Ford F-250 Super Duty (1999 year). Manual — part 45

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.

Recycled engine coolant

Ford Motor Company recommends that Ford and Lincoln-Mercury
dealers use recycled engine coolant produced by Ford-approved
processes.

Not all coolant recycling processes produce coolant which meets Ford
specification ESE-M97B44–A, and use of such coolant may harm engine
and cooling system components.

Always dispose of used automotive fluids in a responsible manner.

Follow your community’s regulations and standards for recycling and
disposing of automotive fluids.

Coolant refill capacity

To find out how much fluid your vehicle’s cooling system can hold, refer
to Refill capacities in the Capacities and specifications chapter.

Have your dealer check the engine cooling system for leaks if you have
to add more than 1.0 liter (1.0 quart) of engine coolant per month.

Severe winter climate

If you drive in extremely cold climates (less than –36°C [–34°F]), it may
be necessary to increase the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the coolant concentration in
your vehicle is such that the coolant will not freeze at the temperature
level in which you drive during winter months. Never increase the
coolant concentration above 60%. Increased engine coolant
concentrations above 60% will decrease the freeze protection
characteristics of the engine coolant. Vehicles driven year-round in
non-extreme climates should use a 50/50 mixture of engine coolant and
distilled water for optimum freeze protection.

What you should know about fail-safe cooling (if equipped)

If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
