1995 GMC SIERRA fuel cap

Listed are four situations you may experience with your f~~el gage:
At the gas station. the fuel pump shuts off before the gage reads full.
It lakes a little more or less fuel to fill up than the fuel gage indicated.
For example, the gage may have indicated the tank was half
full, but it
actually took a little more or less than half the tank's capacity to fill the
, tank.
The gage moves a little when you turn a corner or speed up.
The gage doesn't go back to empty when you turn off the ignition.
None of these indicate
a problem with the fuel gage.
For information on how to fill your fuel tank, see "Fuel - Filling Your
Tank"
in the Index.
For your fuel tank capacity, see "Fuel -Tank Capacity" in the Index.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. Most of the time. the gage
pointer
will show your coolant temperature at 2 10°F (99"C), or less. But, if
you are pulling a heavy load or driving LIP hills, your coolant temperature
may rise and
fall near the red 260°F ( 128°C) mark. This is normal. If the
gage pointer moves to the red 260°F
(128°C) mark, your engine is too hot!
It means that your engine coolant has overheated. You should pull off the
road,
stop your vehicle. and turn off the engine as soon as possible.
Hot Coolant Can Burn You Badly!
In "Problems on the Road," this manual shows what to do. See "Engine
Overheating"
in thc Index.

Loading Your Vehicle
-
DSI/KPA (COL3)
The Certification/Tire label is found on the rear edge of the driver’s door or
in the Incomplete Vehicle Document in the cab.
The label shows the size of your original tires and the inflation pressures
needed to obtain
the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The CertificatiodTire label also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR).
To find out
the actual loads
on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.
A CAUTION-:
In the case of a sudden stop or collision, things carried in the bed
of your truck could shift forward and come into the passenger \
area, injuring you and
others. If you put things in the bed of
your truck, you
should make sure they are properly secured.

Engines)” part, later in this section.
Install the fuel tank cap.
If the WATER IN FUEL light comes on again after driving a short distance
or the engine runs rough or stalls-a large amount of water has probably
been pumped into the
fuel tank. The fuel tank should be purged.

Fuels in Foreign Countries (Gasoline Engines)
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode,
and your engine
oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged.
All of that means costly repairs that 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).

Filling Your Tank
The fuel cap is behind
a hinged door on
the
left side of your
vehicle.
A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don’t smoke
if you’re near gasoline
or refueling your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.

While refueling, hang
the cap inside the fuel
door.
To take off the cap, turn it slowly to the left (counterclockwise).
-~
A CAUTION:
If you get gasoline on yourself and then something ignites it, you
could be badly burned. Gasoline can spray out on you if you
1 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.
When
you put the cap back on, turn it to the right until you hear a clicking
noise.
1 NOTICE:
If you need a new cap, be sure t.0 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.

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.
A CAUTION:
Things that burn can get on hot engine parts and start a fire.
These include liquids like gasoline or diesel fuel, 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 filler caps are on properly. Pull down
the
hood and close it firmly.
Cleaning Your Diesel Engine
I NOTICE:
If you spray or pour water or any other liquid on your engine
when it is warm or hot, or when it
is running, you could cause
serious damage to it.
If you ever clean the engine, clean it only
when it is cold.
Noise Control System
The following information relates to compliance with Federal noise
emission standards for vehicles with a Gross Vehicle Weight Rating
(GVWR)
of more than 10,000 pounds (4 536 kilograms). The Maintenance
Schedule booklet provides information on maintaining
the noise control
system to minimize degradation of the noise emission control system during
the life of your vehicle. The noise control system warranty is given in your
Warranty booklet.
These standards apply only
to vehicles sold in the United States.
