"Recommended grade and viscosity
under severe driving conditionsIf the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.API classification SL (or SJ):
SAE viscosity no.: 30, 40, 10W-50, 20W-40, 20W-50
"Synthetic oilYou can use synthetic engine oil that meets the same
requirements given for conventional engine oil. When
using synthetic oil, you must use oil of the same clas-
sification, viscosity and grade shown in this owner’s
manual, and must follow the oil and filter changing in-
tervals shown in the maintenance schedule.
Cooling systemNever attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is re-moved.!The cooling system has been filled at the fac-
tory 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% eth-
ylene-glycol basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix dif-
ferent kinds of coolant.

ed parts. The alcohol contained in the enginecoolant may damage the paint surface."Cooling fan, hose and connectionsYour 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 temperature gauge exceeds the
normal operating range, the cooling fan circuit may be
defective. 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 necessary, there may
be a leak in the engine cooling system. It is recom-
mended that the cooling system and connections be
checked for leaks, damage, or looseness.
"Engine coolant!Checking the coolant level1) “FULL” level mark
2) “LOW” level markCheck the coolant level at each fuel stop.
1. Check the coolant level on the outside of the reser-
voir while the engine is cool.
2. If the level is close to or lower than the “LOW” level
mark, add coolant up to the “FULL” level mark. If the
reserve tank is empty, remove the radiator cap and re-
fill as required.
