leak is suspected, service is required or the axle assembly has been
submerged in water. The axle lubricant should be changed any time the
rear axle has been submerged in water.
2 Add 236 ml (8 oz.) of Additive Friction Modifier C8AZ-19B546-A or
equivalent meeting Ford Specification EST-M2C118-A for complete refill
of Traction-Lok axles.
3 Use Ford Premium Engine Coolant (green in color). DO NOT USE Ford
Extended Life Engine Coolant (orange in color). Refer to Adding engine
coolant, in the Maintenance and Care chapter.
4 Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to your scheduled maintenance guide to determine
the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCON
௡ and MERCON௡ V. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCON
௡ type
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCON
௡ V type fluid.
MERCON
௡ and MERCON௡ V type fluids are not interchangeable.
DO NOT mix MERCON
௡ and MERCON௡ V. Use of a transmission
fluid that indicates dual usage (MERCON
௡ and MERCON௡ V) in
an automatic transmission application requiring MERCON
௡ may
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
5 Service refill capacity is determined by filling the transmission to the
bottom of the filler hole with the vehicle on a level surface.
6 Indicates only approximate dry-fill capacity. Some applications may
vary based on cooler size and if equipped with an in-tank cooler. The
amount of transmission fluid and fluid level should be set by the
indication on the dipstick’s normal operating range.
