Exhaust Manifold Cleaning and Inspection: Procedure
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
- Clean the exhaust manifold using a suitable solvent. Use a plastic scraping tool to clean the gasket sealing surfaces.
- Using the special tool (or a precision straight edge) and a feeler gauge, check the exhaust manifold sealing surface for warpage. If the warpage is greater than 0.76 mm (0.0299 in), install a new exhaust manifold.
NOTE:
New exhaust manifold gaskets, nuts and/or bolts must be installed when an exhaust manifold is serviced.
