Refund policy
We want you to be confident in every purchase from CoreDieselParts.com. If something is not right, here is exactly how returns and refunds work.
30-Day Returns
You may return most new, unused, uninstalled parts in their original packaging within 30 days of delivery for a refund of the product price. To start a return, email sales@coredieselparts.com with your order number and the reason for the return, and we will send you return instructions and a Return Merchandise Authorization (RMA).
Condition of Returned Items
- Parts must be new, unused, and uninstalled, in the original manufacturer packaging.
- Parts that have been installed, disassembled, or damaged after delivery are not returnable.
- Electrical parts (sensors, modules, glow plugs, injectors) are not returnable once installed, for safety and warranty reasons.
Refunds
Once we receive and inspect your return, we will approve the refund and issue it to your original payment method within 3–5 business days. Your bank may take additional time to post the credit. Original shipping charges are non-refundable, and the customer is responsible for return shipping unless the return is due to our error or a defective part.
Core Charges
We sell new replacement parts. We do not charge core fees and do not require you to return an old ("core") part. The price you see is the full price of the item.
Damaged, Defective, or Wrong Items
If your order arrives damaged, defective, or incorrect, email us at sales@coredieselparts.com within 7 days of delivery with photos and your order number. We will make it right at no cost to you — a replacement or a full refund including shipping.
Cancellations
Need to cancel? Contact us as soon as possible. If your order has not yet shipped we will cancel it for a full refund. If it has already shipped, our standard return process applies.
