Check that the jack has located properly
. against the flange on the sill beam and
that the whole of the base is firmly in
contact with the ground.
5 Jack up the car until the wheel is clear
of the ground, then remove the wheel
bolts and the wheel.
6 Mount the wheel and tighten the wheel
bolts loosely. Check that the wheel and
bolts are correctly positioned.
7 Lower the car. Tighten the wheel bolts
in the order shown in the illustration.
Tighten to 80-90 ft. Ibs. (105-125 Nm).
Never use an impact wrench for final
tightening of wheel bolts. Carefully ob­

damage.
The three-spoke asymmetric wheels fitted
to certain models are marked "L" for left and
"R" for right. These markings indicate the
side of the car the wheels should be
mounted on in order to maintain a consis­
tent appearance. There is no risk for re­
duced brake cooling or wheel balance if the
wheels are mounted contrary to the mark­
ings.
Air conditioning
Fault diagnosis
If the air conditioning system is malfunction­
ing, check the following items yourself. If
these checks fail to reveal the cause of the
problem, contact an authorized Saab
dealer.
NOTE!
When the air conditioning system is run­
ning, condensation will form on the evap­
orator. WhEm the car is parked, this con­
densation may drain off and form
a
small
pool of water under the car.
Inadequate cooling
1 Check that the temperature control and
the air distribution control are correctly
set.
2 Check that the condenser (located in
front of the radiator) has not become
clogged by dirt or insects.
3 Check that the drive belt for the com­
pressor is not loose, damaged or worn.
