2007 CHEVROLET EXPRESS PASSANGER open hood

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord for the engine coolant heater is
located on the driver’s side of the engine
compartment and is attached to the hose for
the power steering reservoir.
3. Plug it into a normal, grounded 110-volt
AC outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer/retailer in the area where you will be parking
your vehicle. The dealer/retailer can give you
the best advice for that particular area.

Gasoline Octane
Use regular unleaded gasoline with a posted
octane rating of 87 or higher. If the octane rating
is less than 87, you might notice an audible
knocking noise when you drive, commonly referred
to as spark knock. If this occurs, use a gasoline
rated at 87 octane or higher as soon as possible.
If you are using gasoline rated at 87 octane or
higher and you hear heavy knocking, the engine
needs service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specification D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). General Motors recommends against the
use of gasolines containing MMT. SeeAdditives
on page 294for additional information.
California Fuel
If your vehicle is certified to meet California
Emissions Standards, it is designed to operate
on fuels that meet California specifications.
See the underhood emission control label.
If this fuel is not available in states adopting
California emissions standards, your vehicle will
operate satisfactorily on fuels meeting federal
specifications, but emission control system
performance may be affected. The malfunction
indicator lamp may turn on and your vehicle may
fail a smog-check test. SeeMalfunction Indicator
Lamp on page 178. If this occurs, return to
your authorized GM dealer for diagnosis. If it is
determined that the condition is caused by the
type of fuel used, repairs may not be covered
by your warranty.

Checking Things
Under the Hood
{CAUTION:
Things that burn can get on hot engine or
fuel operated heater (FOH) 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 or fuel operated heater (FOH).
Hood Release
To open the hood, do the following:
1. Pull the handle with
this symbol on it.
It is located in front
of the driver’s
side door frame
near the floor.

If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Just
turn it off and get everyone away from
the vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned.
Stop your engine if it overheats, and get
out of the vehicle until the engine is cool.
Notice:If your engine catches re because
you keep driving with no coolant, your vehicle
can be badly damaged. The costly repairs
would not be covered by your warranty.
If No Steam Is Coming From
Your Engine
If you get an engine overheat warning but see
or hear no steam, the problem may not be
too serious. Sometimes the engine can get a
little too hot when you:
•Climb a long hill on a hot day.
•Stop after high-speed driving.
•Idle for long periods in traffic.
•Tow a trailer. See “Driving on Grades”
underTowing a Trailer on page 269.
If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is safe to
do so, pull off the road, shift to PARK (P)
or NEUTRAL (N) and let the engine idle.
2. Turn on your heater to full hot at the highest
fan speed and open the windows as
necessary.

4. Open the hoods and locate the positive (+)
and negative (−) terminal locations of the
other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−)
jump starting terminal. You should always
use these remote terminals instead of
the terminals on the battery.
The remote positive (+) terminal is located
behind a red plastic cover near the engine
accessory drive bracket on the driver’s side of
the engine compartment, below the alternator.
To uncover the remote positive (+) terminal,
open the red plastic cover.
The remote negative (−) terminal is located on
the engine drive bracket on all V8 engines
and is marked GND (Ground).
On V6 engines the remote negative (−)
terminal is located on a tab attached to
the engine accessory drive bracket and is
marked GND (Ground).
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the battery
installed in your new vehicle. But if a
battery has ller caps, be sure the right
amount of uid is there. If it is low, add
water to take care of that rst. If you do
not, explosive gas could be present.
Battery uid contains acid that can
burn you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.

(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine parts as needed. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap and cleaning the outside of the
radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield Wiper
Blade Replacement on page 344 and Windshield
and Wiper Blades on page 387 for more
information.
(e)Make sure the safety belt reminder light and
all belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.(f)Lubricate all key lock cylinders, hood hinges,
hood prop rod pivot, hood latch assembly,
secondary latch, pivots, spring anchor, release
pawl, rear compartment hinges, latches, locks, fuel
door hinge, and any moving seat hardware. More
frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease
on weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Vehicles with Gross Vehicle Weight Rating
(GVWR) above 10,000 lbs (4 536 kg) only: Inspect
shields for damage or looseness. Adjust or
replace as required. This is a Noise Emission
Control Service. Applicable to vehicles sold in the
United States and recommended for vehicles
sold in Canada.
(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
-In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
-In hilly or mountainous terrain.
-When doing frequent trailer towing.
-Uses such as found in taxi, police,
or delivery service.
