From New to Refurbished and Everything In Between

Posted by Mark Houlahan on

Your diesel engine has started to stall and misfire. You notice you aren’t getting the miles per gallon you used to. The exhaust from your engine smells worse than ever, but even over that, you can smell a fuel odor emanating from your vehicle. If these are happening to you, your fuel injector probably needs to be replaced.

When it’s time to replace a fuel injector (which happens about every 100,000 miles on a diesel engine) or any of the diesel fuel injection parts, it can be tempting to save a few dollars and get parts labeled rebuilt, remanufactured, or refurbished. But what do these terms mean for you and your vehicle? Let’s dive into the definitions of each different level of parts you may find as you shop.

Original Engine Manufacturer (OEM) Diesel Products

The original engine manufacturer is the manufacturer that produced the original vehicle and its parts. If a product is made by the same manufacturer as the car, it guarantees compatibility between the vehicle and the replacement part (as opposed to aftermarket products, where the new part is not guaranteed to be compatible with your vehicle because it was made by a different company).

Because these products are guaranteed to work with your vehicle, they are often more expensive than other options. OEM products can be purchased through the automaker directly or through branded car dealerships.

There are two types of OEM products that you can find on the market: OEM new and OEM remanufactured.

  • OEM New If an OEM product is listed as OEM new, it is built by the original manufacturer and each part of the product is new and not previously used. It is up to the OEM standards for the original product and will have a long lifespan as none of the parts have any wear and tear on them.
  • OEM Remanufactured A product that is OEM remanufactured has been disassembled and inspected, then reassembled using new parts where necessary. The updated components may include nozzles, solenoids, plungers, seals, valves, or anything else that will no longer function properly. An OEM remanufactured product will be of higher quality than another rebuilt or refurbished product because it must meet the standards from the original manufacturer for your specific vehicle.

Remanufactured or Rebuilt Diesel Products

A part that has been remanufactured or rebuilt is a used part that has been taken apart, inspected for wear, and then rebuilt using new components where they are needed. It is then tested to ensure the parts work together smoothly.

Refurbished Diesel Products

A refurbished part is typically the least expensive option for a replacement part. Refurbished parts are used parts that have been removed, cleaned externally as well as internally, and then tested to ensure it still runs. No parts are replaced. As long as it still runs, it is sold as a refurbished product.

New Diesel Products

While saving some money on refurbished or remanufactured parts might make sense for some situations, for others it is worth the investment to buy a new product to replace in your vehicle.

Buying new can bring peace of mind that the pieces are all the best quality, never used, and do not have any hidden wear that couldn’t be addressed when it was remanufactured or refurbished. It also ensures that all the replacement parts within the part are from a quality, established brand. You also know that the life of your part will be long since none of the pieces will have been previously used.

Mislabeled Products

It is not unheard of in the auto parts industry for deceptive labeling to occur. Deceptive labeling would be calling a part remanufactured even if it was not rebuilt with new parts, only cleaned.

As you search for parts it is important to not only do your research on the part you need but to also do your homework on the diesel parts supplier that is trying to sell it to you. Reading reviews can help you get a better picture of the quality the company provides and if they back up their work.
