1995 CADILLAC ELDORADO Engine Cooling system

Downloaded from www.Manualslib.com manuals search engine If the coolant inside the coolant surge tank is boiling, don’t do anything
else until
it cools down.
A CAUTION
The coolant level
should be visible
inside
the surge tank
once the cap
has been
removed.
If it isn’t,
you may have a leak
in the radiator hoses,
heater
hoses, radiator,
water pump or
somewhere
else in the
cooling system.
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.
I 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.

A CAUTION:
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
a proper antifreeze.
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.

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 to the left 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.

ENGINE 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.
The proper coolant for your Cadillac
will:
Give freezing protection down to -34’F (-37OC).
0 Give boiling protection up to 262’F (128OC).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets
“GM Specification 1825M,” which won’t damage
aluminum parts. You can also use
a recycled coolant conforming to GM
Specification 1825M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant flush and
refill. If you use this
mixture, you don’t need to add anything else.

Downloaded from www.Manualslib.com manuals search engine If you use an improper coolant mix, your engine could overheat
and
be badly damaged. The repair cost wouldn't he covered by
your warranty. Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.
Adding Coolant
Your cooling system when hot is under a lot of pressure. If the ENGINE
COOLANT LOW message should appear on the Driver Information
Center,
you will need to add coolant.
If the ENGINE COOLANT LOW message does not appear, the coolant
is at the proper fill level.
