56 Instruments and controlsCheck fuse 15 (radiator fan) in the fuse
panel under the hood, see page 219.
If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level by looking at the
level visible through the plastic tank - do not
remove the cap.
If the coolant level falls below the MIN mark,
the SID will display the message ”FILL
COOLANT FLUID”.
Pressure gaugeThe turbo gauge indicates the air volume for
combustion, which is equivalent to the
engine load.
At low loads, the needle will move within the
white zone. At higher loads and during
heavy acceleration, the needle will enter the
yellow area. At very high loads (certain var-
iants only) the needle may enter the first part
of the red zone without indicating that there
is a fault.Under certain barometric conditions the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power, because the monitoring system is
holding the charging pressure down, you
should contact an authorized Saab dealer.
If the speed exceeds 143 mph (230 km/h),
the increase in speed will be limited by the
lowering of the boost pressure. The pres-
sure gauge then moves towards the middle
of the orange zone, indicating reduced
engine output and thus reduces the speed
of the car as well.
NOTEIf the needle, despite the above action,
enters the red zone, stop the car immedi-
ately, let the engine idle.
If the needle stays in the red zone, stop
the engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cool-
ing-system can cause hot coolant and
steam to be released.

196 Car care and technical informationCoolant The expansion tank is transparent to facili-
tate checking of the coolant level.
When the engine is cold, the coolant must
not lie over the KALT/COLD mark on the
expansion tank.
If the message ”FILL COOLANT FLUID” is
displayed on the SID, check the level of fluid
in the expansion tank.
Top up, as necessary, with equal parts of
clean water and Saab-approved coolant.
If the expansion tank is empty when coolant
is added, run the engine to normal temper-
ature and top up again, as necessary.
Coolant The cooling system is charged at the factory
with coolant containing a 50% concentra-
tion of a combined antifreeze and corrosion
inhibitor. A weaker mixture will result in
reduced anticorrosion protection. For pro-
tection against freezing in very cold
weather, a stronger concentration will be
needed.
A 60% concentration of antifreeze will pro-
vide protection at temperatures down to
-58 F (-50°C).The corrosion-inhibiting properties of the
coolant deteriorate over time, but
Saab-approved coolant can be used for
year-round protection. Change the coolant
as specified in the service program and use
only Saab-approved coolant – other makes
may need changing more frequently and
may damage the system.

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.
Loosen the cap carefully, and let the
engine cool before removing the cap.
 The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released.
NOTEAlways mix the antifreeze with the
appropriate volume of water before
adding it to the cooling system.
If pure 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
thermostat has opened to allow full
circulation.

197 Car care and technical information
Changing the coolant (Usually carried out as part of the Saab orig-
inal service by an authorized Saab dealer)
1 If the engine is hot, open the expan-
sion-tank filler cap carefully to release
the pressure, but do not remove it com-
pletely. Place a suitable receptacle
under the radiator and undo the drain-
cock.
2 Remove the filler cap on the expansion
tank.
3 The system takes about two minutes to
drain. Close the draincock.
4 Mix the antifreeze and water to the
required strength in a suitable container.
Use only Saab-approved coolant.
5 Add the coolant slowly to the expansion
tank. This will take about two minutes,
as the air needs time to escape.
6 Screw on the filler cap and fully tighten
the drain cook. Run the engine to normal
temperature. Top up the coolant, as nec-
essary, until the level is just below the
MAX mark on the tank.
7 Check the coolant again after a few days
and top up as necessary.

Fault diagnosis If 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 by an authorized Saab
dealer.
Important!
When the A/C system is running, the intake
air is dehumidified, and the resultant con-
densation is drained off through two outlets
underneath the floor of the car in the vicinity
of the front doors. It is therefore perfectly
normal for water to be seen dripping from
these outlets when the car is parked. The
warmer the ambient air and the higher the
humidity, the greater will be the amount of
condensation formed.
Inadequate cooling:
a Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
b Make sure that the drive belt for the com-
pressor is not slipping.
c Check the fuses for the ventilation fans
and compressor.
Maintenance  The drive belt for the compressor should
be inspected under the regular service
program.
 Clean dirt and insects away from the con-
denser and radiator to prevent clogging.
When washing the car, use the hose to
spray the radiator and condenser (located
forward of the radiator) from both sides
(both from the front of the car and from
inside the engine bay). Do not use a pres-
sure washer.
Caution: Do not use the hose when the
engine is hot.
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
Note: The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F).
NOTE The A/C system is designed for use
with R134a refrigerant.
 Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
 All repairs and adjustments on the A/C
system must be carried out by a Saab
dealer authorized for this kind of work.
 Never mix R134a and R12 refriger-
ants.
WARNING
 The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
 Escaping gas can cause blindness or
other injury.
