Dorman 674-357 is a stainless steel exhaust manifold engineered to match the fit and function of the original part on select Ford and Mercury applications. It is built for the right side and includes the gasket, heat shield, and downpipe hardware needed for a complete exhaust manifold repair.

• Stainless steel construction with a natural finish
• Right-side exhaust manifold for select 1996-1998 vehicles
• Oval port shape for OE-style fitment
• Includes manifold gasket, heat shield, and mounting hardware
• Direct replacement for the original manifold on specified applications

Detailed Fitment and Design

This exhaust manifold is made for 1996-1997 Ford Explorer, right; 1998 Ford Explorer, right, to 2/98; 1997 Mercury Mountaineer, right; and 1998 Mercury Mountaineer, right, to 2/98. Dorman 674-357 is shaped to align with the original exhaust routing and flange layout, helping restore proper exhaust sealing on the Ford Explorer and Mercury Mountaineer right-side manifold location.

This part cross-references ATP 101136 and OE number F77Z9430JA for the same application.

• Heat shield deterioration around the manifold area

Installation Notes and Tips

Verify right-side fitment before ordering, especially for 1998 Ford Explorer and 1998 Mercury Mountaineer models built to 2/98. Inspect the cylinder head surface, exhaust flange, and fastener threads before installation. Replace worn sealing surfaces and follow the vehicle service procedure for torque sequence and exhaust alignment.
