2007 CHEVROLET OPTRA 5 oil

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.
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 provide
easier cold starting and better protection for
the engine at extremely low temperatures.
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 need for
good performance and engine protection.
When to Change Engine Oil
If any one of these is true for you, use the
short trip/city maintenance schedule:
•Most trips are less than 5 miles (8 km).
This is particularly important when outside
temperatures are below freezing.
•Most trips include extensive idling, such as
frequent driving in stop-and-go traffic.
•You frequently tow a trailer or use a carrier
on top of your vehicle.
•The vehicle is used for delivery service,
police, taxi, or other commercial application.
Driving under these conditions causes engine oil
to break down sooner. If any one of these is
true for your vehicle, change the oil and filter every
3,000 miles (5 000 km) or 3 months, whichever
occurs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and
filter every 7,500 miles (12 500 km) or 12 months,
whichever occurs first. Driving a vehicle with a
fully warmed engine under highway conditions will
cause engine oil to break down slower.

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 filter 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
used oil, ask your dealer, a service station, or a
local recycling center for help.
Engine Air Cleaner/Filter
The engine air cleaner/filter is located in the
engine compartment on the passenger’s side of
the vehicle. SeeEngine Compartment Overview
on page 258for more information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the engine air cleaner/filter every
15,000 miles (25 000 km) and replace it every
30,000 miles (50 000 km). If you are driving
in dusty/dirty conditions, inspect the filter at each
engine oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect the engine air cleaner/filter remove the
filter from the vehicle and lightly shake the filter
to release loose dust and dirt. If the filter remains
caked with dirt, a new filter is required.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid
level. If a leak occurs, take the vehicle to
the dealership service department and have it
repaired as soon as possible. You may also have
your fluid level checked by your dealer or
service center when you have your oil changed.
Notice:Use of automatic transaxle uid
labeled other than ESSO LT71141 or
TOTAL ATF H50235 may damage your vehicle,
and the damages may not be covered by
your warranty. Always use ESSO LT71141
or TOTAL ATF H50235 labeled automatic
transaxle uid.
Manual Transaxle Fluid
It is not necessary to check the transaxle fluid
level. A transaxle fluid leak is the only reason for
fluid loss. If a leak occurs, take the vehicle to
the dealership service department and have
it repaired as soon as possible. SeePart D:
Recommended Fluids and Lubricants on page 382
for the proper fluid to use.
Hydraulic Clutch
There is one reservoir for both the brake and the
hydraulic clutch fluid. SeeBrakes on page 281
for more information.
The hydraulic clutch linkage in your vehicle is
self-adjusting. The master cylinder reservoir
is filled with hydraulic fluid.
266

Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for five years
or 150,000 miles (240 000 km), whichever
occurs first, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 271.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
•Give freezing protection down to
−34°F (−37°C).
•Give boiling protection up to 265°F (129°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as
they should.Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant which will
not damage aluminum parts. If you use this coolant
mixture, you do not need to add anything else.
268

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and other parts.
If you have to add coolant more than four times a
year, have your dealer check your cooling system.
Notice:If you use extra inhibitors and/or
additives in your vehicle’s cooling system,
you could damage your vehicle. Use only the
proper mixture of the engine coolant listed
in this manual for the cooling system.
SeePart D: Recommended Fluids and
Lubricants on page 382for more information.
269

{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
Make sure that the air conditioning is turned off.
The coolant level should be between the Minimum
and Maximum marks on the coolant surge tank
when the engine is cool. If it is not, you may have
a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak.
If you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.
274

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and a proper coolant.Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant
and the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
276

What to Add
When you do need brake fluid, use only DOT-3
brake fluid. Use new brake fluid from a sealed
container only. SeePart D: Recommended Fluids
and Lubricants on page 382.
Always clean the brake fluid reservoir cap and
the area around the cap before removing it.
This helps keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake uid.Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 339.
