engine FORD TAURUS 1998 3.G Repair Manual

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.
Maintenance and care
162

After washing, apply the brakes several times to dry
them.
Waxing your vehicle
Wax when water stops beading on the surface. This
could be every three or four months, depending on
operating conditions.
Use only carnauba or synthetic-based waxes. Use
cleaning fluid or alcohol with a clean cloth to remove
any bugs and tar before waxing vehicle. Use tar
remover to remove any tar spots.
Avoid getting wax on the windshield. If you have
wax applied at a commercial car wash, it is
recommended that you clean the wiper blades and
windshield as described inCleaning the wiper
blades and windshield.
Repairing paint chips
Minor scratches or paint damage from road debris
may be repaired with touch-up paint, repair foil or
aerosol paint spray from the Ford accessory line.
Observe the application instructions on the
products.
Remove particles such as bird droppings, tree sap,
insect remains, tar spots, road salt and industrial
fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your
vehicle. Do not use acid-based or alcohol-based
wheel cleaners, steel wool, fuel or strong detergents.
Never use abrasives that will damage the finish of
special wheel surfaces. Use a tar remover to remove
grease and tar.
Cleaning the engine
Engines are more efficient when they are clean
because grease and dirt buildup keep the engine
warmer than normal. When washing:
Maintenance and care

²Take care when using a power washer to clean
the engine. The high pressure fluid could
penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking
the engine block or other engine components.
²Cover the highlighted areas to prevent water
damage when cleaning the engine.

²3.0L Duratec engine
²3.4L SHO engine
²Never wash or rinse the engine while it is
running; water in the running engine may cause
internal damage.
Cleaning the engine
Cover the underhood electrical connections and
terminals of your vehicle when cleaning the engine
compartment. Avoid spraying or splashing cleaning
solvents or detergent solutions on the terminals and
connections. After the cleaning is completed and
with the engine not running, remove the protective
cleaning coverings. Exposing electrical connections
and terminals to cleaning solvents and detergent
solutions over a period of time can corrode them
and result in electrical system damage and
malfunctions.
Cleaning plastic exterior parts
Use vinyl cleaner for routine cleaning. Clean with a
tar remover if necessary. Do not clean plastic parts
with thinners, solvents or petroleum-based cleaners.
