Detailed Description

ATP Parts 101420 is an exhaust manifold designed for the left side of the engine on compatible Ford and Lincoln platforms. Exhaust manifolds carry burned gases away from the engine and into the exhaust system; when the manifold fails, hot exhaust can escape into the engine compartment and create a safety concern. This replacement manifold is engineered to restore the original exhaust routing and sealing performance on the listed Ford F-150, Ford Expedition, Lincoln Navigator, and Lincoln Mark LT fitments.

Use ATP Parts 101420 when servicing a 2004-2010 Ford F-150 left exhaust manifold, a 2005-2014 Ford Expedition left exhaust manifold, a 2005-2014 Lincoln Navigator left exhaust manifold, or a 2006-2008 Lincoln Mark LT left exhaust manifold. The part number 101420 is also useful when searching for an OE-style exhaust manifold replacement for these applications.

What It Helps Fix

• Exhaust leaks at the manifold
• Ticking or puffing noises from a cracked manifold
• Burning exhaust smell in the engine bay
• Loss of exhaust sealing at the cylinder head
• Heat escaping into the engine compartment

Installation Notes and Tips

Verify left-side fitment before ordering and match the vehicle year, make, and model to the listed applications. Inspect the cylinder head sealing surface, fasteners, and adjoining exhaust components during installation so the replacement manifold can seal correctly. Confirm that the replacement part number 101420 matches the original application before beginning service.

Quality Assurance
