cooling CADILLAC ELDORADO 1996 10.G User Guide

Downloaded from www.Manualslib.com manuals search engine 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 seem 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.
How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the proper level
(2.5 inches (60 mm) below the
base
of the fill neck), add a 50/50 mixture of cleun
water (preferably distilled) and DEX-COOL TM
antifreeze 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.

Downloaded from www.Manualslib.com manuals search engine 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 TM antifreeze.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
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 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.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
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 the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
“Service and Owner Publications” in the Index.)

NOTICE:
If you 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
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

Downloaded from www.Manualslib.com manuals search engine Checking Coolant
The surge tank is located next to the engine block on the
passenger’s side of the engine.
The cooling system when hot is under
a lot of pressure.
If the CHECK COOLANT LEVEL message appears on
the
DIC, you will need to add coolant.
A CAUTION:
I
I
lhrning 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 (60 mm) below
the base
of the fill neck. Use a flashlight as necessary to
see into the tank..

Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control.
You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts for
replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance and tire or tire chain clearance to
the body and chassis.
See “Changing a Flat Tire” in the Index for more
information.
Used Replacement Wheels
-
CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how many miles it’s been driven. It could fail
suddenly and cause an accident.
If you have to
replace a wheel, use
a new GM original
equipment wheel.
