2. If the fluid level is low, start the engine.
3. While the engine idles, turn the steering wheel left and right several
times.
4. Turn the engine off.
For E-450 and E-550 vehicles with the Hydro-Boost Brake
System, do not press the brake pedal after the engine has been
turned off.
5. Recheck the fluid level on the dipstick. Do not add fluid if the level is
between the arrows in the FULL COLD range.
6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and
refilled as needed. Refer to the
scheduled maintenance guide for
the service interval schedules.
1. Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid from
a clean un-opened container until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specification ESA-M6C25–A. Refer toLubricant
specificationsin this chapter.

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
MERCONand MERCONV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONtype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONV type fluid.
MERCONand MERCONV type fluids are not interchangeable.
DO NOT mix MERCONand MERCONV. Use of a transmission
fluid that indicates dual usage (MERCONand MERCONV) in
an automatic transmission application requiring MERCONmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
7Approximate 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.
