Saab 2006 9-2 - Manual (Page 250)

11-12
Maintenance and service
eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM (or SL):
SAE viscosity no.: 30, 40, 10W-50,
20W-40, 20W-50
¢ Synthetic oil
You can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this owner’s manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule.
Cooling system
¢ Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be de-
fective. Check the fuse and replace it if
necessary. If the fuse is not blown, have
the cooling system checked by your Saab
dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.
— The cooling system has been
filled at the factory with a high
quality, corrosion-inhibiting, year-
around coolant which provides
protection against freezing down
to –33 °F (–36°C). For adding, use
genuine Saab coolant or an equiv-
alent: a mixture of 50% soft water
and 50% ethylene-glycol basis
coolant. Use of improper coolants
may result in corrosion in the
cooling system. It is important to
maintain protection against freez-
ing and corrosion, even if freezing
temperatures are not expected.
Never mix different kinds of cool-
ant.
— Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
