2002 SAAB 9-5 coolant temperature

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 coolant does not normally have to be
changed during the service life of the car.
The type of coolant used has a reddish color
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.

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.
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.
