Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine and
emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets Ford specifications. See Capacities and
Specifications for more information.
3. Replace the filler cap. Turn it until you feel a strong resistance.
ENGINE COOLANT CHECK
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed in Scheduled Maintenance Information.
Note: Make sure that the level is at the FULL COLD level or within the
COLD FILL RANGE in the coolant reservoir.
Note: Coolant expands when it is hot. The level may extend beyond the
COLD FILL RANGE.
If the level is below the COLD FILL RANGE, add coolant immediately.
See Adding Engine Coolant in this chapter.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note: Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.

•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). 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 engine coolant.
Unscrew the cap slowly. Any pressure will escape as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specifications for more information.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of 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 have a Ford authorized dealer increase the
coolant concentration above 50%.
• A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant concentrations above 60% will decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
If you drive in extremely hot climates:
• It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion and freeze protection characteristics of the engine coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme climates should use prediluted
engine coolant for optimum cooling system and engine protection.

WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
4. If the coolant level is normal, you may restart your engine and
continue on.
5. If the coolant is low, add coolant, restart the engine and take your
vehicle to an authorized dealer. See Adding engine coolantin this
chapter for more information.
Refer to fail-safe cooling for additional information.
What You Should Know About Fail-Safe Cooling
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.
How Fail-Safe Cooling Works
If the engine begins to overheat:
• The engine coolant temperature gauge will move to the red (hot)
area.
•The service engine soon indicator will illuminate.
• The coolant temperature warning light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
• The engine power will be limited.
• The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.

When Fail-Safe Mode is Activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will have limited power, will not be
able to maintain high-speed operation, and may completely shut down
without warning, potentially losing engine power, power steering assist,
and power brake assist, which may increase the possibility of a crash
resulting in serious injury.
WARNING: Never remove the coolant reservoir cap while the
engine is running or hot. The hot coolant is under pressure and
may cause serious burns.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.
TRANSMISSION FLUID CHECK
6F35 TRANSMISSION (if equipped)
Note: Transmission fluid should be checked by an authorized dealer. If
required, fluid should be added by an authorized dealer.
The automatic transmission does not have a transmission fluid dipstick.
Refer to your scheduled maintenance information for scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, (i.e., if the transmission slips or
shifts slowly) or if you notice some sign of fluid leakage.
