F-250 Light Duty (1999 year). Manual — part 44

2. Visually inspect the fluid level.

3. If necessary, add brake fluid until
the level reaches MAX. Do not fill
above this line.

4. Use only a DOT 3 brake fluid
certified to meet Ford specifications.
Refer to Lubricant specifications in the Capacities and specifications
chapter.

Brake fluid is toxic.

If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.

Do not let the reservoir for the master cylinder run dry. This
may cause the brakes to fail.

CLUTCH FLUID (IF EQUIPPED)

Check the clutch fluid level. Refer to the Scheduled Maintenance Guide
for the service interval schedules.

Use only a DOT 3 brake fluid designed to meet Ford specifications. Refer
to Capacities and specifications.

For vehicles equipped with the 5–speed manual transmission,
during normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, maintain the fluid level at the
step in the reservoir.

For vehicles equipped with the 6–speed manual transmission,
during normal operation, the fluid level in the clutch reservoir will drop
slightly. As this occurs, maintain the fluid level at the step in the
reservoir.

1. Clean the reservoir cap before
removal to prevent dirt and water
from entering the reservoir.

2. Remove cap and rubber
diaphragm from reservoir.

3. Add fluid until the level reaches
the step in the reservoir.

4. Reinstall rubber diaphragm and
cap onto reservoir.

WINDSHIELD WASHER FLUID

Checking and adding washer fluid

Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a

symbol.

If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.

Do not put engine coolant in the container for the windshield
washer fluid.

ENGINE COOLANT

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become empty. If this occurs, add
engine coolant to the reservoir. For more information on engine coolant
maintenance, refer to Adding engine coolant in this chapter.

Automotive fluids are not interchangeable; do not use engine coolant,
antifreeze or windshield washer fluid outside of its specified function and
vehicle location.

Adding engine coolant

Use only Ford Premium Engine Coolant E2FZ-19549–AA (in
Oregon, F5FZ-19549–CC, in Canada, Motorcraft CXC-10) or a
premium engine coolant that meets Ford specification
ESE-M97B44–A.
• DO NOT USE Ford Extended Life Engine Coolant

F6AZ-19544–AA (orange in color).

• DO NOT USE a DEX-COOL威 engine coolant or an equivalent

engine coolant that meets Ford specification WSS-M97B44–D.

• DO NOT USE alcohol or methanol antifreeze or any engine

coolants mixed with alcohol or methanol antifreeze.

• DO NOT USE supplemental coolant additives in your vehicle.

These additives may harm your engine’s cooling system.

• DO NOT MIX recycled coolant and conventional coolant

together in your vehicle. Mixing of engine coolants may harm
your engine’s cooling system.

• The use of an improper coolant may harm engine and cooling

system components and may void the warranty of your vehicle’s
engine cooling system.

• Use only the type of coolant with which your vehicle was

originally equipped. If you are unsure which type of coolant
your vehicle requires, contact your local dealer.

Do not put engine coolant in the container for the windshield
washer fluid.

If sprayed on the windshield, engine coolant could make it difficult to see
through the windshield.

When the engine is cool, add a 50/50 mixture of engine coolant and
distilled water to the engine coolant reservoir.

Plain water may be added in an emergency, but you must replace it with
a 50/50 mixture of coolant and distilled water as soon as possible.

Check the coolant level in the coolant reservoir the next few times you
drive the vehicle. If necessary, add enough of a 50/50 mixture of coolant
and distilled water to bring the liquid level to the fill line on the
reservoir.

Never remove the coolant reservoir cap while the engine is
running or hot.

If you must remove the coolant reservoir cap, follow these steps to avoid
personal injury:

1. Before you remove the cap, turn the engine off and let it cool.

2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.

3. Step back while the pressure releases.

4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.

Change your engine coolant according to the appropriate schedule listed
in the Scheduled Maintenance Guide.
