Every engine, transmission, and part we sell is tested before shipping and backed by a written warranty for your peace of mind.
At Prime Used Engines, every used engine, transmission, and auto part that leaves our Drumheller facility has already passed a hands-on inspection process before it is ever listed for sale. Engines are compression tested, transmissions are checked for proper fluid condition and shift function, and accessory components are bench tested where applicable. We stand behind that testing process with a written warranty on every part we sell, because we believe customers who order sight-unseen deserve a documented guarantee of quality, not just a verbal assurance.
This Warranty Policy explains what is covered, what is excluded, how long coverage lasts by part category, and the exact steps to file a claim if a covered part fails during the warranty period. This policy applies to all purchases made through Prime Used Engines by phone, email, or through a sales representative, and it supplements — but does not replace — our separate Return & Refund Policy, which governs buyer's-remorse returns and shipping errors.
Coverage periods begin on the date of delivery to the shipping address provided at checkout. The table below summarizes standard warranty terms by part category. These are Prime Used Engines' own store policy terms and are provided for informational purposes as part of our sales terms, not as a manufacturer's guarantee.
| Part Category | Standard Warranty Period | What's Covered |
|---|---|---|
| Used Engines | 90-Day Limited Warranty | Internal mechanical failure of the core engine assembly under normal operating use |
| Used Transmissions | 90-Day Limited Warranty | Internal mechanical failure of the core transmission assembly under normal operating use |
| Engine & Drivetrain Accessories (alternators, starters, turbochargers) | 30-Day Limited Warranty | Defects in function that cause the component to fail to perform its intended purpose |
| General Auto Parts (radiators, AC compressors, suspension parts) | 30-Day Limited Warranty | Defects in function that cause the component to fail to perform its intended purpose |
Our warranty covers defects in material or workmanship that are discovered during normal use of the part within the applicable warranty period listed above. This includes:
To qualify for coverage, the failure must be verified by our team, which may include a review of installer notes, diagnostic codes, or a written mechanic's report describing the nature of the failure.
The following situations and conditions are excluded from warranty coverage:
If you believe a part you purchased has failed within the applicable warranty period, please follow these steps:
Many used engines and transmissions are sold with a "core" value built into the transaction. If a warranty claim is approved on an engine or transmission, we may require the original defective unit to be returned to us as the core before a replacement is shipped or a refund is issued. Core returns must generally be shipped back within 15 days of claim approval, using shipping instructions and any applicable shipping label provided by our team. Cores that are not returned within the required timeframe, or that are returned missing major components, may result in a reduced refund or an additional core charge.
This warranty covers the part itself — it does not cover labor, towing, rental car expense, diagnostic fees charged by a third-party shop, or any other incidental cost associated with removing a failed part or installing a replacement, unless those costs have been separately agreed to in writing by Prime Used Engines management prior to the work being performed. We strongly recommend having any engine or transmission installed by a qualified professional and retaining all installation invoices and diagnostic paperwork, as this documentation may be required to support a warranty claim.
Our warranty support team is available during regular business hours to assist with claims, answer coverage questions, or help you gather the documentation needed for a claim review.
