Core Policy
Effective 2/29/2024

What is a core?

A core is an old unit or part that is replaced with a new or remanufactured part. Many of our remanufactured parts have a core charge billed at sale, and require the return of the old part to receive credit. The core must be in acceptable condition to receive core credit.

Why was I charged a core price, and how can I get that refunded?

The core price is the dollar value of the core charge, and requires the return of the core part to receive credit. Cores are eligible for return up to 30 days after sale, and must be in acceptable condition to receive full credit. Returned cores must include original sale information, e.g. Order Number or Invoice Number, to receive credit.

How do I return a core for credit?

To return your core for credit, drain your core of all fuel and fluids and package it in the box the replacement part shipped in. Take care to ensure the part does not leak fuel or fluids, as many carriers will decline to ship packages with stained packaging or with visible leaks. Include the original sales information to identify your sales order. Sales information includes either the Sales Order Number, or Sales Invoice Number. Alternatively, you can include copies of the sales paperwork included with the replacement part in shipment. Cores are eligible for return up to 30 days after sale, and after 30 days will no longer receive credit even if returned. Cores should be returned to: The branch that you originally purchased the product from (unless instructed in writing to send to a different location). Cores may also be returned in person to the Midwest Diesel Parts Location of purchase.

What is an acceptable condition for a core?

We expect the cores we receive to not work properly, but all cores must be in rebuildable condition without missing parts to receive credit. Some parts have additional requirements, but generally the following conditions apply to all cores: All cores must be like for like and exactly match the replacement parts. No credit will be issued for mismatched cores. No credit will be issued for cores that have been in a fire, disassembled, severely damaged or broken, or subjected to fuel contamination (water, biodiesel, waste vegetable oil, etc.). Partial core credit may be issued for cores with missing parts and pieces that were included in or on the replacement part, including valves, tubes, electronics, cap nuts, and other components. No or partial credit will be issued for cores that have damaged electrical components or connectors, regardless if this damage occurred in transit.

Turbocharger core acceptable condition?

Turbocharger cores are graded depending on the condition of the core upon receipt according to the remanufacturer specifications and if a turbo core is damaged, disassembled, or incomplete you will not receive full credit.
