CADILLAC SEVILLE 1997 4.G Owners Manual

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.

If you haven’t found a problem yet, but the coolant level
isn’t at the proper level
(2.5 inches (6.4 cm) below the
base
of the fill neck), add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL“ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap,
is cool
before
you do it. (See “Engine Coolant” in the Index for
more information.)

Steam and scalding liquids from a hot cooling
system
can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
out at high
speed. Never turn the cap when the
cooling system, including the coolant surge
tank
pressure cap, is hot. Wait for the cooling system
and coolant surge
tank pressure cap to cool if you
ever have to turn the pressure cap.

Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong
mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and DEX-COOL@coolant.

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other
parts. So
use the recommended coolant.
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant
on a hot engine.
1. You can remove the coolant surge tank pressure cap
when
the cooling system, including the coolant surge
tank pressure cap and upper radiator hose,
is no
longer hot. Turn the pressure cap slowly
counterclockwise until it first stops. (Don't press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.

2. Then keep turning the cap, but now push down as
you turn it. Remove the pressure cap.
3. Then fill the coolant surge tank with the proper mix,
up to the base of the filler neck.

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.

Downloaded from www.Manualslib.com manuals search engine It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out
of a tire, it’s much more likely to leak out slowly.
But if you should ever have
a “blowout,” here are a few
tips about what to expect and what to do:
If
a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and
grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve. acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get
the vehicle under control by
steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake
to a stop -- well off the road if possible.
If a tire goes flat, the
next part shows how to use your
jacking equipment
to change a flat tire safely.
If a tire goes flat. avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
I A CAUTION:
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Put the shift lever in PARK (P).
2. Set the parking brake firmly.
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks
at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle,
at the opposite end.

The following steps will tell you how to use the jack and
change a tire.

The equipment you’ll need is in the trunk. Pull the
carpeting from the
floor of the trunk. Turn the retainer
(center dial) on the compact spare cover
counterclockwise to remove it. Lift and remove the
cover. (See “Compact Spare
Tire” later in this section
for
more information about the compact spare.)

The tools you’ll be using include the jack (A) and the
wheel wrench
(B).
There is a center wheel cover on the aluminum wheel.
Using the flat end
of the wheel wrench, gently pry the
wheel cover
off. Be careful not to scratch the aluminum
wheel edge and don’t try
to remove it with your hands.
