2001 SAAB 9-5 engine coolant

186 Starting and drivingParking on a hillWhen parking on a steep hill, turn the front
wheels so that they will be blocked by the
curb if the car should move. Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, luggage compartment
lid and doors, and lubricate them with
glycerol (glycerin).
 After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times.
 Fill the fuel tank with fuel to prevent con-
densation forming in it.
 Top up the coolant and check the anti-
freeze before the onset of winter.
 Park the car in a dry, covered and
well-ventilated building. Leave the park-
ing brake OFF!
 Disconnect the negative (-) battery lead.
If frost is likely to occur during the
long-term parking, remove the battery
and store it away from the frost.
 Ideally, the car should be put up on
blocks, with the wheels off the ground. If
this is not possible, inflate the tires to
about 43 psi (300 kPa).  Leave all the windows open a crack and
cover the car with a fabric tar paulin - not
one made of plastic.

191 Car care and technical information
Engine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label affixed to the left front inner
fender.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
• Sequential multiport fuel injection system.
 Three way catalytic converter.
 Crankcase emissions control system.
 Evaporative emission control system.
 On-Board diagnostic (OBD II) system.
Emission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.Saab Trionic engine management
systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure.
 Intake air temperature.
 Crankshaft position.
 Engine coolant temperature.
 Throttle position and
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
NOTEThe Trionic engine management systems
continuously monitors the operation of
these systems and have on-board diag-
nostic capabilities (OBD II).
If the ”Engine malfunction (CHECK
ENGINE)” lamp in the main instru-
ment illuminates, this indicates that the
Trionic ECM has detected a problem. The
car will continue to operate, but perfor-
mance may be diminished. You should
have your car checked by a Saab dealer
as soon as possible.

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.

236 Car care and technical information4Inspect the undercoating and touch
up if necessary. Pay particular atten-
tion to the fenders and wheel housings,
which are exposed to abrasion by flying
gravel, etc. If the composition has worn
or flaked off, the steel must be thor-
oughly cleaned and dried before a fresh
coat is applied. The cleaning is best
done with a scraper and a steel wire
brush, followed by washing with solvent.
Apply the new coating thinly, as other-
wise it may run off or fall off when dry.
For long tripsBefore setting off on a long journey, it is
advisable to have your car checked over by
your Saab dealer.
Obtain a few important items to take along
on your journey such as spare bulbs, wiper
blades, fuses, a Poly-V-belt and the like.
You can check some points yourself before-
hand:
 Make sure that the engine is in good con-
dition.
 Check that no oil or gasoline leaks out of
the engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the Poly-V-belt and replace it if it
shows any signs of hard wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
the jack in the car.
Recovery and/or
recycling of automotive
materialsA typical car consists of metals (65–75%),
plastics (10–14%), rubber (5%) and small
quantities of glass, wood, paper and tex-
tiles.
Some of these materials can be recycled,
while others can be recovered in chemical
processes for reuse in new products or as a
source of energy.
While the Saab 9-5 was still at the draw-
ing-board stage, Saab engineers were
giving serious consideration to how the
maximum quantity of materials could be
reclaimed from the car on its eventual
scrapping. To facilitate sorting, plastic parts,
for instance, have been marked to identify
the precise nature of the plastic.
Approximately 90% of the materials in the
car can be recycled or recovered, where
facilities exist.
Before the car is scrapped, all the oils and
other fluids that could pollute the environ-
ment should be recovered from the car. It
may be of interest in this context to learn that
the refrigerant used in the Saab 9-5’s ACC
systems (R134a) contains neither CFCs nor
any other chlorine compounds.
