5. Open the fuel filter vent
valve by turning the
screw counterclockwise
several full turns. The
vent valve is located
on top of the fuel filter
housing.
6. Repeatedly push down
on the fuel filter priming
pump with the palm of
your hand. The pump
is located on top of the
fuel filter housing. Let
the pump return upward
between pushes.7. Operate the priming pump until a small amount of
fuel seeps from the vent valve. When you see the
fuel, the filter is now full of fuel and the system
should be primed.
8. Close the vent valve. Clean any fuel which
accumulated on the fuel filter. Start the engine and
let idle for a few minutes. Check the filter for leaks.
Q:How do I prime the vehicle? (Van Models)
A:Your vehicle is equipped with an electric priming
pump which is located in front of the fuel tank
under your vehicle. The priming pump is operated
electrically and is designed to bring fuel to the engine
to eliminate any air that may be in the fuel lines.
To prime the engine, do the following:
1. Turn the ignition key on for two minutes. The fuel
pump will be operating and starting the priming
process. Do not start the engine during the first
two minutes.
2. After completing the initial prime in Step 1, turn the
ignition off, then back to start and crank the engine
for 15 seconds.
3. If the engine does not start, repeat Steps 1 and 2
until the engine starts.

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.9. Reset the fuel filter monitor. SeeDriver Information
Center (DIC) (Pickup Models Only) on page 3-9for
more information.

If your fuel operated heater (FOH) is not working, your
FOH line requires priming. See your dealer for service.
SeeFuel Operated Heater (FOH) (Van Models Only) on
page 2-8for more information.
If you want to change the fuel filter yourself, here’s 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 following the
procedure for draining water listed previously.
Your vehicle’s engine should be off until the end of this
procedure.
The fuel filters are located on the driver’s side frame rail
in front of the fuel tank.

To remove the fuel cap, turn it slowly to the left
(counterclockwise).
{CAUTION:
If you spill fuel 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.Be careful not to spill diesel fuel. Don’t top off or overfill
your tank, and wait a few seconds after you’ve finished
pumping before you remove the nozzle. Clean fuel from
painted surfaces as soon as possible. See “Washing
Your Vehicle” in your owner’s manual. When you put the
fuel cap back on, turn it to the right (clockwise) until you
hear a clicking sound. 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. SeeMalfunction
Indicator Lamp on page 3-4.

Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{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.
Park the vehicle on a level
surface. 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.
1. Turn the pressure cap slowly counterclockwise (left)
until it first stops. Don’t press down while turning the
pressure cap. If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure left.2. Then keep turning the cap, but now push down as
you turn it. Remove the pressure cap.
3. After the engine cools, open the air bleed valve on
the thermostat housing.
Fill with the proper mixture. Add coolant until you
see a steady stream of coolant coming from the
bleed valve.
4. Close the bleed valve.
5. Rinse or wipe the spilled coolant from the engine
and compartment.

{CAUTION:
You can be burned if you spill coolant on hot
components in the engine compartment.
Coolant contains ethylene glycol, and it will
burn if the engine parts are hot enough. Do not
spill coolant on a hot engine or components in
the engine compartment.
When the coolant in the coolant surge tank is at the
COLD FILL mark, start your vehicle.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,
up to the FULL COLD mark. SeeEngine Coolant
on page 5-34
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan. By this time, the coolant level inside the
coolant surge tank may be lower. If the level is lower,
add more of the proper mixture to the coolant surge
tank until the level reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
