Oil Filter
Use a Motorcraft FL-400A Long-Life Oil Filter which meets Ford Specification ES-E1ZE-
6714-AA. These filters protect your engine by filtering harmful, abrasive, or sludgy particles
without blocking flow to vital engine parts.
To replace, use a filter wrench to remove filter.
Clean the filter mounting base. Lightly coat the gasket surface of the new filter with engine oil
and hand tighten until the gasket contacts the base, then tighten another half turn. Fill the
crankcase and run the engine to check for leaks. (Tighten filter more if necessary.)
WARNING - Do not handle a hot oil filter with bare hands. Continuous contact with used
motor oil has caused skin cancer in laboratory mice. Protect your skin by washing with
soap and water.
