Detailed Description

This exhaust manifold is designed for rear-position service on the Ford Windstar and Ford Freestar, covering 1999-2003 Windstar rear and 2004-2007 Freestar rear applications. Dorman 674-366 follows the original manifold layout for the specified vehicles and uses cast iron construction to handle exhaust heat and long-term underhood exposure.

Installation Notes and Tips

Verify rear-position fitment before installation on your Ford Windstar or Ford Freestar. Inspect the cylinder head flange, fasteners, and downpipe connection surfaces for damage or corrosion before assembly. Use the included gasket and the specified mounting hardware from the package contents, and follow factory torque procedures to help achieve a secure seal.
