- Description:
This is a brand new genuine Ford OEM left hand heat shield carrying part number LC3Z-9Y427-A, fitting 20-25 F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Power Stroke diesel. The heat shield mounts above the driver side exhaust manifold and turbocharger area and protects nearby wiring, hoses, and plastic components from radiated exhaust heat. Heat shields on 6.7L PSD trucks are commonly damaged by impact during routine service work, corroded through after years of road salt and slush exposure, or warped from sustained extreme heat under heavy towing. A missing or damaged heat shield exposes downstream components to elevated temperatures that can cook wiring harness insulation, embrittle vacuum lines, and accelerate aging of nearby plastic intake components, leading to a cascade of secondary failures. Always replace the shield if it shows perforation, warpage, or missing mounting tabs. Replacement requires removing the upper engine cover and the bolts retaining the shield to the manifold or head; verify mounting hardware is in serviceable condition before reassembly. Sold individually as a single shield; mounting bolts and clips are separate service items. Verify left hand position on the diagram before ordering. Backed by Ford's OEM parts limited warranty.
