There is an overpressure in the cooling
system. Coolant temperatures can some-
times exceed 212° F (100° C).
If the coolant level drops too low, the follow-
ing message appears on the SID:
The properties of the coolant are retained
for the entire service life of the car. There-
fore, it is not necessary to change the cool-
ant.
The coolant contains 45 % antifreeze and
anti-corrosion fluid. This ratio gives the best
cooling effect. Lower concentrations should
be avoided, in view of the corrosion risk.
Coolants of a different brand could damage
the engine or cooling system. We therefore
recommend strict use of coolants that have
been approved by Saab.Note
If incorrect coolant is used or added, the
life-time properties will be affected. Even if
the coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.
WARNING
Proceed with caution if the radiator is
boiling when you open the hood.
Never remove the expansion-tank
filler cap when the radiator is boiling.
The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released. These
can cause injury to your eyes and
burns. Loosen the cap carefully, and
let the engine cool before removing
the cap.
Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
Coolant level low.
Refill.
NOTEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted antifreeze is added, the
engine could still freeze and be damaged.
This is because the antifreeze will not mix
properly with the coolant before the ther-
mostat has opened to allow full circula-
tion.

274 Car careAir conditioning (A/C)
TroubleshootingIf a fault occurs in the A/C system, there are
a number of checks you can perform your-
self. If the fault persists, however, have the
system checked at a workshop. We recom-
mend that you contact a Saab dealer.
Note
When the A/C system is running, the intake
air is dehumidified. The resultant condensa-
tion that forms on the evaporator is drained
off under the car. When the car is parked,
this may result in a small puddle forming on
the ground. The warmer the air and the
higher the relative humidity, the more con-
densation will be produced.Inadequate coolinga Check that the condenser (in front of the
radiator) has not become clogged with
dirt and insects.
b Make sure that the compressor drive
belt does not slip (see page 219).
c Check the fuses for the ventilation fans
and compressor (see page 239).
MaintenanceThe compressor drive belt should be
inspected under the regular service
program.
Clean away dirt and insects from the
condenser and radiator to prevent clog-
ging. When washing the car, use the hose
to spray the radiator and condenser
(located in front of the radiator) from both
sides (both from the front of the car and
from inside the engine bay). Do not use a
pressure washer.
Caution: Do not hose down the radia-
tor and condenser while the engine is
hot.
WARNING
All repairs and adjustments to the A/C
system must be carried out at a Saab
dealer authorized for this kind of work.
The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
Escaping gas can cause eye injury or
other personal injury.NOTEThe A/C system is designed for use
with R134a refrigerant.
Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
Never mix R 134a with other refriger-
ants.
NOTEDo not use a pressure washer when
cleaning the condenser or radiator due to
the risk of damage.

275 Car care
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor uses a lubricant that circu-
lates with the coolant.
Note
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cut in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be
re-aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure.To check the aim, the vehicle should be
properly prepared as follows:
The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
The vehicle should be placed so it is
perpendicular to the wall or other flat
surface.
The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.
The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
The vehicle should not have any snow, ice
or mud attached to it.
Tires should be inflated to the prescribed
pressure.
Close all doors.
Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
WARNING
Before checking/adjusting the headlight
aiming, switch off the engine to avoid
danger of fingers and hands being injured
by moving parts.
The radiator fan can start up even when
the engine is switched off.NOTETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.
