Used Buick Engines You Can Trust

When your Buick engine fails, replacing the entire vehicle isn’t the most cost-effective choice. A quality used Buick engine delivers reliable performance at a fraction of the cost of a new engine. Unlike junkyard parts, our used engines are inspected, compression-tested, and certified for durability.

Whether you drive a Buick Encore, Enclave, Regal, LaCrosse, Verano, or Century, a used engine lets you restore performance and extend the life of your vehicle without breaking the bank.

What Makes a Used Buick Engine Different?

A properly sourced used Buick engine is not a gamble. Each engine is carefully inspected, cleaned, and tested to ensure it meets quality and reliability standards.

Key components checked or refurbished include:

  • Pistons & rings
  • Crankshaft
  • Camshaft
  • Cylinder heads
  • Bearings
  • Gaskets & seals
  • Timing components
  • Oil pump
  • Valvetrain components

Every unit undergoes compression and leak testing to ensure it functions correctly before shipping.

Warranty & Certification You Can Rely On

Our used Buick engines are backed by warranty coverage ranging from 30 days to 6 months, depending on model and usage. Both personal vehicles and commercial fleets are supported.

Certifications and inspections may include:

  • Compression and leak testing
  • Verified mileage documentation
  • OEM component verification

You’ll receive documentation confirming the engine’s testing and warranty coverage.

Fitment for All Buick Models

We provide used engines for most Buick vehicles manufactured from 2005–2024, including:

  • Buick Encore
  • Buick Enclave
  • Buick Regal
  • Buick LaCrosse
  • Buick Verano
  • Buick Century
  • Buick Lucerne
  • Buick Park Avenue
  • Buick Cascada

Providing your VIN ensures an accurate engine match.

Cost Benefits

A used Buick engine typically costs 40–60% less than a brand-new OEM engine. Labor and installation costs are reduced due to correct fitment.

Average pricing by model:

  • Buick Encore 1.4L: $1,800–$2,500
  • Buick Regal 2.0L: $2,200–$3,000
  • Buick Enclave 3.6L: $3,000–$4,500
  • Buick LaCrosse 3.0L: $2,700–$3,800
  • Buick Verano 2.4L: $2,400–$3,200

Choosing a used engine saves long-term costs and avoids the need for vehicle replacement.

Shipping & Installation Support

All engines are shipped securely, palletized, and freight-ready. Liftgate service is available for residential or commercial deliveries. Typical delivery time is 3–7 business days, depending on your location.

We can recommend authorized installers and mechanics in your area, and instructions for warranty validation with your installer are provided with every engine.

Blockquote Section

"A used Buick engine is a smart investment. It restores your vehicle’s performance reliably without the cost of a brand-new engine."

When Should You Replace Your Buick Engine?

Common reasons include:

  • Engine knocking or rod failure
  • Oil contamination or sludge buildup
  • Overheating & head gasket failure
  • Excessive oil burning or smoke
  • Timing chain or belt failure
  • Loss of compression
  • Bearing wear
  • Complete engine shutdown

Replacing the engine is often cheaper than repeated repairs, and a quality used engine ensures peace of mind.

Eco-Friendly & Sustainable

Choosing a used engine reduces manufacturing emissions and metal waste. By reusing engines, you extend vehicle life and minimize environmental impact.
