Product Details and Specifications

The Dorman 674-957 exhaust manifold features a regular grade type construction, ensuring it meets standard OEM requirements. Its round port shape is designed to match the exhaust ports on compatible Ford Explorer and Mercury Mountaineer models, promoting efficient exhaust gas evacuation.

Installation Notes and Tips

When installing the Dorman 674-957 exhaust manifold, ensure all old gasket material is thoroughly cleaned from the mounting surface to prevent leaks. Tighten the included studs and nuts to the manufacturer’s torque specifications to avoid warping the cast iron manifold. The included heat shield should be positioned correctly to protect adjacent components from heat exposure. It is recommended to inspect related exhaust system components during installation for any additional wear or damage.
