Coolant CADILLAC ELDORADO 1995 10.G User Guide

Downloaded from www.Manualslib.com manuals search engine Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as:
Climbing gradcs steeper than 4% at ambient temperatures above
90" F (32" C) with a loaded vehicle and trailer.
0 Stopping after high-speed driving.
Idling for long periods in stop and go traffic.
If the
ENGINE HOT-A/C COMPRESSOR OFF message appears on the
Driver Information Center,
do not be alarmed. This is a normal function
designed to reduce the load
on the engine and cooling system. You can
continue to drive your vehicle.
If the ENGINE COOLANT HOT-IDLE ENGINE message appears on
the Driver Information Center, pull off to the side of the road as soon as
it
is safe to do so. When the vehicle is at a complete stop, shift the
transaxle selector
to PARK (P) and allow the engine to idle. Do not turn
off the engine
or increase engine speed above a normal idle. After several
minutes, resume driving at
a reduced speed. Return to normal driving
after
1.0 minutes if the ENGINE COOLANT HOT-IDLE ENGINE
message is not displayed.

The Driver Information Center will display either ENGINE COOLANT
HOT-IDLE ENGINE or
STOP ENGINE ENGINE OVERHEATING.
In addition you will find the warning light about a hot engine on your
instrument panel on Canadian vehicles.
Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message STOP ENGINE
ENGINE OVERHEATING is displayed, an overheat protection mode
which alternates firing groups of four cylinders helps prevent engine
damage. This operating
mode allows your vehicle to be driven to a safe
place
in an emergency; you may drive up to 50 miles (80 km). Towing a
trailer in the overheat protection mode should be avoided.
NOTICE:
After driving in the “Overheated Engine Protection Operating
Mode,” to avoid engine damage, allow the engine
to cool before
attempting any repair. The engine oil may be severely degraded.
Change the oil and reset the
oil life indicator. See “Engine Oil,
When
to Change” in the Index.

COOLING SYSTEM
When you decide it’s safe to lift the hood, here’s what you’ll see:
A. Coolant surge tank with pressure cap.
B. Electric engine fans.
5-15

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.

push down
as you
turn it. Remove
the pressure cap.

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
ievel reaches the base of the filler neck.

Start the engine and allow
it to warm up. If the ENGINE COOLANT
LOW message does not appear on the Driver Information Center,
coolant
is at the proper fill level. If an ENGINE COOLANT LOW

IF A TIRE GOES FLAT
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, 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.
