Core Policy

*What is a Core?*

The core is the old unit that is to be replaced with the new or rebuilt item being purchased.

*Most commonly associated with a core charge are parts such as turbochargers, injectors, injection pumps, and high pressure oil pumps needing a replacement part.

*You must return the old core to receive a refund on the core charge. All cores must be exactly the same as the new product shipped and include all parts and pieces that were received on your new replacement product. They must also be returned in the proper manufacturer’s box.

*All cores must be in a condition capable of being rebuilt to receive a refund of the initial core charge (Any cores with fire/heat damage, water damage, or broken/unusable in any way will not be accepted.)

*Core Policy*

Any customer purchasing a product with a core will be charged in full for the core upon purchase of the new product subject to full or partial refund when the core is returned undamaged to South Central Diesel, Inc. (See timeline below)

*PayPal & All Other Credit Card Orders:*

All non-credit card orders, take PayPal for example, will require that we have a credit card number on file when orders with a core value are placed. The on file credit card will be charged and then refunded when we receive the proper core undamaged. If you do decide to complete your order with one of these methods a South Central Diesel, Inc. representative will be in contact with you to obtain a credit card strictly for this purpose. For any questions, please contact us toll-free at 1-(800)-228-8482.

*Core Physical Condition:*

Here are some examples as to why you would not receive any or just a partial payment on your core.

*If the core were to come back with any Fire/Heat Damage

*If we were to receive the core with any damage caused by Water
*If we were to receive the core broken/dismantled in ANY way
*If we receive the core disassembled/torn apart
*If the core we receive comes back not complete/missing any pieces

The refund amount is not determined by South Central Diesel, Inc., but by the manufacturer receiving the core. In the event you will not receive a full refund of your returned core, you will be contacted directly by South Central Diesel, Inc.
