Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan, or fans if you
have the
3800 V6 engine.
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else until it cools down. The coolant
level should be at or above
the
FULL HOT mark. If it isn’t, you
may have a leak in the radiator hoses,
heater hoses, radiator, water pump or
somewhere else in the cooling system.

Problems on the Road
1..
NOTICE:
Engine damage from running your
engine without coolant isn’t
covered by your warranty. If
there seems to be
no leak, check to
see if the electric engine fan is running.
If the engine is overheating, the fan
should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the
Coolant Recovery Tank
If you haven’t found a problem yet, but
the coolant level isn’t at or above the
FULL HOT mark, add a 50/50 mixture
of
clean water (preferably distilled) and
a proper antifreeze at the coolant
recovery tank. (See
Engine Coolant in
the
Index for more information about
the proper coolant mix.)
NOTICE:
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts. Use the
recommended coolant.
ProCarManuals.com

As shown in the chart, SAE 5W-30 is
best for your vehicle. However, you can
use SAE 1OW-30 if it’s going
to be 0°F
(-18°C) or above. These numbers on an
oil container show
its viscosity, or
thickness.
Do not use other viscosity oils,
such as SAE 1OW-40 or SAE 20W-50.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three things:
SH or SG
“SH’ or “SG’ must be on the oil container,
either by itself or combined with other
quality designations, such as “SHKD,”
“SH,SG,CD,” “SG/CD,” etc. These
letters show American Petroleum
Institute (API) levels of quality.
SAE 1OW-30 (3800 engine)
SAE 5W-30 (3100 engine)
Energy Conserving I1
Oils with these words on the
container will help you save fuel.
These three things are usually included
in a doughnut shaped logo (symbol) on
most containers.
If you cannot find oils
with the “starburst” symbol,
you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above. If
you use oils that do not have
either the “starburst” symbol or an
API SH or
SG designation, you can
cause engine damage not covered
by your warranty.
GM Goodwrench@ oil (in Canada, GM
Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your
Oldsmobile dealer is ready to advise if
you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 ltm).
It’s below freezing outside and most
trips are less than
10 miles (16 ltm).
The engine is at low speed most of the
time
(as in door-to-door delivery, or in
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your vehicle,
then you need to change your
oil and
filter every 3,000 miles (5 000 ltm) or 3
months - whichever comes first.
If none
of them is true, change the oil
every
7,500 miles (12 500 ltm) or 12
months -whichever comes first.
Change the filter at the first oil change
and at every other oil change after that.
Engine Coolant Heater (Engine
Block Heater)
An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If
your vehicle has this option, see
Engine
Coolant Heater in the Index. 193

Service &Appearance Cure
NOTICE:
198
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair
cost
wouldn’t be covered by your
warranty. Too much water in the
mix can freeze and crack the
engine, radiator, heater core and
other parts.
Adding Coolant
To Check Coolant
When your engine is cold, the coolant
level should be at
COLD, or a little
higher. When your engine is warm, the
level should be up to
FULL HOT, or a
little higher.
