Product Details and Specifications

The Dorman 674-696XD exhaust manifold is specifically designed for Ford F-250 Super Duty, F-350, and F-350 Super Duty trucks, ensuring compatibility and proper fitment. Made from cast iron, this manifold withstands high temperatures and resists cracking or warping over time. The round port shape and 1.5-inch collector port diameter facilitate smooth exhaust gas flow, which helps maintain engine efficiency. With a tube wall thickness of 4.5 mm, the manifold offers structural integrity under demanding operating conditions. The metallic gray finish provides additional protection against rust and corrosion. This exhaust manifold does not include an oxygen sensor port, so it is intended for applications where sensor relocation or alternative sensor setups are used.

Common Applications and Problem Solving

• Replacement for cracked or warped exhaust manifolds on Ford F-250 and F-350 Super Duty trucks
• Eliminates exhaust leaks caused by damaged or deteriorated manifolds
• Restores proper exhaust flow to improve engine performance and reduce emissions
• Addresses heat damage issues with included heat shield for better thermal management
• Ensures secure mounting with 8 mounting holes for stable installation

Installation Notes and Tips

When installing the Dorman 674-696XD exhaust manifold, ensure all old gasket material is thoroughly cleaned from the mounting surface to prevent leaks. Use the included gasket and heat shield to maintain proper sealing and heat protection. Tighten mounting bolts evenly in a crisscross pattern to the manufacturer’s torque specifications to avoid warping. Since this manifold does not have an oxygen sensor port, verify sensor placement compatibility before installation.
