RETURNING USED CORES
Most remanufactured parts require a core charge. If you are puchasing an item from Cardinal Parts that does require a core charge, you will be eligible for core credit upon return of your old core unit.  Please note that used cores must be returned within 30 days, provided the replacement parts were purchased at Cardinal Parts. All cores must be shipped back in the box you received your new/reman product in. If your original box arrives damaged, please contact us for further instructions at Support@CardinalParts.com.

Before returning your core, be sure to drain fluids from the core and place it in a plastic bag to prevent leakage. Then pack it in the box that contained the new/reman part you purchased from Cardinal Parts.

Cores that are incomplete, missing components, are burnt or tampered with, are damaged or have damaged components, or are disassembled, will not be accepted.

Customers are responsible for making sure cores are returned within the mentioned timeframe, and return shipping costs. If you have any questions or concerns, please contact us at 888-314-7222
