engine CHEVROLET EQUINOX 2007 1.G Manual PDF

Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected. The
malfunction indicator lamp may turn on. If this
occurs, return to your dealer for service.
Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel may
be hard to nd. Never use leaded gasoline or
any other fuel not recommended in the previous
text on fuel. Costly repairs caused by use of
improper fuel would not be covered by your
warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business
in the country where you will be driving.
Filling the Tank
{CAUTION:
Fuel vapor burns violently and a fuel re
can cause bad injuries. To help avoid
injuries to you and others, read and follow
all the instructions on the pump island.
Turn off your engine when you are
refueling. Do not smoke if you are near
fuel or refueling your vehicle. Keep
sparks, ames, and smoking materials
away from fuel. Do not leave the fuel
pump unattended when refueling your
vehicle. This is against the law in some
places. Keep children away from the fuel
pump; never let children pump fuel.

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{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.

Engine Oil
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 handle is a yellow loop.
SeeEngine Compartment Overview on page 342
for the location of the engine oil dipstick.
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 434.
344

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.
SeeEngine
Compartment Overview
on page 342for the
location of the engine oil
ll cap.Be sure to add enough oil to put the level
somewhere in the proper operating range in the
cross-hatched area. Push the dipstick all the
way back in when you are through.
SAE 5W-30 may not
appear on all caps.
345

What Kind of Engine Oil to Use
Look for two things:
GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. You should look for
and use only an oil that meets GM Standard
GM6094M.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle. If you are in an area
of extreme cold, where the temperature falls
below−20°F (−29°C), it is recommended
that you use either an SAE 5W-30 synthetic oil
or an SAE 0W-30 oil. Both will provide
easier cold starting and better protection for
the engine at extremely low temperatures.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
also have the starburst
symbol on the
container. This symbol
indicates that the oil
has been certied by the
American Petroleum
Institute (API).
You should look for this information on the oil
container, and use only those oils that are identied
as meeting GM Standard GM6094M and have the
starburst symbol on the front of the oil container.
346

Notice:Use only engine oil identied as
meeting GM Standard GM6094M and showing
the American Petroleum Institute Certied For
Gasoline Engines starburst symbol. Failure to
use the recommended oil can result in engine
damage not covered by your warranty.
GM Goodwrench
®oil meets all the requirements
for your vehicle.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for good
performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter. 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 and a
CHANGE ENGINE OIL SOON message will come
on. 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 lter 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 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed.
347

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter 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
or CHANGE ENGINE OIL SOON message
being turned on, reset the system.
1. Turn the ignition key to RUN with the
engine off.
2. Fully press and release the accelerator pedal
three times within ve seconds.
The change engine oil light will ash while the
system is resetting.
3. When the light stops ashing, turn the key
to LOCK.
If the light or message comes back on and stays
on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may
be unhealthy for your skin and could even cause
cancer. Do not let used oil stay on your skin for very
long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine
oil. See the manufacturer’s warnings about the use
and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of your
used oil, ask your dealer, a service station, or a
local recycling center for help.

Engine Air Cleaner/Filter
The engine air cleaner/lter is located in the
engine compartment on the passenger’s side of
the vehicle. SeeEngine Compartment Overview on
page 342for more information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval. See
Scheduled Maintenance on page 439for more
information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine oil
change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect the air cleaner/lter remove the lter
from the vehicle and lightly shake the lter to
release loose dust and dirt. If the lter remains
caked with dirt, a new lter is required.To inspect or replace the engine air cleaner/lter,
do the following:
1. Turn off the engine.
2. Disconnect the air ow sensor electrical
connector.
