A used engine is pulled directly from a donor vehicle and tested for functionality. A remanufactured engine has been completely disassembled, inspected, all worn parts replaced with new or re-machined components, and then reassembled to meet or exceed OEM specifications. Think of it as a complete factory refresh.

At AutoPartMax.com, all our used engines undergo rigorous testing, including compression tests, leak-down tests (where applicable), and visual inspections for damage or excessive wear. We also provide details on mileage and vehicle history when available, ensuring transparency.

Yes, absolutely! All our used engines come with a standard warranty, and our remanufactured engines typically offer an even more comprehensive warranty due to their extensive rebuilding process. Specific warranty details will be provided for each engine.

Engine compatibility is determined by several factors, including the make, model, year, VIN (Vehicle Identification Number), and engine code of your vehicle. Our system and experts will guide you to ensure the engine you purchase is a perfect fit for your specific car or truck.

Generally, our engines are sold as 'long block' or 'short block' assemblies, meaning they include the core components like the block, crankshaft, pistons, and cylinder heads. External accessories (alternator, starter, AC compressor, etc.) are typically not included and should be swapped from your original engine, unless otherwise specified.

Shipping times vary depending on your location and the engine's current warehouse. We work with trusted carriers to ensure prompt and secure delivery. Estimated delivery times will be provided at the time of purchase, and tracking information will be shared once your engine ships.

In the rare event of an issue, please contact our customer support team immediately. We stand by our products and our warranty covers eligible concerns. Our goal is to ensure your complete satisfaction.
