    Frequently Asked Questions About International Truck Engine Parts

    What International engine models are your parts compatible with?

    Our International engine parts are designed to fit a wide range of models including the DT466, DT530, MaxxForce 7, MaxxForce DT, MaxxForce 9, MaxxForce 10, MaxxForce 13, and the newer A26 engines. Each product listing includes specific engine model compatibility in the description. We recommend checking your engine serial number against our fitment guide or contacting our support team at 1-888-875-7787 if you need help confirming compatibility for your specific truck year and model.

    Are these OEM International parts or aftermarket replacements?

    We carry both genuine OEM International parts and high-quality aftermarket alternatives. OEM parts are clearly labeled in our product titles and descriptions. Our aftermarket options meet or exceed OEM specifications and often come from trusted manufacturers like Dorman, PAI Industries, and Interstate McBee. Many customers choose aftermarket parts for significant cost savings without sacrificing quality or fitment.

    What are the most common engine parts that need replacement on International trucks?

    Based on customer orders and feedback, the most frequently replaced International engine parts include EGR valves and coolers (especially on 2007-2012 MaxxForce engines), fuel injectors, turbochargers, oil coolers, and high-pressure oil pumps for DT466 engines. We also see high demand for sensors like cam position sensors, IPR valves, and MAP sensors. These components typically show wear between 150,000-300,000 miles depending on maintenance and operating conditions.

    Do you provide installation instructions or technical support for engine parts?

    While we do not include printed installation instructions with most engine parts, our technical support team can provide guidance and answer installation questions. We recommend having a qualified diesel technician perform engine part installations, as many components require specific torque specifications and procedures. For DIY customers, we can direct you to service manual resources and provide torque specs when available. Call our tech line during business hours for assistance.

    What is your return policy on International engine parts?

    We offer a 30-day return policy on most International engine parts that are unused and in original packaging. Electronic components like sensors and modules must be unopened to qualify for return. Core exchange items like turbochargers and injectors require the old core to be returned within 30 days to receive your core credit. Custom-ordered or special-order engine parts are typically non-returnable. Please review the specific return policy on each product page or contact us before ordering if you have questions about a particular part.
