1998 FORD TAURUS check engine

increase the engine coolant concentration above
60%. Leave a 50/50 mixture of engine coolant and
water in your vehicle year-round in non-extreme
climates.
CHECKING AND ADDING POWER STEERING
FLUID
Check the power
steering fluid. Refer to
the ªService Guideº for
the service interval
schedules. If adding
fluid is necessary, use
only MERCONtAT F.
1. Start the engine and let it run until it reaches
normal operating temperature (the engine coolant
temperature gauge indicator will be near the center
of the normal area between H and C).
2. While the engine idles, turn the steering wheel
left and right several times.
3. Turn the engine off.
Perform steps 4 and 5 following the procedure for
your engine.

4. Check the fluid level
on the dipstick. It
should be between the
arrows in the FULL
HOT range. Do not add
fluid if the level is
within this range.

5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
FULL HOT range. Be sure to put the dipstick back
in the reservoir.

4. Check the fluid level
in the reservoir. It
should be between the
MIN and MAX lines. Do
not add fluid if the
level is within this
range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
range between the MIN and MAX lines. Be sure to
put the cap back on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your ªService Guideº for scheduled intervals
for fluid checks and changes. Your transaxle does
not consume fluid. However, the fluid level should
be checked if the transaxle is not working properly,
i.e., if the transaxle 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 30 km [20 miles]). 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 for about 30 minutes to allow
fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it
reaches normal operating temperature.

2. Park the vehicle on a level surface and engage the
parking brake.
3. With the parking brake engaged and your foot on
the brake pedal, start the engine and move the
gearshift lever through all of the gear ranges. Allow
sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean,
dry lint free rag.
6. Install the dipstick making sure it is fully seated in
the filler tube.
7. Remove the dipstick and inspect the fluid level.
The fluid should be in the designated areas for
normal and room temperature.
Low fluid level
Do not drive the
vehicle if the fluid level
is at the bottom of the
dipstick and the outside temperatures are above
10ÉC (50ÉF).
Correct fluid level
The transmission fluid should be checked at normal
operating temperatures 66ÉC-77ÉC (150ÉF-170ÉF) on
a level surface. The normal operating temperature
can be reached after approximately 30 km (20
miles) of driving.
The transmission fluid
should be in this range
if at normal operating
temperature (66ÉC-77ÉC [150ÉF-170ÉF]).

2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
If the ªService Engine Soon/Check Engine ª indicator
comes on and stays on when you start the engine,
the fuel filler cap may not be properly installed.
Turn off the engine, remove the fuel filler cap and
reinstall it being careful to align the cap properly.
If you must replace the fuel filler cap, replace
it with an authorized Motorcraft part. The
customer warranty may be void for any damage
to the fuel tank or fuel system if an authorized
Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If
the fuel filler cap is venting vapor or if you
hear a hissing sound, wait until it stops before
completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
If you do not use the proper fuel filler cap,
the pressure in the fuel tank can damage
the fuel system or cause it to work improperly in a
collision.

Do not make any unauthorized changes to your
vehicle or engine. By law, vehicle owners and anyone
who manufactures, repairs, items, sells, leases,
trades vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an emission
control device or prevent it from working.
Information about your vehicle's emission system is
on the Vehicle Emission Control Information Decal
located on or near the engine. This decal identifies
engine displacement and gives some tune up
specifications.
Please consult your ªWarranty Guideº for complete
emission warranty information.
Readiness for inspection/maintenance (I/M)
testing
In some localities, it may be a legal requirement to
pass an I/M test of the on-board diagnostic (OBD-II)
system. If your ªCheck Engine/Service Engine Soonº
light is on, refer to the description in theWarning
Lights and Chimessection of theInstrumentation
chapter. Your vehicle may not pass the I/M test with
the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has
just been serviced, the OBD-II system is reset to a
ªnot ready for I/M testº condition. To ready the
OBD-II system for I/M testing, a minimum of 30
minutes of city and highway driving is necessary as
described below:
²First, at least 10 minutes of driving on an
expressway or highway.
²Next, at least 20 minutes driving in stop-and-go,
city-type traffic with at least four idle periods.
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.

1If your engine coolant is green in color, use Ford
Premium Cooling System Fluid. If your engine
coolant is orange in color, use Ford Extended Life
Engine Coolant. Refer toLubricant Specifications.
Ensure correct automatic transmission fluid is used
for a specific application. Check the container to
verify the fluid is MERCONtand/or MERCONtV
approved. Some fluids have been approved as
meeting both MERCONtand MERCONtV
requirements and will be labeled as such. Fluids
labeled as meeting only MERCONtor only
MERCONtV requirements must not be used
interchangeably. DO NOT mix MERCONtand
MERCONtV. Transmission fluid requirements are
indicated on the dipstick or on the dipstick handle.
Refer to your ªService Guideº to determine the
correct service interval.
