Accepted Answer

Question 5

How long does a remanufactured Cummins ISB engine last?

Accepted Answer

A remanufactured Cummins ISB engine typically lasts 200,000 to 500,000+ miles with proper maintenance — comparable to a brand new engine. The longevity of your remanufactured Cummins ISB 5.9L depends on regular oil changes, proper cooling system maintenance, using the correct fuel and fluids, and following the manufacturer's recommended service intervals. Our remanufactured long blocks are built to OEM specifications using all-new internal components, which is why they deliver the same service life as a factory-new engine.

Question 6

Is a remanufactured Cummins ISB better than a used or rebuilt engine?

Accepted Answer

Yes, a remanufactured Cummins ISB is significantly better than a used or rebuilt engine because every component is replaced or restored to OEM specifications. A used engine has unknown history and remaining life. A rebuilt engine only replaces worn-out parts. Our remanufactured Cummins ISB 5.9L engines are completely disassembled down to the bare block, every component is cleaned and inspected, and all wear items are replaced with new parts — including pistons, bearings, gaskets, seals, timing components, and the oil pump. The engine block and crankshaft are precision machined to factory tolerances, delivering better reliability, longer life, and a stronger warranty than used or rebuilt alternatives.

Accepted Answer

Yes, our remanufactured Cummins ISB long block engines are built to be a direct, bolt-in replacement for the original engine in your 2001 Freightliner XC Straight Rail. We match the engine to your specific year, make, model, and configuration to ensure proper compatibility with your vehicle's emissions systems (EGR, DPF, SCR/DEF), engine management computer, wiring harness, and mounting points. When you call us at (631) 991-7700, our specialists will verify the exact engine configuration for your 2001 Freightliner XC Straight Rail using your VIN to ensure a perfect match.

We make the core return process easy and hassle-free. The core return program helps us keep remanufactured engine prices affordable by recycling engine blocks and other reusable components. Your old engine core should be complete and not have any cracked or damaged major castings.
