    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.

    PLEASE READ AND UNDERSTAND: Engine warranties are limited to manufacturing defects in the block, heads, pistons, crankshafts, camshafts, rockers, and oil pumps. All other parts that may be provided are “Accessories and Extra Parts.” No warranty is provided for any such parts that are attached, including parts such as switches, sensors, cables, injectors, electronics, belts (including timing belt/chain), hoses, water pumps, manifolds and oil pans.

    Installation Check List: (Failure to complete the following will void Warranty)

    • Determine why the original engine failure occurred and make appropriate repairs.
    • Insure this engine is the same application as the one being replaced.
    • Clear all computer diagnostic codes from the vehicle prior to installing.
    • Exchange the oil pan and pick up tube.

    • Replace engine oil, oil filter, air filter, fuel filters, coolant-antifreeze.
    • Drain excess oil and coolant from exhaust system.
    • If equipped with an engine oil cooler the radiator or external cooler must be replaced.
