Running Out of Fuel
If the diesel engine stalls and you think that you
have run out of fuel, do this to restart your engine:
{CAUTION:
Diesel fuel is ammable. It could start a
re if it gets on hot engine parts. You
could be burned. Do not let too much fuel
ow from the air bleed valve, and wipe up
any spilled fuel with a cloth.
1. If you are parked on a level surface, add at
least 2 gallons (7.6 liters) of fuel. However, if
you are parked on a slope, you may need
to add up to 5 gallons (18.9 liters) of fuel.
2. Follow the fuel priming procedure earlier in
this section to prime the fuel filter.3. Close the air bleed valve.
4. Turn the ignition key to START for 10 to
15 seconds at a time until your engine
starts. If the engine tries to run, but does not
run smoothly, increase the rpm a little
using the accelerator pedal. This will help
force air through the system.
Your check engine light may come on if the
vehicle has run out of fuel. This light may stay on
for a few drive cycles after the condition is
corrected, but will eventually clear itself.

Fuel Filter Replacement
If you want to change the diesel engine fuel filter
yourself, here is how to do it:
{CAUTION:
Diesel fuel is ammable. It could start a
re if something ignites it, and you could
be burned. Do not let it get on hot engine
parts, and keep matches or other ignition
sources away.
First, drain any water from the filter by following
the water draining procedure earlier in this section.
Your vehicle’s engine should be off until the end
of this procedure.
If your vehicle has the 6.6L engine, the fuel filter is
located in the engine compartment on the
driver’s side of the vehicle. If your vehicle has
either the 7.2L or 7.8L engine, the fuel filters are
located in the engine compartment on the
driver’s side of the vehicle, and on the driver’s
side frame rail in front of the fuel tank.
1. Apply the parking brake.2. Unplug the water
sensor wire
connected to the fuel
filter and unscrew
the filter element.
3. Remove the filter element. If there is any dirt
on the filter sealing surface, clean it off.
Remove and reuse the water sensor float
switch located on the bottom of the fuel filter.
4. Install the new filter element.
5. Reinstall and tighten the filter container and
reconnect the water sensor wire to the filter.
6. Use the fuel filter priming procedure earlier in
this section to prime the fuel filter.
7. Tighten the air bleed valve by turning it
clockwise until hand-tight.
8. Start your engine and let it idle for
five minutes. Check your fuel filter and air
bleed valve for leaks.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it
is in your vehicle. Static electricity
discharge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup
bed, or on any surface other than the
ground.
Bring the ll nozzle in contact with the
inside of the ll opening before
operating the nozzle. Contact should
be maintained until the lling is
complete.
Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.
266

When you tilt the hood far enough, the cables will
support it. When you close the hood, make
sure both latches are secured.
Engine Oil (Caterpillar®Diesel
Engine)
See your Caterpillar®Operation & Maintenance
Manual for information on oil quality and viscosities
as well as the temperature range chart.
Engine Oil (Gasoline Engine)
If the low oil light
appears on the
instrument cluster, it
means you need
to check the engine oil
level right away.
For more information, seeLow Oil Level Light on
page 176.
You should check the engine oil level regularly;
this is an added reminder.
268

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil
dipstick is located in the
engine compartment
on the driver’s side
of the vehicle.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a 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
If the oil is below the cross-hatched area at the tip
of the dipstick, you will need to add at least one
quart/liter of oil. But you must use the right
kind. This section explains what kind of oil to use.
For engine oil crankcase capacity, seeCapacities
and Specications on page 347.
Notice:Do not add too much oil. If 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.
269

Engine Oil (DURAMAX®/Isuzu Diesel
Engine)
Checking Engine Oil
It is a good idea to check the engine oil level
every time you get fuel.
The engine oil dipstick
is located in the engine
compartment on the
driver’s side of the
vehicle.In order to get an accurate reading, the engine
should be at normal operating temperature, so
that the oil is warm, and the vehicle must be
on level ground.
1. If the engine is at normal operating
temperature and the oil is warm, turn off the
engine and allow at least five minutes for
the oil to drain back into the oil pan. If you do
not do this, the oil dipstick might not show
the actual level.
If the engine has not been run long enough to
bring it up to normal operating temperature
and the oil is cool, turn off the engine and allow
30 minutes for the oil to drain back into the
oil pan. If you do not do this, the oil dipstick
might not show the actual level.
2. Pull out the dipstick and clean it with a
paper towel or a cloth, then push it back
in all the way.

3. Remove the dipstick again, keeping the tip
down, and check the oil level.When to Add Engine Oil
If the oil is below the cross-hatched area at
the tip of the dipstick for the 6.6L V8 DURAMAX®
engine, you will need to add at least
two quarts/liters of oil. If the oil is below the
lower hole at the tip of the dipstick for the Isuzu
6H engine, you will need to add at least one
quart/liter of oil. But you must use the right kind.
This section explains what kind of oil to use.
For engine oil crankcase capacity, seeCapacities
and Specications on page 347.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above the
cross-hatched area for the 6.6L V8 (LLY) engine
or above the upper hole that shows the proper
operating range for the 7.8L L6 (LG4) engine,
the engine could be damaged.

GM Goodwrench®oil of the recommended
viscosity grades meets all the requirements for
your vehicle.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the API service symbol are all you will
need for good performance and engine protection.
When to Change Engine Oil (Vehicles
Without the Engine Oil Life System)
If you have the 6.6L V8 DURAMAX®Engine:
Change engine oil and filter every 15,000 miles
(24 000 km), or every 12 months, or every
750 hours of engine operation, whichever occurs
first. If you have the Isuzu 6H Engine: Change
engine oil and filter every 12,000 miles
(20 000 km), or every 12 months, or every
600 hours of engine operation, whichever occurs
first. SeeScheduled Maintenance on page 363.
Engine Oil Life System
(Gasoline Engine)
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and filter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change
will be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change is
necessary. A change engine oil light will come on.
SeeChange Engine Oil Light on page 176. Change
your oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for
over a year. However, your engine oil and filter
must be changed at least once a year and at this
time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system.
It is also important to check your oil regularly and
keep it at the proper level.

Engine Oil Life System
(DURAMAX
®Diesel)
When to Change Engine Oil
If your vehicle has the Engine Oil Life System, it
has a computer system that lets you know when to
change the engine oil and filter. This is based
on injection timing, engine load and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change
will be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A change engine oil light will
come on. SeeChange Engine Oil Light on
page 176. Change your oil as soon as possible
within the next 600 miles (1 000 km) or 30 hours of
engine operation, whichever occurs first. It is
possible that, if you are driving under the best
conditions, the oil life system may not indicate that
an oil change is necessary for over a year.However, your engine oil and filter must be
changed at least once a year and at this time the
system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the
system. It is also important to check your oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 15,000 miles (24 000 km),
or 150 hours of engine operation, whichever
occurs first, since your last oil change. Remember
to reset the oil life system whenever the oil is
changed.
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and filter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change your oil prior to a change engine oil light
being turned on, reset the system.

3. Store the seal in the inlet, located on the
underside of the hood
4. Store the clamp on the coolant surge tank.
Pull the overflow tube out of the white
plastic retainer, slip the clamp over and
reinstall the hose.
The seal will need to be replaced on to the air
cleaner for normal driving, especially in the
warmer months.
Automatic Transmission Fluid
When to Check
A good time to check your automatic transmission
fluid level is when the engine oil is checked.
