An engine "core" is your old, worn-out, or failed engine that you return to us after receiving your remanufactured replacement. This core becomes the foundation for our next remanufactured engine, allowing us to continue our sustainable manufacturing process.
The core charge (also called a core deposit) is a refundable amount added to your engine purchase price. This deposit ensures we receive your old engine back. When you return your core in acceptable, rebuildable condition, we refund this deposit in full.
Note: Many of our engines require no upfront core charge. Contact us for specific core requirements for your engine model.
Follow these five simple steps to return your core and receive your deposit refund
Call our team at 631-991-7700 or email to initiate your core return. We'll provide you with a Return Merchandise Authorization (RMA) number and shipping instructions.
Drain all fluids from the engine. Clean the exterior and ensure all components are intact. Document any damage with photos before shipping.
Use the original shipping crate or a sturdy pallet. Secure the engine to prevent movement during transit. Include your RMA number on the outside of the package.
Ship the core using a freight carrier. We recommend using the same carrier that delivered your remanufactured engine. Keep your tracking number for reference.
Once received, our team will inspect the core within 5-7 business days. Upon approval, your core credit will be processed to your original payment method.
To qualify for a full core credit, your engine must meet certain rebuildable condition standards
Cores with minor damage or missing non-essential components may still qualify for partial credit. Our team will evaluate each core individually and provide a fair assessment. Contact us before shipping if you're unsure about your core's condition.
Proper preparation ensures safe shipping and faster processing of your core credit
Remove all oil, coolant, and other fluids from the engine. Shipping companies may refuse engines with fluids, and leaks can cause damage during transit.
Take photos of your core before shipping. This protects you if any damage occurs during transit and helps expedite the inspection process.
Use the original shipping crate if available, or secure the engine to a sturdy pallet. Ensure the engine cannot shift during transport. Wrap exposed openings to prevent debris entry.
Write your RMA number clearly on the outside of the package. Include a copy of your invoice or order number inside the crate for easy identification.
