Priming the 7.8L Isuzu 6H Diesel Engine
If your vehicle is equipped with the 7.8L Isuzu 6H
diesel engine, use the following procedure to
prime the engine:
1. Make sure there is fuel in the fuel tank.
2. Make sure the specified fuel filter is properly
installed.
3. Make sure the fuel lines are securely
connected.
4. Make sure the fuel filter is cool to the touch.
5. Use a clean cloth to remove dirt and oil
from the fuel filter head and breather valve.6. Use the palm of your hand to repeatedly
press and release the plunger (1) at the
top of the fuel filter priming pump. Continue
until the plunger resistance becomes firm. This
may take from 20 to 100 times, depending
upon fuel tank location.
7. Turn the fuel filter breather valve screw (2)
counterclockwise several turns to open the
breather valve.
8. Use the palm of your hand to repeatedly
press and release the plunger (1) at the
top of the fuel filter priming pump until fuel
begins to seep from the breather valve.

Fuel Filter Replacement
If you want to change the diesel engine fuel filter
yourself, here is how to do it:
{CAUTION:
Diesel fuel is ammable. It could start a
re if something ignites it, and you could
be burned. Do not let it get on hot engine
parts, and keep matches or other ignition
sources away.
First, drain any water from the filter by following
the water draining procedure earlier in this section.
Your vehicle’s engine should be off until the end
of this procedure.
If your vehicle has the 6.6L engine, the fuel filter is
located in the engine compartment on the
driver’s side of the vehicle. If your vehicle has
either the 7.2L or 7.8L engine, the fuel filters are
located in the engine compartment on the
driver’s side of the vehicle, and on the driver’s
side frame rail in front of the fuel tank.
1. Apply the parking brake.2. Unplug the water
sensor wire
connected to the fuel
filter and unscrew
the filter element.
3. Remove the filter element. If there is any dirt
on the filter sealing surface, clean it off.
Remove and reuse the water sensor float
switch located on the bottom of the fuel filter.
4. Install the new filter element.
5. Reinstall and tighten the filter container and
reconnect the water sensor wire to the filter.
6. Use the fuel filter priming procedure earlier in
this section to prime the fuel filter.
7. Tighten the air bleed valve by turning it
clockwise until hand-tight.
8. Start your engine and let it idle for
five minutes. Check your fuel filter and air
bleed valve for leaks.

Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be
hard to find. Never use leaded gasoline or any other
fuel not recommended in the previous text on fuel.
Costly repairs caused by use of improper fuel would
not be covered by your warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business
in the country where you will be driving.
Filling the Tank
{CAUTION:
Fuel vapor is highly ammable. It burns
violently, and that can cause very bad
injuries. Do not smoke if you are near
fuel or refueling your vehicle. Keep
sparks, ames and smoking materials
away from fuel.
The fuel cap can be on either or both sides of
your vehicle depending on option content.
To take off the cap, turn it slowly counterclockwise.
Fuel caps for all
gasoline applications,
and all diesel between
frame rail fuel tank
applicationsFuel caps for all side
mounted diesel
applications
264

{CAUTION:
If you get fuel on yourself and then
something ignites it, you could be badly
burned. Fuel can spray out on you if you
open the fuel cap too quickly. This spray
can happen if your tank is nearly full, and is
more likely in hot weather. Open the fuel
cap slowly and wait for any “hiss” noise to
stop. Then unscrew the cap all the way.
When you put the cap back on, turn it clockwise
until it is tight.
Notice:If you need a new fuel cap, be sure to
get the right type. Your dealer can get one
for you. If you get the wrong type, it may not
t properly. This may cause your malfunction
indicator lamp to light and may damage
your fuel tank and emissions system. See
Malfunction Indicator Lamp on page 174.If you have dual tanks, fill the driver’s side tank, or
forward tank, first. The fuel gage will give better
readings this way. Your gage will show the
total fuel left in both tanks.
If your vehicle is a C4/C5 model and you have
dual tanks, the engine must be off when refueling
or the fuel transfer system may become
inoperable.
If you have a single tank with dual fillers, where
there is a filler on each side of the vehicle, do not
attempt to fill the tank through both fillers at the
same time. Also, do not fill the tank with both caps
removed, as this may result in over-filling the
tank and fuel spillage.

{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
1. You can remove the
coolant surge tank
pressure cap when
the cooling system,
including the coolant
surge tank pressure
cap and upper
radiator hose, is no
longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn. If you hear a hiss, wait
for that to stop. A hiss means there is
still some pressure left.2. Then keep turning the pressure cap slowly,
and remove it.
3. Fill the coolant surge tank with the proper
mixture, to the FULL COLD mark.

To change an empty ether cylinder, follow
these steps.
1. Loosen the screw head on the
cylinder-to-bracket clamp.
2. Spread the clamp apart.
3. Clean any dirt from the neck of the cylinder
and the top of the valve before you take out
the cylinder.
4. Check the inside of the valve for any foreign
matter. Clean the valve as necessary.
5. Cover the valve to protect it from dirt and take
out the cylinder.
6. Install a new gasket whenever you take out
the cylinder. Use only one gasket and spread
a light film of clean oil on it before installation.
7. Put in the new cylinder. Turn it clockwise until
it just starts to contact the gasket.
8. Tighten the cylinder another half turn
(180 degrees). Don’t over-tighten.
9. Retighten the cylinder clamp.Front Wheel Bearings with
Oil-Filled Hubs
Notice:If you drive your vehicle through deep
water that is higher than the front or rear
axle, water may enter the axle housing and
cause the axle lubricant to break down.
This could damage the gears inside. Avoid
driving your vehicle through deep water.
You should avoid driving your vehicle through
deep puddles or standing water. If you must drive
through water that is higher than the front or
rear axle, see your dealer immediately afterward
to have the condition of the axle lubricant checked.

Tightening the Wheel Nuts
{CAUTION:
Wheel nuts that are not tight can work
loose. If all the nuts on a wheel come off,
the wheel can come off the vehicle,
causing a crash. All wheel nuts must be
properly tightened. Follow the rules in this
section to be sure they are.
This section lets you know how often to check the
tightness of the wheel nuts on your vehicle and
how tight they must be.
First, use these pictures to decide what kind of
wheels you have.Then, refer to the following steps for the wheels
you have.
Hub-Piloted Wheels, 8-Hole or 10-Hole
The studs and nuts used with these wheels have
right-hand threads.
1. With intermittent pilot pads, position a pad at
12 o’clock to center the wheel and reduce
run-out.
2. Put the tire and rim assembly on the axle hub.
Install the outer rear tire and rim assembly so
that its valve stem is exactly opposite the
valve stem on the inner tire and rim assembly.
