2013 FORD FLEX overheating

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.

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.

Correct fluid level
The transmission fluid should be checked at normal operating
temperature 180°F-200°F (82°C-93°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
The transmission fluid level should be
targeted within the cross-hatch area
if at normal operating temperature
180°F-200°F (82°C-93°C).
High fluid level
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.Note:Fluid
level above the MAX level may cause
shift and/or engagement concerns
and/or possible damage.
High fluid levels can be caused by an overheating condition. If your
vehicle has been operated for an extended period at high speeds, in city
traffic during hot weather or pulling a trailer, the vehicle should be
turned off until normal operating temperatures are reached. Depending
on vehicle use, cooling times could take up to 30 minutes or longer.
Adjusting Automatic Transmission Fluid Levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in theTechnical
specificationssection in this chapter.
Note:Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint (250
ml) increments through the filler tube
until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
Note:An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.

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
Check every six months
Battery connections; clean if necessary
Body and door drain holes for obstructions; clean if necessary
Cooling system fluid level and coolant strength
Door weatherstrips for wear; lubricate if necessary
Hinges/latches/outside locks for proper operation; lubricate if necessary
Parking brake for proper operation
Safety belts and seat latches for wear and function
Safety warning lamps (brake, ABS, airbag, safety belt) for operation
Washer spray/wiper operation; clean or replace blades as necessary
