236 Driving and Operating
At low temperatures, wax flakes are
more likely to form in Number 2-D
fuel than in Number 1-D (or
"winterized" Number 2-D) fuel. For
best operation at temperatures
below -7 °C (20 °F), use Number
1-D, or Number 2-D which has been
blended with Number 1-D for winter
use. When temperatures are
consistently below (or near) -18 °C
(0 °F), use Number 1-D if at all
possible. Bear in mind, however,
that even Number 1-D fuel will form
wax flakes when temperatures are
extremely low.
Do not use home heating oil or
gasoline in your diesel engine;
either may cause engine damage.
The addition of kerosene will not
unplug a filter plugged with wax.
Warming a "waxed" filter to a
temperature of 0 °C to 10 °C (32 °F
to 50 °F) will return the wax to
solution. Filter replacement is not
normally required.Water in Fuel (Diesel)
During refueling, it is possible for
water (and other contaminants) to
be pumped into your fuel tank along
with the diesel fuel. This can occur if
a service station does not regularly
inspect and clean its fuel tanks, or if
a service station receives
contaminated fuel from its
supplier(s).
To protect your engine from
contaminated fuel, there is a water
separator system on the engine
which allows you to drain excess
water from the fuel.
{Warning
The drained water/diesel fuel
mixture is flammable, and could
be hot. To help avoid personal
injury or death and/or property
damage, do not touch the fuel
coming from the water separator
drain valve, and do not expose
the fuel to open flames or sparks.(Continued)
Warning (Continued)
Be sure you do not overfill the
drain pan. Heat (such as from the
engine) can cause the fuel to
expand. If the container is too full,
fuel could be forced out of the
pan. This could lead to a fire and
the risk of personal injury and/or
vehicle damage.
Biocides
In warm or humid weather, fungus,
and/or bacteria may form in diesel
fuel if there is water in the fuel.
Fungus or bacteria can cause fuel
system damage by plugging the fuel
lines, fuel filters or injector. They
can also cause fuel system
corrosion.
If fungus or bacteria has caused fuel
system problems, you should have
your authorized dealer correct these
problems. Then, use a diesel fuel
biocide to sterilize the fuel system
(follow the biocide manufacturer's
instructions). Biocides are available
from your dealer, service stations,

2. Select the correct fuel (See"Diesel Fuel Requirement and
Fuel System"). Follow any
posted safety rules. Stand to
the side, never above or
opposite the filler opening.
3. Check that the fuel cap is tight, and see to it that engine oil,
engine coolant in the reservoir,
and washer fluid, etc. are at
proper levels. Then do the
Driver Daily Checklist.
See Owner Checks and Services
0 367.
Driving your vehicle until the fuel
tank is empty may activate the
check engine malfunction indicator
light. You do not need to have your
vehicle checked. After refueling,
perform the following:
. Bleed the fuel system.
. Start, turn off and restart the
engine three or four times.
. The check engine malfunction
indicator light will be cancelled. Before Starting the Engine
1. The priming pump (1) is
located on the outboard side of
the left frame rail, in front of the
batteries. Place a container
beneath the air bleed plug (2)
to receive fuel, and then fully
loosen the plug.
2. Attach a clear hose onto the air bleed plug, direct the clear
hose into a catch pan.
3. Pump the priming pump (1) up/ down for 65 times to get most
of the air bubbles out. Note fuel
was drawn into the filter bowl at
around 40 - 50 times. 4. Fully retighten the air bleed
plug (2) and wipe off any fuel
that may have adhered to the
plug or surrounding area.
5. Continue to operate the pump for 50 times.
6. Start the engine.
7. If the engine does not start, repeat steps 5 and 6 as
necessary until it does start.
After Starting the Engine 1. Without pressing the accelerator pedal, start the
engine.
2. After the engine has started, allow it to idle for about
5 seconds.
3. Fully press the accelerator pedal and increase the engine
speed to the maximum speed
for 10 seconds. (Repeat this
operation several times.)
Insufficient air bleeding can result in
faulty engine operation. Be sure,
therefore, to always carry out the
previous steps under "After starting
the engine".

Vehicle Care 247
For diesel vehicles, when working
on the fuel line or fuel filter, remove
the fuel tank filler cap. The fuel
system is under pressure and the
fuel will overspill unless the
pressure is relieved, possibly
leading to combustion or a fire.
Do not make engine adjustments
yourself. Be sure to consult your
dealer.
Use only appropriate tools.
Oils, brake fluid and engine coolant
have lubrication, cooling and rust
prevention functions. If these liquids
deteriorate through loss or
contamination, it will cause a
decline in the performance of the
parts and such problems as seizure
or malfunctioning. Replenish or
change these liquids when
performing the checks (daily and
periodic checks) as required by the
relevant regulations or in
accordance with the Maintenance
Schedule (when either the specified
driving distance or period of time,
whichever comes first, has expired).Confirm that all systems and
components are normal after
performing the work.
Do not leave the removed parts or
tools in the engine compartment.
They could damage the equipment if
caught in the belts or other moving
components.
Dirty water, dirt and other impurities
seriously impair the effectiveness of
the oil, grease and fluids, and
damage the parts. Exercise all due
caution to prevent waste or other
refuse from coming in contact with
parts or materials that have been
removed when changing or
replenishing them.
Do not step on the engine or climb
onto it. You could cause an engine
failure by, for example, damaging
the cylinder head cover or various
connectors.
Electric Welding
Careless electric welding of vehicle
parts can cause welding current to
flow back through the vehicle’s
ground circuit and damage electrical
and electronic parts so that they donot function normally. Whenever
electric welding is necessary,
consult your dealer.
Cab Tilting
Before Tilting the Cab (Single Cab
Model)
{Warning
To help avoid personal injury and
property damage:
. Park the vehicle on level
ground and check that there
is enough space in front of
and above the cab.
. Set the parking brake firmly
and block the front wheels.
. Move the selector lever in
the "P" position.
. Secure loose articles in
the cab.
. Stop the engine.
. Close the cab door.

Engine Coolant Reserve Tank
Inspection Cover (Crew Cab
Model) 5.2L Diesel
To gain access to the engine
coolant reserve tank, remove the
inspection cover located under the
rear left seat.
Engine Oil (Diesel)
Engine oil is an important factor
determining engine performance
and longevity. Be sure to use only
the specified oil and oil filters. The
engine oil level must be checked
and the oil should be changed
regularly according to the
Maintenance Schedule.The engine oil performs the
following important functions:
.
It prevents engine parts from
becoming worn.
. It cools engine parts.
. It cleans engine parts.
. It seals the combustion
chambers and prevents rust.
Replace the engine oil at regular
intervals.
When particulate matter (PM) has
accumulated to a preset level in the
diesel particulate filter (DPF), the
filter is automatically regenerated
through combustion. To make this
regeneration (combustion) possible,
a small amount of fuel is injected
into the engine combustion chamber
after firing. This causes fuel to
gradually become mixed with the
engine oil, and the engine oil level
may rise beyond the original level.
This does not indicate a malfunction
of the engine.
Access to the Engine
Single Cab Model
Access to the engine oil dipstick is
located on the engine left side after
tilting the cab. See Cab Tilting
0 247.
Crew Cab Model
The engine oil dipstick is under the
engine inspection sub cover located
beneath the driver's seat.

10716700) - 2017 - crc - 12/6/16
254 Vehicle Care
Adding oil above the "Position A"
mark on the oil dipstick could result
in faulty engine operation. Be sure
to check the oil level by using the oil
dipstick.
Failure to use the recommended
engine oil could result in engine or
DPF breakdown, or in poor fuel
efficiency. Be sure to use the
recommended engine oil.
Choosing the Right Quality Oil
If you do not use the oil intended for
a vehicle equipped with a Diesel
Particulate Filter (DPF), both the
engine and the DPF may break
down and fuel economy may
decrease. Be sure, therefore, to use
the oil intended for vehicles
equipped with DPF.
GM recommends engine oil that
supports DPF (Low ash oil). Use of
engine oil that does not support low
ash will increase the PM produced
by engine combustion.
Consequently, the maintenance
interval of the DPF filter will be
reduced.Oil Identification Logo
A logo (symbol) is used on most oil
containers to help you select the oil
you should use. The top portion of
the logo shows the oil quality by API
designations such as CK4 or others.
The center portion of the logo
shows the SAE viscosity grade,
such as SAE *W-40 (* indicates
viscosity on the low temperature
side). You should look for this logo
on the oil container, and use ONLY
oil containing the logo.
Change Intervals
The oil and oil filter change intervals
for your engine are based on the
use of recommended oil quality and
viscosity, as well as high-quality
filters such as genuine GM oil filters.
Using oil other than recommended,
or oil and filter change intervals
longer than recommended, could
reduce engine life. Damage to
engines due to improper
maintenance or use of incorrect oil
quality and/or viscosity is not
covered by the new vehicle
warranty.
Your engine was filled with a
high-quality engine oil when it was
built. You do not have to change this
oil before the first recommended
change interval. Oil and filter
change intervals depend on how
you use your vehicle. For
information on the proper oil and
filter change intervals. See
Maintenance Schedule
0345.

256 Vehicle Care
This Engine Oil Viscosity Grade
Chart shows general information.
For this vehicle, oil with *W-40
viscosity is recommended.
Changing the Engine Oil and
Oil Filter
Engine oil and the oil filter are
important factors in engine
performance and lifespan. Be sure
to use only the specified oil and oilfilters. The engine oil level must be
checked and the oil should be
changed regularly according to the
Maintenance Schedule.
Use the indicated oil quantities only
as guidelines when changing the
engine oil. After changing the oil,
make sure the oil is at the required
level. See
Capacities and
Specifications 0389. Failure to use the recommended
engine oil could result in engine or
DPF breakdown, or in poor fuel
efficiency. Be sure to use the
recommended engine oil.
Engine oil change precaution:
.
When adding oil, remove the
dipstick.
. After adding oil, wait for at least
5 minutes before starting the
engine. Be sure to reinstall the
dipstick.
Discarded Parts, Oils and
Other Liquids
When changing oils, filters, engine
coolant or other liquids, be sure to
have a container ready in advance
for their disposal.
Use methods conforming to legal
requirements for discarding or
disposing of parts, oils, filters or
engine coolant after change or
replacement.
Do not dispose of used engine oil,
fuel or any other oil in a careless
manner such as pouring it on the
ground, into sewers, or into streams

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-
10716700) - 2017 - crc - 12/6/16
260 Vehicle Care
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Automatic Transmission
Fluid
{Warning
Overfilling of the automatic
transmission can cause the fluid
to be "PURGED" out of the
breather hose onto the hot engine
parts and can cause a fire.
You and others could be seriously
injured.
Both quality and quantity of fluid are
important factors that have a
significant influence on the
performance and durability of the
automatic transmission. Be sure to use only the dealer recommended
fluid for replenishment, and observe
the specified fluid level.
Too much or too little transmission
oil could damage your transmission.
Too much could cause your
transmission to overheat and fluid to
spill out from the breather hose. Be
sure to get an accurate reading if
you check your transmission fluid.
When cleaning around the dipstick
and guide tube, make sure that you
thoroughly wipe away all of the dirt
and dust etc. Failure to do so may
cause a fault in the transmission.
Do not let coolants (ethylene glycol
type), water based substances,
or other fluids etc., mix with the
fluid. Otherwise, degraded
performance and faulty operation of
the system will result.
Checking the Automatic
Transmission Oil level
This operation could be difficult and
you may choose to have this done
at your dealer.
If you choose to do it yourself, then
be sure to follow all the instructions
below or you could get a false
reading on the dipstick.
Position of the Dipstick
For the single cab diesel vehicle,
the dipstick is located to the left side
of the automatic transmission at the
rear of the engine. Tilt the cab up to
inspect it.
