CLEANING AND INSPECTION (Continued)
4. NOTE: On 3.8L engines if paint is observed on
the filler neck sealing surface, remove it using
paint thinner.
Inspect the filler neck opening for rust or dirt
particles on the sealing surface at the
bottom of
the filler neck opening. Use a clean cloth and wipe
the sealing surface to remove any rust or dirt
particles.

NOTE: With the introduction of a new radiator braze
process, there is no longer an approved service
method for repairing radiator core leaks. Due to the
type
of
flux used during brazing, the two component
epoxy materials previously used will not adhere to the
aluminum radiator core. If the radiator core leaks, the
radiator (8005) should be replaced.
External
Install steel or brass plugs in the transmission oil
cooler fittings before cleaning (if equipped). Keep
them installed during the entire service operation.
NOTE: Do not use a metal brush to clean an aluminum
core. Use only horsehair, bristle or nylon brushes.
Clean the outside of aluminum core with a soft bristle
brush, warm water and a mild household liquid
detergent. Rinse with clear water.
Internal
NOTE: Do not use caustic cleaning solutions or
copper I brass radiator cleaning agents on aluminum
radiators.
To clean internal aluminum tubes use sonic cleaning
equipment. Rinse the core with clean water when
completed.
Fan Blade
WARNING: DO NOT ATTEMPT TO STRAIGHTEN
OR SERVICE A FAN BLADE (8600). REPLACE FAN
BLADE IF HUB OR BLADES ARE DAMAGED.
Check fan blade for cracks or damage. Replace as
described.

water and coolant meeting Ford specification
ESE-M97844-A such as Premium Cooling System
Fluid E2FZ-1 9549-AA or -B (in Oregon,

coolant or equivalent.
All figures shown are actual but may vary

percent due to system variations.
Most service refills will only take 80 percent of
capacity listed because some engine coolant does not
drain unless cylinder block drain plugs are removed
(if
equipped).
