USED ENGINES

Buying a used engine can have several benefits, including:

1. Cost Savings: Used engines are typically significantly cheaper than new engines, with savings ranging from 30% to 60%.

2. Faster Availability: Used engines are often readily available,reducing downtime and getting your vehicle back on the road sooner.

3. Lower Depreciation: New engines depreciate rapidly in the first few years. Buying used reduces this initial depreciation hit. 

4. Wider Options: You may find a wider selection of used  engines from various sources, including salvage yards, online marketplaces, and repair shops.

5. Opportunity for Upgrade: You might find a used engine with upgrades or modifications that enhance performance or efficiency.

6. Environmentally Friendly: Reusing an engine reduces the demand for new engine production, which requires significant resources and energy.

Engines suffer from a myriad of sources; wear and tear can eventually destroy them. While a properly maintained engine can last hundreds of thousands of miles, a poorly maintained engine can and will fail.

In case of engine failure, the most cost-effective solution is to choose arefurbished engine. A rebuilt engine is one that has been completely disassembled and rebuilt from the ground up.

Do not confuse a rebuilt engine with a rebuilt engine. Remanufacturing is carefully done at the factory and involves disassembling the entire engine,
cleaning all components, and covering or replacing defective parts. Pistons are changed, cylinders are bored, and then everything is put together in a
precision computer before performance testing. At BUAP, we take great pride in providing service centers, mechanic shops and individual customers with the highest quality components at all times. This also applies to upgraded engines from GMC, Ford, Jeep and Chevy.

Remanufactured Engines – Quality, Price, and Excellence

WHY CONSIDER PURCHASING REMANUFACTURED ENGINES?

Buying a remanufactured engine is a smart decision for several reasons, each of which increases cost-effectiveness, reliability, environmental responsibility and performance:

  • Cost savings: Remanufactured engines are significantly cheaper than new engines. This price difference makes them a budget choice for those looking to extend the life of their vehicle without the financial burden of buying a new engine.
  • High Quality and Reliability: Upgraded engines go through a thorough rebuilding process where they are disassembled, cleaned, inspected and repaired according to original manufacturers. Worn or damaged parts are replaced with new or upgraded components, which can often include upgrades that correct original design flaws, increasing engine reliability andefficiency.
  • Warranty and Support: Like new engines, remanufactured engines often come with a warranty for added peace of mind. Depending on the manufacturer or remanufacturer, this warranty can rival or even exceed that of new engines.
  • Environmental benefits: Choosing a remanufactured engine is an environmentally friendly choice. The reproduction process uses fewer new materials and less energy than building a completely new engine, reducing waste and energy use. It also helps keep engines out of landfills, giving them a new lease of life.
  • Availability: Remanufactured engines are readily available in a variety of makes and models, which can be especially useful for older or discontinued vehicles that are no longer manufactured for new engines.
  • Fast Rework: Because reworked engines are built from existing engines,   they can often be produced and shipped faster than a new engine, which may have to be built from scratch.
  • Improved Performance: Because remanufactured engines are built to original specifications, they often come with upgrades and modifications that improve performance. This ensures that they run more efficiently and can even achieve better fuel economy than before.

For vehicle owners who need a reliable engine replacement solution without the high cost, or those looking to make an environmentally friendly choice, remanufactured engines offer an attractive option that balances quality, affordability and durability

WHAT IS THE DIFFERENCE BETWEEN A RE-MANUFACTURED ENGINE AND A REBUILT ENGINE?

A rebuilt engine is an engine that has been disassembled, cleaned, repaired and rebuilt to meet original manufacturer specifications. During
remanufacturing, any worn, damaged or damaged components are replaced with new or remanufactured parts and the engine is rigorously tested to ensure optimum performance. A rebuilt engine is essentially restored to original condition, offering the same performance, longevity and reliability as a brand new engine. A rebuilt engine, on the other hand, usually just replaces faulty or damaged engine components and reassembles it.

Rebuilt engines are not subject to the same rigorous testing and quality control processes as rebuilt engines and may be assembled from used or aftermarket parts instead of new OEM parts. While both rebuilt and rebuilt engines can offer a cost-effective solution compared to buying a brand new engine, there are some important differences. Remanufactured engines are generally of higher quality and more reliable than rebuilt engines. They also tend to have better warranties, which often give customers added peace of mind. Ultimately, the best choice depends on the specific needs and budget of the customer..
