    1. Contact our customer service: Reach out to our customer service team via phone, email, or online form to initiate the process. They will provide you with detailed instructions and address any questions or concerns you may have.

    2. Prepare the cylinder head and engine core: Clean the cylinder head and engine core thoroughly, removing any excess oil, dirt, or debris. Ensure all parts are properly packaged and protected to prevent damage during transit. Avoid using packing peanuts, as they can be messy and potentially harmful to the environment.

    3. Document and label: Take clear photographs of the cylinder head and engine core from various angles before packaging them. This documentation will serve as a reference for both you and our team. Label each package clearly with your name, contact information, and any unique identifiers provided by our customer service team.

    4. Secure packaging: Place the cylinder head and engine core in separate sturdy boxes or containers. Use appropriate packing materials such as foam, bubble wrap, or other protective cushioning. Ensure the packaging is secure and well-sealed.

    5. Arrange shipping: If you're sending complete engines, we can help arrange freight shipping with liftgate services for your convenience. Contact our customer service team to discuss the details and provide them with the necessary information. They will assist you in scheduling the freight shipment.

    6. Share tracking information: Inform our customer service team about the shipping carrier, tracking number, and expected delivery date. This allows us to anticipate the arrival of your cylinder head and engine core and streamline the processing time.

    7. Await confirmation: Once your shipment arrives at our facility, our team will inspect and confirm the condition of the cylinder head and engine core. We will notify you of their arrival and provide updates throughout the evaluation and servicing process.

    Remember to follow any specific instructions provided by our customer service team and communicate any specific shipping requirements or preferences. We're here to assist you throughout the process and ensure a smooth and efficient experience.
