Drive beltThe alternator is situated on the right-hand
side of the engine. It is driven via a
poly-V-belt from the crankshaft pulley.
The poly-V-belt also drives the water pump,
the A/C compressor and the steering servo
pump.
The belt tension is critical, and is adjusted
by an automatic belt tensioner.
See also page 55, "Warning charging".
Wipers and washersWiper bladesCheck and clean all wiper blades regularly.
We recommend Saab washer fluid for
cleaning.
If poor wiper performance is experienced,
clean the windshield with Saab washer fluid.
This is particularly important if the car has
been through an automatic car wash, as this
sometimes leave a wax coating on the wind-
shield.
If wiper performance is still unsatisfactory,
fit new blades.
Windshield and rear window1 Push the catch in (1).
2 Pull the complete wiper blade down-
wards so that it comes away from the
wiper arm. Slide the entire blade out
from the arm.
WARNING
Keep hands and clothing clear of drive
belts when engine is running.
Always stop the engine before
inspecting drive belts.NOTESerious damage can occur to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

Air conditioning
(A/C system)
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 in operation, mois-
ture from the air will condense on the evap-
orator. When the car is then parked, this
condensation will drip off the evaporator
and form a small pool of water on the
ground. This is normal. The warmer the
ambient air and the higher the humidity, the
greater the amount of condensation formed.Inadequate cooling:
a Make sure that the temperature and
air-distribution controls are in the
appropriate settings, see page 77.
b Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
c Make sure that the drive belt for the com-
pressor is not slipping, see page 179.
d Check the fuses for the ventilation fans
and compressor, see page 189.
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 refrigerant gas can cause
blindness or other injury.
