You 4.9L 6 cylinder guys will want to know this:
Ford Water Pump Caution Application: All Ford 4.9L (300 CID) engines. Problem: Possible engine block damage when installing replacement water pump. Cause: The water pump mounting hole flange thickness was increased by Ford after the 1992 model year. If a pump with thin mounting flanges is installed using mounting bolts from a 1993 or newer engine, the bolts will bottom on the front cylinder wall causing distortion. Solution: Compare the mounting flange thickness for each mounting hole of the replacement and original pump. They must be the same thickness. NEVER use mounting bolts from a 1993 or newer engine with the thinner flanges.
