1997 CADILLAC SEVILLE check engine

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center.
If it is, you may have a leak in the
radiator hoses, heater hoses, radiator, water
pump or
somewhere else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them. If
you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could
lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

4. With the coolant surge tank pressure cap off, start
the engine and let it run
until you can feel the upper
radiator hose getting hot. Watch
out for the
engine fans.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches about 2.5 inches (6.4 cm)
below the
bass of the filler neck.
5. Then replace the pressure cap. Be sure the arrows on
the pressure cap line up like this.
Start the engine
and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear
on the
Driver Information Center. coolant
is at the proper fill
level.
If a CHECK COOL.ANT LEVEL message does
appear. repeat Steps 1 through 3 or see your dealer.

the compact spare tire with
a full-size tire as soon as you
can. See the storage instructions label to replace your
compact spars into your trunk properly.
RETAINER
SPARE TIRE
WHEEL WRENCH
Although the compact spare tire was fully inflated
when your vehicle was new.
it can lose air after a time.
Check the inflation pressure regularly.
It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire
is correctly inflated. The compact
spare is made
to perform well at speeds up to 65 mph
(1 05 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where
you want. Of course, it’s
best
to replace your spare with a full-size tire as soon
as you can. Your spar!: will last longer and be in good
shape in case you need it again.
NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic car wash with guide rails.
The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.

Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Cadillac dealer before adding equipment
to the
outside
of your vehicle.
Use premium unleaded gasoline rated at 91 octane
or higher. At a minimum,
it should meet specifications
ASTM D48 14 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting
the AAMA
specification could provide improved driveability
and emission control system protection compared to
other gasolines.
Be sure the posted octane for premium
is at least 91.
If the octane is less than 9 1, you may get a heavy
knocking noise when
you drive. (In an emergency. you
may be able
to use a lower octane -- as low as 87 -- if
heavy knocking does not occur.) If you’re using
91 or
higher octane unleaded gasoline and
you hear heavy
knocking, your engine needs service. If
your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate
on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily
on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn
on and/or your vehicle
may fail
a smog-check test. If this occurs, return to your
authorized Cadillac dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause
of the condition is the type of fuels used. repairs
may not be covered by your wan-anty.
Some gasolines that are
not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT):
ask your service station operator whether or not this fuel
contains MMT. General Motors does not recommend the
use of such gasolines. If fuels containing MMT are used.
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may
turn on. If this occurs, return to your authorized
Cadillac dealer for service.

Downloaded from www.Manualslib.com manuals search engine To provide cleaner air, all gasolines in the United States
are now required
to contain additives that will help
prevent deposits
from forming in your engine and
fuel system, allowing your emission control system to
function properly. Therefore,
you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available
in your area to
help clean the air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use
it. It can corrode
metal parts in your
fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
If you plan on driving in another country outside the
United States or Canada, the proper fueI may be hard
to
find. Never use leaded gasoline or any other fuel not
recommended
in the previous text on fuel. Costly repairs
caused by use
of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club. or
contact
a major oil company that does business in the
country where
you‘ll be driving.
You can also write
us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

If you have the Driver Information Center (DIC), a
CHECK OIL LEVEL message will appear when the
engine
oil is approximately 1 quart (1 L) low. If the
message is displayed. check the dipstick level and add
oil
as needed.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick
is
located behind the radiator
on the driver’s side of the
engine. The black handle
says
ENGINE OIL on it.
Turn off
the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again.
keeping the
tip down, and check the level.
FVl.lCl1 $: If the oil is at or below the ADD line, then you'll
need to add at least one quart of oil. But you must use
the right kind. This part explains what kind of
oil to use.
For crankcase capacity, see "Capacities and
Specifications" in the Index.
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark
that shows the proper operating range,
your engine could be damaged.
Thi: oil fill cap is located
behind the radiator on the
passenger's side
of the
engine.
Turn the cap
counterclockwise to remove
it.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back
in when you're through.
