new or remanufactured part, and what is the installation procedure?
A: This is a professionally remanufactured unit. It is ready for installation. We highly recommend replacing the injector hold-down bolts and copper washers with new ones during installation to prevent leaks. The injector should be installed using proper torque specifications. For complex installations, please consult a certified Caterpillar service technician.

Q: What is the expected lifespan of this remanufactured injector?
A: The lifespan of a remanufactured injector depends heavily on fuel quality, maintenance schedules, and operating conditions. When installed correctly and used with clean, high-quality diesel fuel and proper fuel filtration, this injector can provide a service life comparable to a new OEM unit, typically thousands of hours. Regular maintenance of your fuel system is key to maximizing its life.
