engine CHEVROLET VENTURE 1998 Repair Manual

NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t
use your compact spare on other vehicles.
And don’t
mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
If You’re Stuck: In Sand, Mud,
Ice
or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels
too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
I
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire
or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.

L
You can be injured and your ve :le could be
damaged if you try to do service work on a
vehicle without knowing enough about
it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners, “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall
off. You could be hurt.
Adding Equipment to the - hide of
Your Vehicle
Things you might add to the outside of your vehicIe can
affect the airflow around
it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside
of
your vehicle. Use regular unleaded gasoline rated at
87 octane
or
higher. At
a minimum, it should meet specifications
ASTM
D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the
AAMA
specification could provide improved driveability
and emission control system protection compared to
other gasolines.
Be sure the posted octane is at least 87. If the octane is
less than 87,
you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at
87 octane or higher and you
hear heavy knocking, your engine needs service. But
don’t worry if you hear a little pinging noise when
you’re accelerating or driving up
a hill. That’s normal,
and you don’t have
to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have
a problem.
ProCarManuals.com

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label),
it is designed to operate on fuels that meet
California specifications. If such fuels are 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 on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If
this occurs, return
to your authorized Chevrolet dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type
of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines. If fuels containing
MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Chevrolet dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Checking Things Under the Hood
I A CAUTION: I
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.
A CAUTION:
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, 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.
Hood Release
To open the hood, first pull the hood release handle
inside
the vehicle.

: . ... , .., . ,
Then go to the front of the vehicle and push up on the
underhood release.
Lift the hood.
The hood prop may be hot due to increased engine
temperatures under the hood,
so be careful when
handling
it. Use your hood prop sleeve when handling
the hood prop.
Pull forward on the hood
prop to release it from its
storage clip. Then put the
end
of the hood prop into
the slot in the underside of
the hood.

Before closing the hood, be sure all the filler caps are
on properly. Then lift the hood to relieve pressure on
the hood prop. Remove the hood prop from the slot in
the hood and return the prop
to its retainer. Then just
let the hood down and close it firmly.
Underhood Lamp (If Equipped)
Your underhood lamp will go on when you open
the hood.
Engine Oil
If the LEVEL light on
the instrument panel comes on, it means you need
to
level right away.

check your engine oil
For more information, see “LOW Oil Level Light” in the
Index. You should check your engine oil level regularly:
this
is an added reminder. It’s a good idea to check your 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
is located at the front of the
engine compartment, near the center. The dipstick
handle has a bright, yellow loop design for easy
identification.
Turn off the engine and give the oil a few minutes
to
drain back into the oil pan. If you don’t, the oil dipstick
might not show
the actual level.

Checking Engine Oil
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 at or below the ADD mark, then you’ll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind
of oil to use. For
crankcase capacity, see “Capacities and Specifications” in the Index.
NOTICE: I
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper
operating
range, your engine could be damaged.
The engine oil fill cap is
located just behind the
engine oil dipstick.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.

What Kind of Engine Oil to Use RECOMMENDED SAE YlSCOSlTT GRADE ENGINE OILS
Oils recommended for your vehicle can be identified
by loolung for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
b _- If you change your own
oil, be sure you use oil
that has the Starburst
symbol on
the front of the
oil container.
If you have
your oil changed for you,
be sure the oil put into
your engine
is American
Petroleum Institute certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
