cooling OLDSMOBILE AURORA 1996 Owners Manual

Trunk Security Override
The Remote Lock Control transmitter will open the
trunk even if the override switch is
in the OFF position.
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can’t see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:
0 Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the setting
on on any airflow selection except RECIRC.
That
will force outside air into your vehicle.
See “Comfort Controls” in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
See “Engine Exhaust’’ in the Index.
Theft
Vehicle theft is big business, especially in some cities.
Although your Aurora has a number
of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
With the ignition
OFF and the driver’s door open, you’ll
hear a chime reminding you to remove your key from
the ignition and take it with you. Always do this.
Your
steering wheel will be locked, and so will your ignition
and transaxle. And remember to lock the doors.

Operating the RECIRC mode in cold temperatures or
under high humidity conditions may cause moisture to
form on the inside of the windshield. If this condition
occurs, deselect the RECIRC button.
A/C ON: Press this button to turn the air conditioning
on and off. If the system is operating in the automatic
mode, the A/C
ON indicator light will automatically
illuminate.
In the auto mode, the A/C compressor will
only operate when the system determines it is needed.
OFF: Rotate the AUTO-PUSH knob to the OFF
position. Turning the system off will cause the fan to
turn off and the airflow to be directed out the lower floor
outlets. The system will still try to keep the interior of
the vehicle at the previously chosen comfort setting. The
outside temperature will show in the display when the
system is
OFF.
Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all
modes unless the A/C
ON button is in the off position
(indicator light will not be illuminated). However, the
air conditioning compressor will not operate when the
outside temperature is below 44°F
(7 "C). When the
air conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off
to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot
air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level.
If the
system is in the automatic mode (AUTO-PUSH knob
indicator light
is on), during very hot days the system
will automatically
go to the RECIRC mode and the
temperature door will
be positioned at the full cold position
for maximum cooling. You can choose the extreme comfort setting of
60°F ( 16 " C), but the system will not cool any
faster by choosing the extreme comfort setting.

If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check alkfluid
levels and
also the brakes, tires., cooling system and
transaxle. These parts can work hard on mountain
roads.
Know how to go down hills. The most important
thing to know
is this: let your engine do some of the
slowing down.
Shift to a lower gear when you go
down a steep or long hill.
If you don't shift down, your brakes could get so
hot that they wouldn't work well. You would then
have poor braking or even none going down
a
hill. You could crash.. Shift down to let your
engine
assist your brakes on a steep downhill
slope.

do all the work of slowing down. They could get so
hot that they wouldn't work well. You would then
have poor braking
or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.
Know how to
go uphill. Shift down to THIRD (3).
This will help cool your engine and transaxle, and
you can climb the hill better.
In hilly terrain, you-may want to switch to the
POWER mode for better performance. '
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don't swing wide or cut
across the center of the road. Drive at.speeds that
let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing
zones, a falling rocks area or winding
roads.
Be alert to these and take appropriate action.

When You Are Ready to Leave After
Parking
on a Hill
1.
2.
3.
4.
Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
Let up on the brake pedal.
Drive slowly until the trailer
is clear of the chocks.
Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Surge Tank with Pressure Cap
B. Two Electric Engine Cooling Fans
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
ProCarManuals.com

The coolant level should be indicated by a CHECK
COOLANT
LEVEL message on the Driver Information
Center.
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.
A C,’ UT’O’‘:
~ 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 fan(s) are running. If the engine
is overheating, both fan(s) 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 FULL COLD, add a
50/50 mixture of clean
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.)
I
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.

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.
ProCarManuals.com

I 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 about
one-quarter
turn to the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
