186 Car care and technical informationEngineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cams-
hafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration to a minimum.
The balance shafts are chain driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the coun-
ter-rotating shafts counteract the vibration
from the moving parts of the engine.
The transmission, located on the right (vie-
wed from the front), is integrated with the
engine. All models have front-wheel drive.
Engine oilChecking the oil level Check the engine-oil level regularly. This
should be done after the engine has been
run to normal temperature and then allowed
to cool for 2–5 minutes, with the car stan-
ding on level ground. Remove the dipstick
and wipe it clean before checking the level.
The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recommen-
ded grade via the dipstick tube.

187 Car care and technical information
Changing engine oil
The engine oil must be changed in accor-
dance with the service program, see
page 246.
Oil volume and grade, see page 255.
Oil changing should be carried out on a
warm engine.
1 Unscrew the drain plug in the bottom of
the sump and leave the oil to drain into
an oil tray or other suitable receptacle for
at least ten minutes. Take care, as the oil
may be hot.
2 After the oil has been drained, unscrew
and remove the oil filter.
3 Fit a new filter and tighten it by hand.
4 Refit the drain plug with a new washer.
5 Fill with new engine oil.
Run the engine to normal temperature and
check the oil level.
Change of engine oil and oil filter may be
required more frequently, see page 246.
WARNING
Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders. Avoid prolonged
skin contact whenever possible.
Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin by
washing thoroughly with soap and
water.
Keep oil out of reach of children.
Do not touch the turbocharger or
exhaust manifold. These get very hot
when the engine has been running.
Do not spill oil on hot parts of the
engine as this could cause a fire. Used
engine oil is particularly flammable.
Protect the environment. Do not
dispose of oil in the ground or down a
drain. Dispose of all used oil and oil
filters at an appropriate disposal facil-
ity.

191 Car care and technical information
Power steering fluidCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point forward during the
check.
Clean around the cap before it is unscre-
wed. Clean the dipstick. Screw in the cap
completely again before checking the level.
The oil should lie between the MAX and MIN
marks when the oil temperature is about
70°F (+20°C). If the oil is colder the level can
be lower, and in higher temperatures the
level can be higher, both of which are
acceptable.

WARNING
Do not fill the power steering fluid to
above the MAX mark. Too much fluid
can result in leakage.
Power steering fluid on hot engine
components constitutes a fire risk.
WARNING
For Service and Repair, parts equiva-
lent to those used by Saab should be
used.
Be aware that some non standard
replacement parts may put you in an
unsafe condition, even if they might fit.
