2013 FORD FLEX engine overheat

Trailer Lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Do not
connect trailer lamps directly to your vehicle’s tail lamps. This can cause
damage to your vehicle’s electrical system. Contact your authorized
dealer or trailer rental agency for proper instructions and equipment for
hooking-up trailer lamps.
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in fire. Contact your authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Before Towing a Trailer
Practice turning, stopping and backing-up to get the feel of the
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers) and do not make full-throttle starts.
•Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
•Place the gearshift lever in P (Park) to aid in engine/transmission
cooling and A/C efficiency during hot weather while stopped in traffic.
•Turn off the speed control. The speed control may turn off
automatically when you are towing on long, steep grades.
•Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as they may overheat and become less
effective.
•If your transmission is equipped with the grade assist feature, use this
feature when towing. This provides engine braking and helps eliminate
excessive transmission shifting for optimum fuel economy and
transmission cooling.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
•Avoid parking on a grade. However, if you must park on a grade, place
wheel chocks under the trailer’s wheels.

WARNING: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 the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets or cooling system sealants/additives as
they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. 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.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained, chemically cleaned with Motorcraft
Premium Cooling System Flush, and refilled with prediluted engine
coolant as soon as possible. Water alone (without engine coolant) can
cause engine damage from corrosion, overheating or freezing.
•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 Specificationsfor 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:
Note:It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
Note:A coolant concentration of 60% will provide improved freeze point
protection. Increased 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:
Note:It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
Note:A coolant concentration of 40% will provide improved overheat
protection. Decreased engine coolant concentrations below 40% will
decrease the corrosion/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.
Engine fluid temperature management (EcoBoost™ engine only)
WARNING:To reduce the risk of collision and injury, be prepared
that the vehicle speed may reduce and the vehicle may not be able
to accelerate with full power until the fluid temperatures reduce.
Your vehicle has been designed to pull a trailer, but because of the added
load, the vehicle’s engine may temporarily reach higher temperatures
during severe operating conditions such as ascending a long or steep
grade while pulling a trailer in hot ambient temperatures.

At this time, you may notice your engine coolant temperature gauge
needle move toward the H and the POWER REDUCED TO LOWER
TEMP message may appear on the message center.
You may notice a reduction in the vehicle’s speed caused by reduced
engine power. Your vehicle has been designed to enter this mode if
certain high temperature/high load conditions take place in order to
manage the engine’s fluid temperatures. The amount of speed reduction
will depend on the vehicle loading, towing, grade, ambient temperature,
and other factors. If this occurs, there is no need to pull off the road.
The vehicle can continue to be driven while this message is active.
The air conditioning may also cycle on and off during severe operating
conditions to protect overheating of the engine. When the engine coolant
temperature decreases to a more normal operating temperature, the air
conditioning will turn on once again.
If you notice any of the following:
•
the engine coolant temperature gauge moves fully into the red (hot) area
•the coolant temperature warning light illuminates
•the service engine soon indicator illuminates
1.
Pull off the road as soon as safely possible and place the vehicle in P
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant
level.
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. SeeAdding 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 and:
The coolant temperature warning light will illuminate.
The service engine soon indicator 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
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.

Additives and Chemicals
Ford Motor Company recommended additives and chemicals are listed in
this book and in theWorkshop Manual.Additional chemicals or additives
not approved by Ford and are not recommended as part of normal
maintenance. Please consult yourWarranty Manualfor complete warranty
information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic and,
by itself, does not necessarily indicate a concern or that the fluid needs to
be changed. However, discolored fluids that also show signs of overheating
and/or foreign material contamination should be inspected immediately by a
qualified expert such as the factory-trained technicians at your dealership.
Your vehicle’s oils and fluids should be changed at the specified intervals or
in conjunction with a repair. Flushing is a viable way to change fluid for
many vehicle sub-systems during scheduled maintenance. It is critical that
systems are flushed only with new fluid that is the same as that required to
fill and operate the system, or using a Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
every month or at six months intervals.
Check every month
Engine oil level
Function of all interior and exterior lights
Tires for wear and proper pressure, including spare
Windshield washer fluid level
