Product Details and Specifications

The Dorman 674-115 exhaust manifold is designed specifically for Ford F-150 and Lincoln Mark LT trucks, ensuring precise fitment and compatibility. Its cast iron construction withstands the high heat and pressure generated by the engine exhaust gases. The round port shape optimizes exhaust gas flow, contributing to engine efficiency and emission control. This manifold does not include an oxygen sensor port, so it is intended for applications where the sensor is located elsewhere in the exhaust system. The included inlet gasket and mounting hardware facilitate a secure and leak-free installation.

Common Applications and Problem Resolution

• Replacement for cracked or warped exhaust manifolds causing exhaust leaks
• Restores proper exhaust flow to improve engine performance and reduce noise
• Addresses manifold gasket failures that lead to exhaust fumes entering the cabin
• Suitable for repairing manifolds damaged by corrosion or heat stress
• Helps maintain emission standards by ensuring proper exhaust routing

Installation Notes and Tips

When installing the Dorman 674-115 exhaust manifold on Ford F-150 or Lincoln Mark LT vehicles, ensure all old gasket material is thoroughly cleaned from the mounting surfaces. Use the included inlet gasket and hardware to secure the manifold tightly, following manufacturer torque specifications. Since this manifold does not have an oxygen sensor port, verify sensor placement in your vehicle’s exhaust system before installation. Proper installation will help prevent exhaust leaks and maintain engine efficiency.
