CAUTION:
PREVENT CYLINDER BLOCK CONTAMINATION. ALWAYS USE NECESSARY PRECAUTIONS TO PREVENT OLD SEALER OR
GASKET MATERIAL FROM FALLING INTO THE CYLINDER BLOCK.
d.
After all the parts have been cleaned, they must be wiped down with a cleaner that leaves no residue or film such as Metal Surface Cleaner
(F4AZ-19A536-RA) or denatured alcohol.
CAUTION:
NEVER USE CARBURETOR CLEANER OR OTHER PETROLEUM PRODUCTS ON AREAS TO BE SEALED. THEY LEAVE A
HYDROCARBON RESIDUE THAT RESISTS THE ADHESIVE ACTION OF SEALANTS. AVOID THE USE OF SOAP AND WATER AS
CLEANERS. SOAP FILM RESISTS THE SEALANTS ADHESIVE ACTION.
e.
Clean the transmission "BELLHOUSING" area, the rear of the cylinder block and the rear engine plate of ALL oil residue.
f.
Place a bead of Ford Silicone Sealer (F1AZ-19562-A) in the oil pan gasket groove at the corner of the radius areas at the front and rear of
the oil pan.
g.
Place the oil pan gasket (FOTZ-6710-C) in place in the groove in the oil pan.
h.
Place a bead of Ford Silicone Sealer (F1AZ-19562-A) in the corners where the rear main cap meets the cylinder block, at the corner areas of
the radius area on the front cover and the front cover to cylinder block joint.
i.
Set the oil pan in place and snug the four (4) pan nuts.
j.
Align the rear face of the oil pan with the rear face of the cylinder block.
NOTE:
IF THE REAR FACE OF THE OIL PAN CANNOT BE ALIGNED WITHIN .0100" (.254 mm) OF THE REAR FACE OF THE CYLINDER
BLOCK, THE APPROPRIATE SHIMS MUST BE USED.
k.
Install the remaining oil pan bolts and torque to 5-7 lb.ft. (7-10 N-m).

HYDROCARBON RESIDUE THAT RESISTS THE ADHESIVE ACTION OF SEALANTS. AVOID THE USE OF SOAP AND WATER AS
CLEANERS. SOAP FILM RESISTS THE SEALANTS ADHESIVE ACTION.
h.
Clean the transmission "BELLHOUSING AREA", the rear of the cylinder block and the rear engine plate of ALL oil residue.
