1997 CHEVROLET ASTRO engine oil

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
-----
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is
a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, start the engine again. See
if the fan speed increases when idle speed is doubled by
pushing the accelerator pedal down.
If it doesn’t, your
vehicle needs service. Turn off the engine.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
ADD mark, add a 50/50 mixture of clean water
(prefembly distilled) and DEX-COOL@ (silicate-free)
antifreeze at the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information.)
,/!
CAU [ON:
---
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and DEX-COOL@ coolant.

9. Remove any rust or dirt
from the wheel bolts, mounting surfaces and
spare wheel.
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use
a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
A CAI'TION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.
10. Put on the spare tire. Put the nuts on by hand. Make
sure the cone-shaped end
is toward the wheel.
Tighten each
nut by hand until the wheel is held
against the hub.
If a nut can't be turned by hand,
use
the extension and see your dealer as soon
as possible.

Downloaded from www.Manualslib.com manuals search engine 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.
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
find. Never use leaded gasoline or any other fuel
not
recommended in the previous text on fuel. Costly repairs
caused by use
of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number
(VIN).

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right
(clockwise) until
you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. See “Malfunction Indicator Lamp” in
the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type,
it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
Checking Things Under the Hoc4
m-
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.

Downloaded from www.Manualslib.com manuals search engine When to Add Oil
If the oil is at or below the ADD line, 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.
What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the
oil has been certified by the American
Petroleum Institute (APT).
Do not use any oil which
does
not carry this Starburst symbol.
~ NOTICE:
~~ ~~~ ~~~~~~~
~
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.
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. 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:
