408 SERVICING AND MAINTENANCE
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
DRAINING FUEL/WATER SEPARATOR
F
ILTER — DIESEL ENGINE
There are two fuel filter assemblies. One is
located on the driver's side of the engine. The
best access to this water drain valve is from
under the hood. The second one is on the under
body, located in front of the rear axle above the
drive shaft on pick-up models. The Chassis Cab
models second filter location is on the frame
behind the front axle. The best access to this
water drain valve is from under the vehicle.
If water is detected in the water separator while
the engine is running, or while the ignition
switch is in the ON position, the “Water In Fuel
Indicator Light” will illuminate and an audible
chime will be heard five times. At this point you
should stop the engine and drain the water from
both of the filters.
If the “Water In Fuel Indicator Light” comes on
and a single chime is heard while you are
driving, or with the ignition switch in the ON
position, there may be a problem with your
water separator wiring or sensor. See an
authorized dealer for service.
Upon proper draining of the water from both
fuel filters, the “Water In Fuel Indicator Light”
will remain illuminated for approximately
10 seconds. If the water was drained while the
engine was running, the “Water In Fuel Indicator
Light” may remain on for approximately three
minutes.
NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the environ-
ment. Contact an authorized dealer, service
station, or government agency for advice on recy-
cling programs and for where used fluids and
filters can be properly disposed of in your area.
Drain the fuel/water separator filters when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the
engine mounted filter drain valve (located on
the side of the filter assembly)
counterclockwise 1/4 turn, and turn the under
body mounted filter drain valve (located on the
bottom of the filter assembly) counterclockwise
wise 1 full turn. Then turn the ignition switch to
the ON position, and allow any accumulated
water to drain. Leave the drain valve open until
all water and contaminants have been
removed. When clean fuel is visible, close the
drain valve following these guidelines:
1. Rotate the drain clockwise to close until
you feel resistance from the internal seal.
2. Continue turning the drain 1/2 of a turn to
properly compress the seal.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
CAUTION!
If the “Water In Fuel Indicator Light” remains
on, DO NOT START the engine before you
drain water from the fuel filters to avoid
engine damage.
