2002 SAAB 9-3 coolant

184 Starting and drivingDriving considerations
with compact spare
wheel/tire fitted The following should be observed when the
compact spare wheel (T115/70 R16) is
installed:
The compact spare is light and easy to
handle when changing the wheel. Do not
drive farther than necessary with the com-
pact spare fitted – the maximum life of the
wheel is only just over 2000 miles
(3,500 km). Have the standard wheel
repaired and reinstalled as soon as possi-
ble.Points to bear in mind when driving with a
compact spare wheel:
 The car’s ground clearance is reduced
with the compact spare fitted.
 Only one compact spare wheel may be
used at any time.
 Take care not to hit the curb.
 Do not fit snow chains.
 Leave the wheel cover off, so that the
warning text is readily visible.
For long tripsBefore starting off on a long journey, it is
advisable to have your car inspected 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 fuel 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 wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
 Take an extra car key/remote control and
keep it separate, see also page 36.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
the jack in the car.
WARNING
Do not exceed 50 mph (80 km/h) as the
tire can overheat and adversely affect the
handling of the car.
The tire should be inflated to 60 psi
(420 kPa).
NOTETo avoid damaging a punctured alloy
wheel this can be placed outside up in the
spare-wheel well but only while driving to
the closest dealer.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 142.

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.
 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.
ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refueling will
be recovered by the car and not released
into the atmosphere. The hydrocarbons are
absorbed in an evaporative emission canis-
ter. When the engine is subsequently
started, the evaporative emission canister is
gradually purged as air is sucked into it
through a shut-off valve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. "Refueling", see page
151.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate and a TIGHTEN FUEL FILLER CAP
message to appear on SID.
NOTEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the CHECK
ENGINE light in the main instrument illu-
minates, the Trionic ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a Saab
dealer as soon as possible.

(80°C). This can be achieved by driving
the car for about 30 min on the open
road.
2 With the engine idling, move the selector
lever to D and wait for at least
15 seconds. Next, move the selector
lever to R and wait for 15 seconds again.
Finally, move the selector lever to P. Let
the engine idle.
3 Wipe the dipstick clean with a lint-free
cloth and put it back.
4 With the fluid at normal temperature, the
level should be between the MAX and
MIN marks on the dipstick. Top up, as
necessary, with Texaco Texamatic Dex-
tron III automatic-transmission fluid,
adding it through the dipstick pipe. The
distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 0.4 qts
(0.4 litre).
If the outside temperature is below 50°F
(10°C), the fluid will not reach the specified
temperature of 175°F (80°C). In this case,
the correct fluid level may be 0.8 in (20 mm)
below the MAX mark.
CoolantThe expansion tank is transparent, to facili-
tate checking. The level must be a little
under the mark ”KALT – COLD” on the tank
when the engine is cold. If the SID message
"FILL COOLANT FLUID" is displayed, the
level in the expansion tank should be
checked. Top up as necessary with equal
parts of clean water and coolant. Use only
coolant approved by Saab.
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 filled 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).
NOTEIf there is a burnt smell or the fluid is black,
change the fluid as soon as possible.
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.
 Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.

193 Car care
The coolant does not normally have to be
changed during the service life of the car.
This type of coolant has a reddish colour
and should not be mixed with other types of
coolant. Saab Original coolant should be
used all year round. Only use coolant
approved by Saab.
Air filter
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.
WARNING
Only use an air filter recommended by
Saab Automobile AB.

Oil recommendation: We recommend the use of oils that are available from your
Saab dealer, for regular oil changes. These oils fulfill the most
stringent requirements set by API and ACEA classifications.
Basic recommendations for Saab engines
 SAE 5W-30 or 0W-30, 5W-40.
The oil should be semi or fully synthetic and fulfill grade re-
quirements for ACEA A3/B3, API SJ or higher. In addition to API
and ACEA the ILSAC GF-3 specification is approved for use in
applicable markets.
Fully synthetic oils with viscosity’s 0W-40/50 of well known
brands and fulfilling minimum ACEA A3/B3 are also recom-
mended, especially for extreme driving conditions.
