1997 CHEVROLET ASTRO check engine light

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.

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need
to add some lubricant. Add enough lubricant
to raise
the level to the bottom of the filler plug hole. Refer to the Maintenance Schedule to
determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL
J engine coolant. This coolant is designed
to remain in your vehicle for 5 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, see “Engine Overheating”
in
the Index.
A 50/50 mixture of water and DEX-COOL@ coolant for
your vehicle
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.
0 Let the warning lights and gages work as they should.

Downloaded from www.Manualslib.com manuals search engine Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to
go on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due
to heavy
snow, etc., the wiper will stop until
the motor cools. If
the overload is caused by some electrical problem and
not snow, etc., be sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load
is too heavy, the circuit breaker opens and closes,
protecting the circuit
until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance
of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
Spare fuses and a fuse puller are located in the
underhood electrical center. You can remove fuses with
the fuse puller. Remember to replace
any of the spare
fuses
you use, so you will have some if you ever need
them again.
If you ever have a problem on the road and don’t have
a spare fuse,
you can “borrow” one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is
in the engine compartment.

Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. If your vehicle has a built-in child
restraint, also periodically make sure the harness straps,
latch plates, buckle, clip, retractors and anchorages are
working properly. Look for
any other loose or damaged
safety belt and built-in child restraint system parts. If
you see anything that might keep a safety belt or built-in
child restraint system from doing its job, have it
repaired. Have any
torn or frayed safety belts or harness
straps replaced.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn
or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in the Index. Check
the transmission fluid
level; add if needed. See
“Automatic Transmission’’ in the Index.
A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service

specified in
Part D.

door and rear compartment hinges, latches and locks
