195Car care and technical information
Transmission fluid
Manual transmission
Check and top up the fluid in accordance
with the service program.
Automatic transmission
Check and top up the fluid in accordance
with the service program.
Coolant
There is an overpressure in the cooling sys-
tem. Coolant temperatures can sometimes
exceed 212°F (100 °C).
The expansion tank is transparent to facili-
tate checking of the coolant level.
When the engine is cold, the coolant shall lie
on or just above the KALT/COLD mark on
the expansion tank.
If the message
”Coolant level low.
Refill.”
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.
Coolants of a different brand could damage
the engine or cooling system. We therefore
recommend strict use of coolants that have
been 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.
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.
• The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released. These
can cause injury to your eyes and
burns. Loosen the cap carefully, and
let the engine cool before removing
the cap.
• Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
