Modern vehicles are designed to withstand a great deal of wear and tear. They’re more fuel efficient than ever before, and able to milk every drop of gasoline for the most “bang” possible. The average lifespan of a car engine these days is far in surplus of 100,000 miles (many make it to the 200,000-mile mark, in fact). With that being said, any number of things can kill an engine early, and its not only because it was once a used engine for sale.
Maybe you were involved in a serious auto accident, or maybe the engine block had casting errors. Perhaps you threw a rod, or maybe you’re swapping out for something with a bit more power. In all these cases, you’ll want a new engine, but what you’re really getting is a remanufactured engine.
Why Isn’t It New?
Whether you’re doing a new engine install yourself and ordering the engine from your local parts store, going through a dealership, or working with a private repair shop, you should understand that you’re not getting a “new” engine. It’s new to you, certainly, but it’s not brand new, as in never taken out of the crate before. Ford or Chevy isn’t sending you an engine straight from their assembly line. You’re getting a remanufactured engine. What does that mean and why should you care?
The Realities of a Remanufactured Engine
First, let’s take a look at what a remanufactured engine really is. It’s not a rebuilt engine. It’s not “refurbished” and it’s not used. It’s remanufactured – that implies a complete re-engineering of the engine from the ground up. In fact, it’s new in all the ways that count.
In the world of remanufacturing, only certain components are reused, and then only after being completely inspected, ground down, sanded and refinished to the identical measurements and clearances it had when it rolled off the assembly line originally. These are the exterior and housing components – all the internals are replaced with new components.
All remanufacturing takes place in a factory environment, using computer-guided tools. Don’t confuse it with rebuilding, which can take place at your local mechanic shop on the workbench. Remanufacturing is an intensive process that results in an engine that’s as close to “new” as you’ll ever get.
Rebuilt or Remanufactured?
You might think that going the rebuilt route is the better option here, now that you understand a “new” engine isn’t really new. However, there’s a lot to be gained by going with a remanufactured engine as opposed to a rebuilt one.
Lifespan – One of the most important considerations here is lifespan. When you opt for a remanufactured engine, you’re getting the same lifespan as an engine installed in a vehicle coming straight from the assembly plant. A rebuilt engine, on the other hand, might have only a few more miles left in it.
Reliability – Remanufactured engines are hands down more reliable than rebuilt engines. That’s because they’re completely re-engineered, rather than just having failed parts replaced.
In the end, a remanufactured engine is the ideal solution – it’s as close as you’ll get to “new”.
