the dipstick, wipe it with a clean
paper towel or cloth, then push it
back in all the way. Remove it
again, keeping the tip down, and
check the level.
When to Add Engine Oil
Gasoline
Diesel
If the oil is below the cross-hatched
area at the tip of the dipstick and
the engine has been off for at least
15 minutes, add 1 L (1 qt) of the
recommended oil and then recheck the level. See
“Selecting the Right
Engine Oil” later in this section for
an explanation of what kind of oil to
use. For engine oil crankcase
capacity, see Capacities and
Specifications 0364.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
0 262 for the location of the engine
oil fill cap. Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
(Gasoline Engines)
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See
Recommended Fluids and
Lubricants 0359.
Specification
Ask for and use full synthetic engine
oils that meet the dexos1
specification.
Engine oils that have been
approved by GM as meeting the
dexos1 specification are marked
with the dexos1 approved logo. See
www.gmdexos.com.

Vehicle Care 267
Caution
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty.
Viscosity Grade
Use one of the following engine oils:
. Dexos1 approved ACDelco Full
Synthetic 0W20 engine oil.
. Dexos1 approved Mobil 1 Full
Synthetic 0W20 engine oil.
. Or any other 0W20 engine oil
meeting dexos1 second
generation requirements.
When selecting an oil of the
appropriate viscosity grade, it is
recommended to select an oil of the
correct specification. See
“Specification” earlier in this section.
Selecting the Right Engine Oil
(Diesel Engines)
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade:
Specification
Ask for and use engine oils that
meet the dexos2 specification.
Engine oils that have been
approved by GM as meeting the
dexos2 specification are marked
with the dexos2 approved logo. See
www.gmdexos.com.
Caution
Use only engine oil that is
approved to the dexos2
specification or equivalent engine
oil as defined in the preceding
(Continued)
Caution (Continued)
paragraph. Failure to use the
recommended engine oil can
result in engine damage not
covered by the vehicle warranty.
Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29 °C
(−20 °F), an SAE 0W-40 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade, it
is recommended to select an oil of
the correct specification. See
“Specification” earlier in this section.

When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing and
inspecting the engine air cleaner/
filter, seeMaintenance Schedule
0 350.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
cleaner/filter housing open. Before
removing the engine air cleaner/
filter, make sure that the engine air
cleaner/filter housing and nearby
components are free of dirt and
debris. Remove the engine air
cleaner/filter. Lightly tap and shake
the engine air cleaner/filter (away
from the vehicle), to release loose
dust and dirt. Inspect the engine air
cleaner/filter for damage, and
replace if damaged. Do not clean
the engine air cleaner/filter or
components with water or
compressed air. To inspect or replace the engine air
cleaner/filter:

2. Air Inlet Duct
3. Air Duct Clamp
4. Electrical Connector
1. Disconnect the harness connector from the air cleaner/
filter cover electrical
connector (4).
2. Remove the air inlet duct (2). 3. Loosen the screw on the air
duct clamp (3) holding the air
outlet duct in place. Do not
remove the clamp. Move the
air duct aside.
4. Remove the four air cleaner/ filter housing cover screws (1).
5. Raise the air cleaner/filter housing cover and remove the
air cleaner/filter from the air
cleaner/filter housing.
6. Clean the air cleaner/filter sealing surface and the air
cleaner/filter housing.
7. Install the new engine air cleaner/filter.
8. Lower the air cleaner housing cover and secure with the four
screws (1).
9. Install the air inlet duct (2).
10. Install the air duct and tighten the screw on the air duct
clamp (3) to secure it to the air
cleaner/filter housing.

{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.

1. Engine Cooling Fan (Outof View) 2. Engine Coolant Surge Tank
and Pressure Cap
{Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.

3. Fill the coolant surge tank with the proper mixture to the
indicated level mark.
4. With the coolant surge tank pressure cap off, start the
engine, switch off the A/C and
let the engine run until the
upper radiator hose can be felt
getting hot. Watch out for the
engine cooling fan. By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level reaches the
indicated level mark.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight.
6. Verify coolant level after the engine is shut off and the
coolant is cold. If necessary,
repeat coolant fill procedure
Steps 1–6.
If the coolant still is not at the
proper level when the system
cools down again, see your
dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.
Engine Overheating
The vehicle has an engine coolant
temperature gauge on the
instrument cluster to warn of engine
overheating. See Engine Coolant
Temperature Gauge 0127.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. Contact
your dealer for additional
information.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine, and have the
vehicle serviced.
Caution
Do not run the engine if there is a
leak in the engine cooling system.
This can cause a loss of all (Continued)

recommended draining and
replacement intervals.
Starter Switch Check
{Warning
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle.
2. Apply both the parking brake and the regular brake.
Do not use the accelerator
pedal, and be ready to turn off
