360SERVICING AND MAINTENANCE
When inspecting accessory drive belts, small
cracks that run across ribbed surface of belt from
rib to rib, are considered normal. These are not a
reason to replace belt. However, cracks running
along a rib (not across) are not normal. Any belt
with cracks running along a rib must be replaced.
Also have the belt replaced if it has excessive wear,
frayed cords or severe glazing.
Accessory Belt (Serpentine Belt)
Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between two
ribs)
Belt slips
Groove jumping (belt does not maintain correct
position on pulley)
Belt broken (identify and correct problem before
new belt is installed)
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation)
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
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 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.
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 appropriate
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.
