1997 FORD EXPEDITION check engine

Never hold the steering wheel to
the extreme right or the extreme
left for more than a few seconds
when the engine is running. This
action could damage the power
steering pump.
Speed sensitive steering
The steering in your vehicle is
speed sensitive. At high speeds,
steering assist will decrease to
improve steering feel. At lower
speeds, maneuverability will be
increased.
If the amount of effort required to
steer your vehicle changes at a
constant vehicle speed, have the
power steering system checked by
your dealer or a qualified service
technician.

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
the ªService Guideº.
Checking the engine oil
Check the engine oil each time you
fuel your vehicle.
To check the oil:
1. Make sure the vehicle is on level
ground. If the engine is running,
turn the engine off and wait a few
minutes for the oil to drain into
the oil pan.
2. Set the parking brake and
ensure the gearshift is securely
latched in P.
3. Open the hood. Protect yourself
from engine heat.

4. Locate and carefully remove the
engine oil dipstick.
5. Wipe the dipstick clean. Insert
the dipstick fully, then remove it
again. The oil level should be in
the range shown on the dipstick.
6. If the oil level is below the
minimum line, add engine oil as
necessary. If the oil level is beyond
the maximum line, engine damage
or high oil consumption may occur
and some oil must be removed
from the engine by a service
technician.
7. Put the dipstick back in and
ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For
instructions, refer toChecking the
engine oilin this chapter.
2. If the fluid level is not within
the normal range, add only
certified engine oil of the preferred
viscosity. Add engine oil through
the oil filler cap. Remove the filler
cap and use a funnel to pour oil in
the opening.
3. Recheck the oil level. Make sure
the oil level is not above the full
mark on the dipstick.
Continuous contact with
usedmotor oil has caused
cancer in laboratory mice.

Changing the engine oil and
filter
Change your engine oil and filter
according to the following
kilometers (mileage) and time
requirements, whichever occurs
first:
²Normal Schedule ± 8,000 km
(5,000 miles) or six months.
²Severe Duty Schedule ± 5,000
km (3,000 miles) or three
months. Severe duty operation
would include extensive idling,
trailer towing, driving in severe
dust and police, taxi or delivery
service.
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:

Washer fluid in the liftgate
reservoir
Washer fluid for liftgate wiper and
washer operation is supplied by
the washer fluid reservoir located
in the engine compartment. For
information on adding fluid to this
main reservoir, refer toWasher
fluid in the windshield reservoir
in this chapter.
CHECKING AND ADDING
ENGINE COOLANT
Adding engine coolant
Do not put engine coolant
in the container for the
windshield washer fluid.
If sprayed on the windshield,
engine coolant could make it
difficult to see through the
windshield.
When the engine is cool, add a
50/50 mixture of engine coolant
and water to the engine coolant
recovery reservoir Ð DO NOT
ADD DIRECTLY TO THE
RADIATOR. Add straight water
only in an emergency, but you
should replace it with a 50/50
mixture of coolant and distilled
water as soon as possible.

Check the coolant level in the
coolant recovery reservoir the next
few times you drive the vehicle. If
necessary, add enough of a 50/50
mixture of coolant and water to
bring the liquid level to the fill line
on the reservoir.
Never remove the coolant
recovery cap while the
engine is running or hot.
If you must remove the coolant
recovery cap, follow these steps to
avoid personal injury:
1. Before you remove the cap, turn
the engine off and let it cool.
2. When the engine is cool, wrap a
thick cloth around the cap. Slowly
turn cap counterclockwise to the
first stop.
3. Step back while the pressure
releases.
4. When you are sure that all the
pressure has been released, use
the cloth to press the cap down,
turn it counterclockwise and
remove it.
Use Ford Premium Cooling System
Fluid E2FZ-19549±AA (in Canada,
Motorcraft CXC-8±B) or an
equivalent premium engine coolant
that meets Ford Specification
ESE-M97B44±A. Ford Premium
Engine Coolant is an optimized
formula that will protect all metals
and rubber elastomers used in
Ford cooling systems for 4 years or
80,000 km(50,000 miles).
Maintenance and care
166

Do not use alcohol or methanol
antifreeze or any engine coolants
mixed with alcohol or methanol
antifreeze. Do not use
supplemental coolant additives in
your vehicle. These additives may
harm your engine cooling system.
The use of an improper coolant
may void the warranty of your
vehicle's engine cooling system.
Recycled engine coolant
Ford Motor Company recommends
that Ford and Lincoln-Mercury
dealers use recycled engine coolant
produced by Ford-approved
processes. Not all coolant recycling
processes produce coolant which
meets Ford specification
ESE-M97B44±A, and use of such
coolant may harm engine and
cooling system components.
Always dispose of used
automotive fluids in a responsible
manner. Follow your community's
regulations and standards for
recycling and disposing of
automotive fluids.
Coolant refill capacity
To find out how much fluid your
vehicle's cooling system can hold,
refer toRefill capacitiesin the
Capacities and specifications
chapter.
Have your dealer check the engine
cooling system for leaks if you have
to add more than a liter (quart) of
engine coolant per month.
