230 Driving and Operating
Running Out of Fuel
{
Warning
Diesel fuel is combustible. It could start a
fire if it gets on hot engine parts. You
could be burned. Catch any fuel from the
air bleed valve, and wipe up any spilled
fuel with a cloth.
If the engine has stalled due to running out
of fuel, try the following steps to restart it:
1. If parked on a level surface, add at least
7.6 L (2 gal) of fuel. Up to 18.9 L (5 gal)
may be needed if parked on a slope.
2. Follow the fuel priming procedure earlier
in this section to prime the fuel filter.
3. Turn the ignition key to START for 10 to
15 seconds at a time until the engine
starts. If the engine tries to run, but
does not run smoothly, increase the rpm
slightly by using the accelerator pedal.
This will help force air through the
system.
4. Return to Step 2 if the engine stalls and
will not restart.
5. After a few attempts, if the engine still
does not start, see your dealer.
Fuel Filter Replacement
{
Warning
Diesel fuel is flammable. It could start a
fire if something ignites it, and people
could be burned. Do not let it get on hot
engine parts, and keep matches or other
ignition sources away.
The fuel filter is on the driver side, inside
the frame rail.
To replace the fuel filter:
1. Drain any water from the filter. See
“Removing Water from the Fuel Filter” in
Water in Fuel 0 227.
Keep the engine off until the procedure
is completed.
2. Apply the parking brake.
3. Remove the filter element cap by turning
it counterclockwise.
4. Remove the filter element. If there is any
dirt on the filter sealing surface, clean
it off.
5. Install the new filter element and o-ring.
6. Reinstall and tighten the filter cap to the
housing.
7. Use the fuel filter priming procedure to
prime the fuel filter. See “Fuel Priming”
in Water in Fuel 0 227.
8. Start the engine and let it idle for
five minutes. Check the fuel filter and air
bleed valve for leaks.
