Detailed Description

This exhaust manifold is precision-engineered to match the original part on selected Ford E-Series vans, F-Series trucks, and Bronco applications. The cast iron body supports long-term exhaust heat exposure, while the OE-style shape and port layout help maintain proper exhaust routing on the rear side of the engine. If you are replacing a cracked or leaking manifold on a Ford F-150, Ford F-250, or Ford E-350 Econoline, Dorman 674-186 provides a direct-fit repair solution. This part cross-references ATP 101018 for the same application.

Installation Notes and Tips

Inspect the cylinder head surface, fasteners, and adjoining exhaust components for damage or corrosion before installation. For best results, replace any worn sealing components and follow the vehicle service procedure for torque sequence and heat-cycle recheck.
