ENGINE COOLANT CHECK -
2.0L ECOBOOST™/3.7L
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information.
See Scheduled Maintenance (page
440
).
Note: Make sure that the 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
Note: If the level is at the MIN mark,
below the MIN mark, or empty, 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 degrees (-34 C) and
-34 F (-37 C).
268
Maintenance

•
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
(page 325).
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.
Always dispose of used automotive
fluids in a responsible 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/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.

Maintenance

3. If this is not possible, wait a short
period for the engine to cool.
4. Check the coolant level and replenish if low.
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.
AUTOMATIC
TRANSMISSION FLUID
CHECK
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.
Have an authorized dealer check and
change the transmission fluid and
filter at the correct service interval.
See Scheduled Maintenance (page
440). Your transmission does not
consume fluid. However, the fluid level
should be checked if the transmission
is not working properly, or if you notice
some sign of fluid leakage.
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. 6F35/HF35 transmission
