1Add the coolant type originally equipped in your vehicle.2Fill 6 millimeter to 14 millimeter (1/4 inch to 9/16 inch) below bottom of fill hole.
Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated for
life. These lubricants do not need to be checked or changed unless a 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.3Ensure 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 yourscheduled maintenance informationto determine the
correct service interval.4Approximate dry fill capacity including transmission fluid cooling system, actual refill capacities
will vary based on vehicle application and transmission fluid cooling system (i.e. coolers size,
cooling lines, auxiliary cooler capacities). The amount of transmission fluid and fluid level should
be set by the indication on the dipstick’s normal operating range.5Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C945-A and the API Certification mark.
