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

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.

If you get the overheat warning but see or hear no steam, the problem
may not be
too serious. Sometimes the engine can get a little too hot
when you:
0 Climb a long hili on a hot day.
0 Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute
or
so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting and open the
window,
as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to
the highest gear wh.ile driving
-- AUTOMATIC OVERDRIVE (@) or
THIRD (3).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about
10 minutes. If the warning doesn’t come back on,
you
can drive normally.
If the warning continues,
pull over, stop, and park your vehicle right away.
If there’s
still no sign of steam, you can idle the engine for two or three
minutes while you’re parked,
to see if the warning stops. But then, if you
still have the warning, turn off the engine and get everyone out of the vehicle
until it cools down. Also, See “Overheated Engine Protection Operating
Mode’’ listed previously
in this section.

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.

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.
