Use only brake fluids certified to meet Ford specifications. Refer to
Lubricant Specifications in this chapter. DOT 3 fluid is recommended.
However, if DOT 3 is not available, DOT 4 fluid can be used.
2
Add the coolant type originally equipped in your vehicle.

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. Fill 6
mm to 14 mm (1/4 inch to 9/16 inch) below bottom of fill hole.
4
Ensure the correct automatic transmission fluid is used. MERCON and
MERCON V are not interchangeable. DO NOT MIX MERCON and
MERCON V. Refer to the scheduled maintenance guide to determine
the correct service interval.
