ENGINE COOLANT CHECK WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling system
can burn you badly. Also, spilling coolant on
hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine coolant
could make it difficult to see through the
windshield. WARNINGS
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure relief cap.
The cooling system is under pressure. Steam
and hot liquid can come out forcefully when
you loosen the cap slightly. Do not add coolant further than the
MAX mark.
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 456).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
Note:
Automotive fluids are not
interchangeable. Take care not to put
engine coolant in the windshield washer fluid
reservoir or windshield washer fluid in the
engine coolant reservoir.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.

It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system. See Capacities
and Specifications (page 328). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 328).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
Note: Coolants marketed for all makes and
models may not be approved to Ford
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty. If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Capacities and
Specifications
(page 328).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage. Note:
During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
Note: In case of emergency, you can add a
large amount of water without coolant in
order to reach a vehicle service location.
Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing. When you reach a service
location, you must have the cooling system
drained and refilled with prediluted coolant
approved to the correct specification.
See
Capacities and Specifications (page 328).
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
269
Navigator (TB5) Canada/United States of America, enUSA, First Printing Maintenance

Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community's regulations and standards for
recycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
328).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolant
temperature gauge moves toward the red
zone: A warning lamp illuminates and a
message may appear in the
information display.

Cooling system
•
Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling system
leaks and that fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
battery cables to maintain battery charge
for quick starting.
Note: It is necessary to reset memory
features if battery cables are disconnected.
Brakes
• Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure. Miscellaneous
•
Make sure all linkages, cables, levers and
pins under your vehicle are covered with
grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m) every
15 days to lubricate working parts and
prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt or
grease film build-up on window surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected during
storage such as mice or squirrel nests.
• Check the exhaust for any foreign
material that may have collected during
storage.
• Check tire pressures and set tire inflation
per the Tire Label. •
Check brake pedal operation. Drive your
vehicle 15 ft (4.5 m) back and forth to
remove rust build-up.
• Check fluid levels (including coolant, oil
and gas) to make sure there are no leaks,
and fluids are at recommended levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
Contact an authorized dealer if you have any
concerns or issues.
