CHECKING AND ADDING
ENGINE OIL
Use WSS-M2C153-F motor oil
CERTIFIED FOR GASOLINE
ENGINES by the American
Petroleum Institute.
Engine oils with an SAE 5W±30
viscosity and displaying the
American Petroleum Institute
certification mark are preferred for
your vehicle. They provide the best
engine performance, fuel economy
and engine protection for all
climates down to ±25ÉC (±15ÉF).
Do not use:
²ªnon-detergentº oils
²oils labeled API SA, SB, SC, SD,
SE, SF, or SG
²additional engine oil additives,
oil treatments or engine
treatments
Additional engine oil additives, oil
treatments, or engine treatments
are never needed and could, under
certain conditions, lead to engine
damage which is not covered by
your Ford warranty.
Synthetic engine oils which are
CERTIFIED and of the preferred
viscosity may be used in your
engine. The engine oil and oil filter
must still be changed according to
theService Guide.
Maintenance and care
140

Checking the engine oil
Check the engine oil every time
you fuel your vehicle.
Check the engine oil level more
frequently if the vehicle is carrying
a heavy load, towing a trailer,
idling for extended periods (like
police, taxi, or shuttle service
vehicles), or driven at high speeds
for extended periods of time.
To check engine oil:
1. Once the engine is warm, turn
the engine off. Make sure the
vehicle is parked on level ground.
2. Depress the parking brake.
Place the gearshift in P (Park).
3. Open the hood. Protect yourself
from engine heat.
4. Remove the engine oil dipstick
and wipe clean. Reinsert the
dipstick fully, then remove it again.
The oil level should be between
the MIN and MAX lines. If the oil
level lies between the MIN and
MAX lines, there is no need to
add.
5. If the oil level is below the MIN
line, add engine oil as necessary
and recheck the oil level. If the oil
level is above the letter ``M'' in
``MAX,'' engine damage and/or high
oil consumption may occur and
some oil must be removed from
the engine.
MAX MIN
Maintenance and care
141

Adding engine oil
If the fluid level is below the MIN
line, add engine oil. Add engine oil
through the oil filler cap and use a
funnel to pour oil into the opening.
Make sure you use a certified
engine oil of the preferred
viscosity.
Recheck the oil level. Make sure
that the oil level is not above the
MAX line on the dipstick.
Continuous contact with
USED motor oil has
caused cancer in laboratory rats.
Ford production and aftermarket
(Motorcraft) oil filters are designed
for added engine protection and
long life. If a replacement oil filter
is used that does not meet Ford
material and design specifications,
startup engine noises or knock
may be experienced.
It is recommended you use the
appropriate Motorcraft oil filter (or
another brand meeting Ford
specifications) for your engine
application.
CHECKING AND ADDING
BRAKE FLUID
Brake fluid should be checked and
refilled as needed at least once
each year.
Maintenance and care
142

Checking and adding washer
fluid for the liftgate
The opening for this reservoir is
located on the left side of the
vehicle above the tail lamp. Be
sure to close the cover after filling
and before closing the liftgate. The
reservoir must be filled slowly to
allow trapped air to escape. Use of
a funnel is recommended for easier
filling.
CHECKING AND ADDING
ENGINE COOLANT
Check the engine coolant level in
the reservoir at least once a
month.
If the engine coolant has not been
checked for a long period of time,
the engine coolant reservoir may
eventually empty. If this occurs,
add engine coolant to the coolant
reservoir. For more information on
engine coolant maintenance, refer
toAdding engine coolant to the
reservoirin this chapter.
Automotive fluids are not
interchangeable; do not
use engine coolant, antifreeze, or
windshield washer fluid outside
of their specified function and
vehicle location.
When adding engine coolant
Ford recommends Ford Premium
Cooling System fluid, which is an
optimized formula that will protect
all metals and rubber elastomers
used in Ford engines for four years

or 80,000 km (50,000 miles). It is
not necessary and not
recommended to use supplemental
coolant additives in your
gasoline-powered vehicle. These
additives may harm your engine
cooling system.
When you change or add engine
coolant, it is important to maintain
your engine coolant concentration
between 40% (-24ÉC [11ÉF]) and
60% (-52ÉC [-62ÉF]), depending on
your local climate conditions. A
coolant concentration below 40%
may cause the engine to overheat
on a warm day.
Do not use engine coolant that
does not meet all 14 requirements
of Ford Specification ESE-M97B44-A.
The use of an improper coolant
may void your warranty for the
engine cooling system. Use only a
premium nationally-recognized
brand name engine coolant.
Always dispose of used
automotive fluids in a responsible
manner. Follow your community's
standards for disposing of these
types of fluids. Call your local
recycling center to find out more
about recycling automotive fluids.
Adding engine coolant
Never remove the coolant
recovery cap while the
engine is running or hot.
Maintenance and care
146

1. Before you remove the coolant
recovery cap, turn the engine off
and let it cool. Even when the
engine is cool, be careful when
removing the recovery cap. Wrap a
thick cloth around the cap for safe
removal.
2. When the engine is cool, lift the
cap.
3. Step back while pressure
releases.
4. When you are sure that all the
pressure has been released,
remove the recovery cap.
5. Stand away from the reservoir
opening; hot steam may blow out
or hot engine coolant may even
splash out.
6. Add engine coolant until the
level is between the MAX and MIN
lines on the engine coolant
recovery reservoir.
Follow the recommended service
interval for changing engine
coolant as outlined in theService
Guide. For coolant recovery
reservoir capacity, refer to
Lubricant specificationsin the
Capacities and specifications
chapter.

Checking the cooling system
hoses
Before adding or replacing coolant,
inspect all cooling system hoses
for:
²deterioration
²leaks
²loose clamps
CHECKING AND ADDING
POWER STEERING FLUID
Check the power steering fluid at
least twice a year by completing
the following steps:
1. Start the engine.
2. When the engine coolant
temperature gauge reaches the
normal zone, turn off the engine.
