Detailed Description

ATP Parts 101456 exhaust manifold is engineered to replace a damaged factory manifold and restore proper exhaust routing on the driver side. When an exhaust manifold cracks or warps, exhaust gases can escape into the engine compartment and create noise, odor, and heat-related concerns. This cast iron replacement is built to match original-style fitment and function on the Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis applications listed above. The included gasket and OE-style design help support a clean manifold-to-cylinder-head seal during repair.

This part cross-references Ford 4W7Z9431AA and 674904 for the same application.

Common Repair Symptoms

• Exhaust leak noise from the driver side of the engine
• Burning exhaust smell in the engine bay or cabin
• Visible cracking or warping in the manifold
• Reduced exhaust sealing at the cylinder head
• Heat damage around the manifold area

Installation Notes and Tips

Verify left-side fitment before installation and inspect the cylinder-head sealing surface for damage, carbon buildup, or old gasket material. Replace any worn fasteners or damaged studs during service, and confirm that the exhaust system is properly aligned before final tightening. Because exhaust manifold repairs involve high heat and tight clearances, allow the engine to cool fully before beginning work.

Quality Assurance

ATP Parts 101456 is backed by a lifetime warranty and built to OE standard replacement expectations for the listed applications. It is designed to restore exhaust sealing on 2003-2011 Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis left-side applications.
