4. Open the hood and unwrap theelectrical cord.
For V6 engines, the cord for
the engine coolant heater is on
the driver side of the engine
compartment.
For V8 engines, the cord for
the engine coolant heater is
behind the engine air cleaner/
filter.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
5. Plug it into a normal, grounded 110-volt AC outlet.{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
function. An ungrounded
outlet could cause an
electric shock.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make

property damage, electric
shock, and injury.
. Do not operate the vehicle
with the heater cord
permanently attached to the
vehicle. Possible heater
cord and thermostat
damage could occur.
. While in use, do not let the
heater cord touch vehicle
parts or sharp edges. Never

Engine Oil
For diesel engine vehicles, see
“Engine Oil” in the Duramax diesel
supplement.
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
. Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section. .
Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0237.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0232 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.

Vehicle Care 239
suspected, use the following
procedures to check the fluid level.
However, if there is a large leak, it
may be necessary to have the
vehicle towed to a dealer and have
it repaired before driving the vehicle
further.
Change the fluid and filter at the
intervals listed inMaintenance
Schedule 0319, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants 0327.
How to Check Automatic
Transmission Fluid
Because this operation can be
difficult, it is recommended to have
this check done at your dealer,
which can monitor the transmission
temperature. The transmission fluid
level increases with temperature. To
obtain a highly accurate fluid level
check, the transmission temperature
must be measured.
If it is decided to check the fluid
level, be sure to follow all the
instructions here, or a false reading
on the dipstick may occur.
Caution
Too much or too little fluid can
damage the transmission. Too
much can mean that some of the
fluid could come out and fall on
hot engine parts or exhaust
system parts, starting a fire. Too
little fluid could cause the
transmission to overheat. Be sure
to get an accurate reading if
checking the transmission fluid.
Wait at least 30 minutes with the
engine off, before checking the
transmission fluid level if the vehicle
has been driven:
. In hot weather, when outside
temperatures are above 32 °C
(90 °F).
. The vehicle is heavily loaded.
. At high speed for quite a while in
hot weather.
. In heavy traffic and hot weather.
. While pulling a trailer. After driving under these conditions,
a hot check can be performed. The
fluid should be hot, which is 71 °C to
93 °C (160 °F to 200 °F).
A cold fluid level check can be
performed after the vehicle has
been sitting for eight hours or more
with the engine off, but this is used
only as a reference. Let the engine
run at idle for five minutes if the
outside temperature is between
15 °C to 32 °C (60 °F to 90 °F).
Should the fluid level be low during
this cold check, the fluid must be
checked warm or hot before adding
fluid. If the outside temperature is
colder than 15 °C (60 °F) or hotter
than 32 °C (90 °F), a cold check
cannot be performed.
A warm fluid level check can be
performed by driving the vehicle
under lightly loaded conditions and
outside temperatures between 10 °C
to 27 °C (50 °F to 80 °F). The
vehicle should be driven for at least
24 km (15 mi) before performing a
warm check. Checking the fluid

242 Vehicle Care
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the correct
automatic transmission fluid. See
Recommended Fluids and
Lubricants0327.
Change the fluid and filter at the
scheduled maintenance intervals
listed in Maintenance Schedule
0 319. Be sure to use the
transmission fluid listed in
Recommended Fluids and
Lubricants 0327.
Engine Air Cleaner/Filter
The air cleaner/filter assembly is on
the front of the engine compartment
on the driver side of the vehicle.
See Engine Compartment Overview
0 232. When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing and
inspecting the engine air filter, see
Maintenance Schedule
0319.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
filter housing open. Before removing
the engine air filter, make sure that
the engine air filter housing and
nearby components are free of dirt
and debris. Remove the engine air
filter. Lightly tap and shake the
engine air filter (away from the
vehicle) to release dust and dirt.
Inspect the engine air filter for
damage, and replace if damaged.
Do not clean the engine air filter or
components with water or
compressed air.
4.3L V6 Engine
To inspect and replace the filter: 1. Remove the eight screws, slide the top cover forward and lift,
to gain access to the air
cleaner/filter.
2. Remove the air cleaner/filter from the housing base. Take
care to dislodge as little dirt as
possible.
3. Clean the air cleaner/filter sealing surface and
housing base.
4. Install the engine air cleaner/ filter in the housing base.

2. Housing Base
3. Housing Cover
To inspect and replace the filter:
1. Unlock the two retaining clips (1) on the sides of the
housing cover (3) and on the
housing base (2) and pull the
cover off. 2. Remove the air cleaner/filter
from the housing base. Take
care to dislodge as little dirt as
possible.
3. Clean the air cleaner/filter sealing surface and
housing base.
4. Install the engine air cleaner/ filter by aligning the arrow on
one side of the air cleaner/filter
end cap with the arrow on top
of the housing base.
5. Install the housing cover by aligning the arrow on top of the
cover to the arrow on top of the
housing base, and fasten the
two retaining clips.
See Maintenance Schedule 0319 to
determine when to replace the
engine air cleaner/filter.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. Use caution
when working on the engine. Do
not start the engine or drive the
vehicle with the air cleaner/filter
off, as flames may be present if
the engine backfires.
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.
