Draining Fuel/Water Separator Filter - Diesel Engine - RAM 2500 2020 Owner's Manual

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 sepa-

rated 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 (note: 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.

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.
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.
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.
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.
