1997 CADILLAC ELDORADO cooling

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.
Heater and radiatoi hoses, and.other engine
parts, can be very hot. Don’t touch them. If you
do, you can be burned.
.Don’t run sthe engine if-there is a leak. If you
the engine,.+it could loge all coolant. That could
cause an engine fire, and sou could be burned.
Get any leak Pled 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.

Downloaded from www.Manualslib.com manuals search engine 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
1 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 coo% 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.

In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
You can be burned if yoa 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.

indicator.
A CHANGE TRANS FLUID message will
display on
the Driver Information Center (DIC) when
the powertrain computer determines that the transaxle
fluid needs to be changed or at each
100,080 miles
(160 080 km) interval, whichever occurs first. See your
Maintenance Schedule booklet for more information.
When this message appears, change the transaxle fluid
and reset the transaxle fluid life indicator as follows:
I. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on the
climate control at the same time until the
TRANS
FLUID RESET message appears on the DHC.
The cooling s stern in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL‘ extended life coolant.

The following explains your cooling system and how to
add coolant when
it is low. If YOU have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
@ Give freezing protection down to -34” F (-37°C).
Give boiling protection up to 265 OF (1 29°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
When adding coolant, it is important that you use
only DEX-COOL~ (silicate-free) coolant.
If coolant other than DEX-COOL@is added t~
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant
will require change SOQWW 0- at
34b,8(Bo miles (50 000 km) or 24 months,
whichever CD~CUP’S first. Damage caused
of coolant other than
covered
by your new vehicle warranty.

Downloaded from www.Manualslib.com manuals search engine Use a mixture of one-half clean water (preferably
distilled) and
one-half DEX-COOL@ coolant which
won’t damage aluminum
parts. If you use this mixture,
you
don’t need to add anything else.
A, CAUTION.: ..
Adding only plain water to your cooling system
can
be dangerous. Plain water, or some other
liquid Bike alcohol, can boil before the proper
coolant mix will.
YQW 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 5W50 mix of clean
water and
DEX-COOE~ coolant.
If YSU use an improper coolant mix, your engine
could overheat and
be badly damaged. The
repair cost wouldn’t be covered by your
warranty. Too much water in the mix can freeze
and crack the engine, radiator, heater core and
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
If you use the proper coolant, you don’t have to
add extra inhibitors
QF additives which claim to
improve the system. These can be harmful.

Downloaded from www.Manualslib.com manuals search engine The surge tank is located next to the engine block on the
passenger's side
of the engine.
The cooling system is under a lot
of pressure when it is
hot. If the CHECK COOLANT LEVEL message
appears on the
DIC, you will need to add coolant.
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never
turn the surge tank pressure cap =- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the full cold mark,
which is 2.5 inches (6.4 cm) below
the base
of the fill neck. Use a flashlight as necessary to
see into the
tank.
