coolant level Oldsmobile Alero 2003 Owner's Manuals

4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts.
If you don’t, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
Your automatic transaxle
has a shift lever located
on the console between
the seats.
PARK (P): This position locks your front wheels. It’s the
best position to use when you start your engine
because your vehicle can’t move easily.
It igerous to get out of your vehicle if the
shift lever
is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to.
If you have left the
engine running, the vehicle can move
suddenly. You
or others could be injured. To
be sure your vehicle won’t move, even when
you’re on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). See “Shifting Into Park (P)” in the
Index. If you’re pulling a trailer, see “Towing a
Trailer”
in the Index.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle shift
lock control system. You have to apply your regular brake
before you can shift from PARK
(P) when the ignition key
is
in ON. If you cannot shift out of PARK (P), ease
pressure on the shift lever and push the shift lever all the
way into PARK (P) as you maintain brake application.

This gage shows the engine coolant
temperature.
if the gage
pointer moves into the red
area, the light comes
on and you hear a chime,
your engine
is too hot.
It means that your engine
coolant has overheated.
See
Engine Overheating on page 5-26.
Low Coolant Warning Light

This light comes on
briefly when you turn your
ignition on.
!f this !ight comes on and stays on and you hear a
chime, the coolant level in your vehicle is low.
See
Engine Coolant on page 5-23. If the light is on along
with an overheat warning, you may have a
serious overheating problem. See
Engine Coolant
Temperature Gage on page 3-31
listed previously.
Notice: Damage to your engine from neglected
coolant problems can be costly and is not covered
by your warranty.
See
Engine Overheating on page 5-26 for information
on what
to do. Your vehicle should be serviced as soon
as possible.

When to Check and What to Use
Schedule to determine
how often you should
check the fluid level in your
master cylinder reservoir
and for the proper
fluid. See
Part B: Owner
Checks and Services
on page 6-9 and Part D:
Recommended Fluids
and Lubricants
on
page 6- 15.
How to Check and Add Fluid
You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, take
the cap
off. If the fluid level reaches the top of the
reservoir, the fluid level is correct. It isn’t a good idea to
top
off your clutch fluid. Adding fluid won’t correct a
leak. A fluid loss in this system could indicate a problem
Have the system inspected and repaired.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL@ engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add
only DEX-COOL@ extended life 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 on
page 5-26.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (1 29°C).
@ Protect against rust and corrosion.
@ Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.

Checking Coolant
2.2L L4 ECOTEC Engine shown,
3400 V6 Engine similar
The coolant surge tank
is located in the engine
compartment on the passenger’s side of the vehicle.
See
Engine Compartment Overview on page 5-12
for more information on location. Turning
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.
The vehicle must be on
a level surface. When your
mgine is cold, the coolant level should be at the
FULL
;OLD mark, or a little higher.
If the
low coolant light
comes on and stays on,
it
means you’re low on
engine coolant.
See
Low Coolant Warning Light on page 3-31 for more
nformation.
5-25

An electric engine cooling 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. The vehicle
should be parked on a level surface.
The coolant level should be at or above the
FULL
COLD mark. If it isn’t, you may have a leak at the
pressure cap or in the radiator hoses, heater hoses,
radiator, water pump or somewhere else in the cooling
system.
5-29

Heater a _.__ . -ldiatoL -.oses, 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.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running.
If they aren’t, your vehicle needs service.
Notice: Engine damage from running your engine
without coolant isn’t covered by your warranty.
Notice: When adding coolant, it is important that
you use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL
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.
Damage caused by the use of coolant other
than DEX-COOL@ is not covered by your new vehicle
warranty.
How to Add Coolant to the Coolant
Surge Tank
Notice: This vehicle has a specific coolant fill
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
If you haven’t found a problem yet, check to see
if
coolant is visible in the surge tank. If coolant is visible
but the coolant level isn’t at or above the
FULL
COLD mark, add a 50/50 mixture of clean, drinkable
water
and DEX-COOL@ coolant 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 on page 5-23 for more
information.
5-30

1. Park the vehicle on a level surface.
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
one-half turns. If you hear a hiss, wait for that to
stop. This will allow any pressure still left
to
be vented out the discharge hose.

pressure cap slowly, and
remove
it.
5-33

3. Then fill the coolant surge tank with the proper
mixture, to the hash mark on the label. Wait
about five minutes, then check to see
if the level is
below the hash mark.
If the level is below the
hash mark, add additional coolant to bring the level
up to the hash mark. Repeat this procedure until
the level remains constant at the hash mark
for at least five minutes. 4.
With the coolant surge tank 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 cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the FULL COLD mark, add more of the proper
mixture to the coolant surge tank until the
level reaches the FULL COLD mark.
