What is a “core” or a “core charge"?

A core is a term used in the automotive industry for the old defective engine in your vehicle. A core charge is a deposit left with us to ensure the core engine is returned. We pay the return shipping on the core engine. All core charges are refunded as soon as the old defective engine arrives at our location. This normally takes 2 – 3 business days.
