High-performance engines: because of what these engines are built to do, high-performance engines (for example, our HEMI Strokers) come with no warranty. That said, we work with customers case by case, and if something is wrong we will generally try to make it right.

What's covered (both plans)

  • Engine block, cylinder heads, crankshaft, camshaft(s), connecting rods, pistons, valves, valve springs, timing components, oil pump, and all internally lubricated parts.
  • Machining and assembly done by Phoenix Engine Specialists.
  • 3-Year Extended only: labor to remove and reinstall the covered engine at $50/hour, at our shop or an approved facility.

On the standard 1-year warranty, labor to remove and reinstall the engine is not covered.

What's not covered (both plans)

  • Damage caused by overheating, detonation, pre-ignition, or lack of lubrication.
  • Damage from improper installation, unqualified mechanic work, or not following the break-in procedure.
  • External components, including but not limited to electrical, cooling, fuel and exhaust systems, transmission, clutch, or drivetrain.
  • Engines used for racing, heavy towing (over the manufacturer's GVWR), off-road competition, or commercial fleet use.
  • Consequential or incidental costs such as towing, rental vehicles, lodging, lost wages, or downtime.
  • Normal wear items such as gaskets, seals, filters, spark plugs, belts, hoses, or fluids, unless the failure was directly caused by a covered part.

How to make a warranty claim

  1. Diagnosis: a licensed/certified mechanic must diagnose the problem and send the diagnosis to us. A verbal opinion or a "feeling" that something is wrong is not enough.
  2. Tell us right away: contact us as soon as you notice a possible problem. Continuing to drive after a failure may void the warranty.
  3. Documents: your original receipt/invoice from us, all maintenance records (oil changes, filters, coolant flushes), receipts for any repairs during the warranty period, and proof of proper installation if we didn't install it.
  4. Inspection: the engine must come back to us for inspection. The customer pays shipping unless the claim is approved.
  5. Approval: repairs only go ahead after inspection and approval. Unauthorized repairs void the warranty.

Labor rate (3-Year Extended only)

We pay a flat $50/hour for approved warranty repairs. This rate is not negotiable. If a shop won't accept $50/hour, the claim is denied and the customer pays 100% of that shop's bill. Shops that want to become an approved warranty station can call (623) 204-6365.

Break-in procedure (required to keep your warranty)

First 1,000 miles: - Change the oil and filter at 1,000 miles, using the manufacturer's recommended viscosity and type. - Vary engine speed often between 2,000 and 4,000 RPM. Avoid long idling or constant RPM, like highway cruising. - No heavy loads, towing, or high-RPM driving. - Check and top off the oil often. Some oil use is normal during break-in. - Metal particles in the oil at the first change are normal and are not a defect.

After 1,000 miles: drive normally, but avoid sustained high RPM or heavy loads until 3,000 miles when you can.

Not following the break-in procedure voids the warranty.

Required maintenance (keep your receipts)

  • Oil and filter change every 3,000 miles or 3 months, whichever comes first, using API-rated oil of the correct viscosity.
  • Coolant flush and replacement every 2 years or 30,000 miles.
  • Regular checks of belts, hoses, and cooling system parts.
  • Good-quality fuel. Avoid contaminated or low-octane gas.

Receipts must show the date, mileage, and services performed.

General terms

  • The warranty can't be transferred and only covers the original purchaser.
  • We will repair, replace, or refund any covered part, at our discretion.
  • If replacement isn't possible, any refund is prorated based on mileage and time.
  • This warranty gives you specific legal rights. You may also have other rights, which vary by state.

Returns & refunds

Return window - Regular engines can be returned within 30 days. The 30 days start on your delivery date, or the date your job is completed. - To be returned, the engine must be unused and in its original packaging. A 20% restocking fee applies to cancellations and returns within the 30 days. - After 30 days, engines can't be returned or refunded.

Installed engines - We don't accept returns or give refunds on engines that have been installed. After that point, the warranty is your only option.

Custom and high-performance engines (including our HEMI Strokers) - Custom and high-performance engines, and deposits on custom orders, are fully refundable if cancelled within 24 hours of ordering. - After 24 hours, they are non-refundable.

Deposits - Custom orders: fully refundable if cancelled within 24 hours of ordering, and non-refundable after that. - Regular orders: refundable within 24 hours.

Performance add-ons (cams, lifters, studs, etc.) - Refundable if cancelled before your build starts. Once the build has started, add-ons are non-refundable.

Extended warranty - The $1,500 3-Year Extended Warranty is refundable up to 1 year after purchase, or before your standard warranty runs out.

Return shipping - The buyer pays return shipping and is responsible for securing the engine for transit. - If the engine was damaged in shipping, the carrier or Phoenix Engine Specialists covers it. Inspect your delivery before signing, and tell us right away about any damage.

Processing - Allow 3-5 business days for processing after a returned engine arrives.
