2012 FORD EXPLORER cooling

How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature gauge will move to the red (hot)
area.
•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
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.

Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the MIN and
MAX lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range, the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid (6F50/6F55) (if equipped)
Refer to yourscheduled maintenance informationfor 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.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). 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 to
allow the fluid to cool before checking. Depending on vehicle use,
cooling times could take up to 30 minutes or longer.
WARNING:The dipstick cap and surrounding components may
be hot; gloves are recommended.

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 the
Maintenance product specifications and capacitiessection in this
chapter.
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.
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
Checking automatic transmission fluid (6F35) (if equipped)
The automatic transmission does not have a transmission fluid dipstick.
Refer to yourscheduled maintenance informationfor 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.

•Lubricate all hood, door and trunk lid hinges, and latches with a light
grade oil. See theCleaningchapter for more information.
•Cover interior trim to prevent fading.
•Keep all rubber parts free from oil and solvents.
Engine
•The engine oil and filter should be changed prior to storage, as used
engine oil contain contaminates that may cause engine damage.
•Start the engine every 15 days. Run at fast idle until it reaches normal
operating temperature.
•With your foot on the brake, shift through all the gears while the
engine is running.
Fuel system
•Fill the fuel tank with high-quality fuel until the first automatic shutoff
of the fuel pump nozzle.
Note:During extended periods of vehicle storage (30 days or more),
fuel may deteriorate due to oxidation. Add a quality gas stabilizer
product to the vehicle fuel system whenever actual or expected storage
periods exceed 30 days. Follow the instructions on the additive label.
The vehicle should then be operated at idle speed to circulate the
additive throughout the fuel system.
Cooling system
•Protect against freezing temperatures.
•When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and 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, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
Note:If battery cables are disconnected, it will be necessary to reset
memory features.
