196 Car care and technical information
Coolant
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.
NOTE
Always 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.
