2-68 Fuel Gage
Gasoline Engine Diesel Engine
Your fuel gage will be on the right side of your
instrument cluster if your vehicle doesn't have the
optional tachometer. If you have a tachometer, your
fuel gage is on the lower left portion of your
instrument cluster.When the ignition is on, your fuel gage lets you know
about how much fuel you have left. When the gage first
shows empty, you'll still have a little fuel left, but you
should get more fuel soon.
If your vehicle has dual fuel tanks, the reading on the
gage is the average of the two tanks.
Here are four concerns of some operators. None of these
shows a problem with your fuel gage:
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.
At the gas station, the pump shuts off before the gage
reads full.
It takes a little more or less fuel to fill up than the
gage indicated.
If you have a diesel engine, also see your Caterpillar
Operation & Maintenance Manual.

2-70 Filterminder Gage (Diesel Engine)
This optional gage is in the
lower center of the
instrument panel. It
monitors the engine
air filter.
As the filter gets dirty, the yellow indicator will begin to
rise. When it reaches 25 inches of vacuum on the scale,
the filter should be replaced.
After replacing the filter, reset the gage by pressing in
the yellow reset pin at the bottom of the gage.
If you have a diesel engine, also see your Caterpillar
Operation & Maintenance Manual.
Hourmeter Gage (If Equipped)
If your vehicle has this
gage, it will be to the lower
left of the steering column,
mounted on a bracket either
above or below the fuse
block. It shows the total
engine operating time.

5-29 How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, but the coolant level
isn't at the COLD ADD mark or higher, add a 50/50
mixture of clean, drinkable water and coolant at the
coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before you do it. (See the Caterpillar
Operation &
Maintenance Manual for the proper engine coolant to use.)
CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap, is hot. Wait for the cooling system
and coolant surge tank pressure cap to cool if you
ever have to turn the pressure cap.

Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM
-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to use the proper service manual. It tells you much
more about how to service your vehicle than this manual
can. To order the proper service manual, see ªService
and Owner Publicationsº in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See ªMaintenance Recordº in the Index.
CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.

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
contribute to clean air. General Motors recommends that
you use these gasolines, particularly 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.
Diesel Fuel Requirements and
Fuel System
Diesel Engine Fuel
See your Caterpillar Operator & Maintenance Manual
for information concerning fuel usage.
Water in Fuel
Sometimes, water can be pumped into your fuel tank
along with your diesel fuel. This can happen if a service
station doesn't regularly inspect and clean its fuel tanks,
or if it gets contaminated fuel from its suppliers.
If this happens, water must be drained. Your dealer can
show you how to do this.
CAUTION:
Diesel fuel containing water is still flammable.
You could be burned. If you ever try to drain
water from your fuel, keep sparks, flames and
smoking materials away from the mixture.

Then place the prop rod,
located on the panel, where
the arrow is pointing.
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 or access panels, be sure all the
filler caps are on properly.
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 lbs. (4 536 kg). The Maintenance Schedule
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.

Engine Oil
(Caterpillar Diesel Engines)
See your Caterpillar Operation & Maintenance Manual
for information on oil quality and viscosities as well as
the temperature range chart.
Air Filter Restriction Indicator
Your engine has an indicator that lets you know when
the air filter is dirty and needs to be serviced. It is in the
air intake tube below the air cleaner on the passenger's
side of the engine.
When the yellow indicator
reaches the red ring in the
sight glass, it's time to
service the air filter.After the air filter is properly serviced, the indicator can
be reset by pushing the button on top of the indicator.
Engine Air Cleaner/Filter
Your GM Maintenance Schedule says when to replace
the air filter.
