1996 CHEVROLET EXPRESS Owners Manual

Downloaded from www.Manualslib.com manuals search engine While refueling, hang the cap inside the fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise).
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and
is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right until
you hear at least three clicks. 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.
I 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 or have proper
venting, and your fuel tank and emissions system
might
be damaged.
Checking Things Under the Hood

this handle inside the
vehicle. It is just in front of

Downloaded from www.Manualslib.com manuals search engine If your vehicle has a 7.4L engine and air conditioning,
your vehicle will have
a auxiliary engine fan in addition
to the belt driven fan.
A CAUTION:
If your vehicle has air conditioning, the auxiliary
engine 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.
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.
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.

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:
