Before you order
Match the engine code, not just the displacement: for heavy-duty diesels send the CPL / serial / arrangement number and EPA emissions year from the engine data plate. Ask about the core charge for your old engine, included accessories, and test results (compression or run video). Call +1 269-393-6376 or send a quote request.
Installation
Have the engine installed by a qualified technician with new fluids, filters, gaskets and thermostat, and follow the manufacturer’s break-in procedure. Labor is not covered by the parts warranty.
