Important Reman FAQs (select your role)

Q: Why do people buy remanufactured engines?

A: People choose remanufactured engines to save money, get a high-quality replacement that performs like new, benefit from warranty protection, and make an environmentally responsible choice. A rigorously remanufactured engine restores worn components and delivers reliable, long-lasting performance at a fraction of the cost of a new engine.

Q: What are the key benefits of a remanufactured engine?

1. Cost-Effective Savings

Remanufactured engines offer significant cost savings compared to buying new. You get comparable performance and reliability at a much lower initial investment.

2. High Quality & Reliability

During the remanufacturing process, every engine is fully disassembled, precision-cleaned, inspected, and rebuilt. All worn components are replaced, and the final build meets or exceeds OEM specifications—ensuring dependable performance.

3. Environmentally Friendly Choice

Remanufacturing reuses major engine components, reducing waste and minimizing the need for new raw materials. It’s a sustainable, eco-conscious option for engine replacement.

Q: Do remanufactured engines come with a warranty?

A: Yes. Reputable remanufactured engines typically include warranties that cover a specific duration or mileage. This protection provides peace of mind and safeguards you against defects.

What you should expect from any engine provider

An engine purchase isn’t just about the upfront price—it’s also about how well you’re protected after installation. A strong warranty and support program reduces your risk, protects your investment, and keeps your vehicle or equipment working as expected.
Use the following information to evaluate any vendor’s warranty and support program and to understand the actions that protect (or jeopardize) your coverage.

Warranty basics you should expect from any provider.

When you review warranty information from any engine vendor, look for clear, written answers to questions like:

  • What is covered?
    • Parts only, or parts and labor?
    • Coverage for long blocks vs. complete drop-in engines.
  • How long is the coverage?
    • Time (e.g., 12, 24, 36 months) and/or mileage/hours (e.g., 100,000 miles, 3,000 hours).
  • Where can repairs be done?
    • Any reputable repair shop, or only specific facilities?
  • What is not covered?
    • Normal wear-and-tear items, misuse, lack of maintenance, or pre-existing vehicle issues.
  • How is labor paid?
    • Standard labor-rate, capped hourly rate, and any stated warranty labor rates, reimbursement and reasonable repair times.
  • What is the claim process?
    • Who to call, what information you need, and what approvals are required before work begins.

If these details are unclear or hard to get in writing, that’s a signal to ask more questions before you commit.

Actions that can protect—or jeopardize—your warranty

Most engine warranties require you to follow certain steps. Skipping them can delay or even void your coverage, regardless of the provider. Below are common expectations you’ll see in warranty terms.

  • At delivery: inspection before signing
  • Inspect the shipment before signing the delivery receipt.
    • Look for visible damage to the packaging or engine.
    • Take photos and note any damage on the freight carrier’s paperwork before signing.
  • Why it matters:
    • Freight damage is often handled differently than manufacturing defects.
    • If damage isn’t documented at delivery, the freight carrier or vendor may not cover it under warranty.
  • At installation: follow provider instructions
  • Use the installation instructions provided by the engine manufacturer or remanufacturer.
    • Follow torque specs, priming procedures, and any required flush/cleaning steps.
    • Replace required components (e.g., filters, hoses, coolers) as instructed.
  • Why it matters:
    • Improper installation is a leading cause of failures that are not covered by warranty.
    • Skipping required steps may be considered misuse or neglect.
  • During operation: proper fluids and use
  • Use approved fluids, filters, and parts.
    • Follow the recommended oil type, coolant, and service intervals.
  • Operate within normal parameters.
    • Avoid overloading, severe overheating, or operating outside recommended limits.
  • Why it matters:
    • Using incorrect fluids or severely abusing the engine can be classified as misuse and may void coverage.
  • Ongoing: maintenance and records
  • Perform regular maintenance per the recommended schedule.
  • Keep documentation.
    • Save invoices and service records showing oil changes, filter replacements, and major repairs.
  • Why it matters:
    • In the event of a claim, vendors often request maintenance history.
    • Good records help demonstrate that you’ve taken proper care of the engine.

Common issues that can limit or void warranty coverage

While every provider’s terms are different, many warranties limit or exclude coverage when:

  • Freight damage is not documented at time of delivery.
  • The engine is installed or repaired by someone who does not follow the provider’s instructions.
  • Required components (e.g., oil cooler, injectors, filtration) are not replaced or serviced as specified.
  • The engine is modified (emissions-deleted) or “tuned” beyond OEM specifications.
  • Maintenance schedules are ignored, or there is no documentation to support proper maintenance.
  • Failures are caused by other vehicle or equipment systems (cooling, fuel, electrical) that were not repaired.

The goal of these terms isn’t to deny coverage—it’s to ensure the engine is installed, used, and maintained in a way that supports long, reliable life.

What strong after-sale support looks like

Beyond the written warranty, a reputable provider should offer:

  • Technical support:
    • Access to knowledgeable technicians to help with installation questions and troubleshooting.
  • Clear claim handling:
    • A defined process for opening a claim, getting authorization, and understanding what’s covered.
  • Flexible repair options:
    • The ability to work with any local, reputable repair facility to minimize downtime, rather than limiting you to OEM-certified dealerships only.
  • Parts support and documentation:
    • Build records or component information to quickly identify the right replacement parts if needed.

When evaluating engine options, consider both the warranty terms and the quality of support behind them. Together, they significantly reduce your risk and maximize the long-term value of your engine investment.
