1996 CHEVROLET EXPRESS oil level

Downloaded from www.Manualslib.com manuals search engine Oil Pressure Gage
The oil pressure gage
pressure
in psi (pounds
shows
the engine oil
per square inch) when the
engine is running. Canadian
vehicles indicate pressure
in kPa (kilopascals).
OIL 93
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low
oil level or other problem causing low
oil pressure. Check your oil as soon as possible.
A C -1TION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You
or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

you allow a reasonable following distance. Expect to
move slightly slower
at night.
When
you want to leave the freeway, move to the
proper lane well in advance. If
you miss your exit, do
not, under
any circumstances, stop and back up. Drive
on
to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer,
not
to your sense of motion. After driving for any distance
at higher speeds,
you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re
not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to
go. If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in GM
dealers all across North America. They’ll be ready and
willing to help
if you need it.
Here are some things
you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated
to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should
you delay your trip a short
time to avoid
a major storm system‘?
Maps: Do you have up-to-date maps?

Reduce speed and shift to a lower gear before you start
down
a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce
your
speed to around 45 mph (70 kdh) to reduce the
possibility
of engine and transmission overheating.
When towing at high altitude
on steep uphill grades,
consider the following: Engine coolant will boil
at a
lower temperature than at normal altitudes.
If you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar
to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission
in PARK (P) for a few
minutes before turning the engine off. If you do get the
overheat warning, see “Engine Overheating”
in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig
on a hill, here’s
how to do it:
1. ’ Apply your regular brakes, but don’t shift into
PARK (P) yet. Then turn your wheels into the curb
if facing downhill or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Re-apply the regular brakes. Then apply your
parking brake and then shift
to PARK (P).
5. Release the regular brakes.

When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine Fan(s)
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.
The coolant level should be at
or above the FULL
COLD mark.
If it isn’t, you may have a leak in the
radiator hoses, heater
hoses, radiator, water pump or
somewhere else in the cooling system.
5-12

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.
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 FULL COLD mark, add a 5060 mixture of
clean water (preferably distilled) and DEX-COOL’”
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant”
in the Index for
more information.)
Adding only plain water to your cooling sy,,,m
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
TM antifreeze.

If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
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.
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 Oil
If the oil is at or below the ADD mark, then you’ll need to
add some
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.
I NOTICE:
Don’t add too much oil. If’ your engine has so much
oil that the oil level gets above the upper mark that
shows the proper operating range,
your engine
could be damaged.

Downloaded from www.Manualslib.com manuals search engine What Kind of Oil to Use
The engine oil filler cap is located between the air
cleaner and engine oil dipstick.
Just 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. 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 (API).
Do not use any oil which
does not carry this Starburst symbol.
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:

When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle’s GVWR is over 8,600 or
if
the vehicle is mainly driven under one or more of
these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90°F (32°C) or
higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If your vehicle’s
GVWR is not over 8,600 and you do
not use your vehicle under any
of these conditions, the
fluid and filter do
not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
.Because this operation can be a little difficult, you
may choose to have this done at your GM dealer
Service Department.
If you do it yourself, be sure
to follow all the
instructions here, or you could get a false reading
on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission. Too much can mean that some of
the
fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission
fluid.
