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 illumi-
nate and an audible chime will be heard. At
this point, you should stop the engine and
drain the water from the filter housing.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filter to
avoid engine damage.
If the “Water In Fuel Indicator Light” comes
on and a single chime is heard while you are
driving, or with the ignition in the ON posi-
tion, there may be a problem with your water
separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from the
fuel filter, 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 approxi-
mately three minutes.
NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
where used fluids and filters can be properly
disposed of in your area.
Drain the fuel/water separator filter when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the
filter drain valve (located on the bottom of the
filter housing) counterclockwise to drain fuel/
water, 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 by turning it clockwise, and turn the
ignition switch to OFF.
If more than two ounces or 60 milliliters of
fuel have been drained, follow the directions
for “Priming If The Engine Has Run Out Of
Fuel.”

NOTE:
Using a fuel filter that does not meet the
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing a new fuel filter. There is a possibility
debris could be introduced into the fuel
filter during this action. It is best to
install the filter dry and allow the in-tank
lift pump to prime the fuel system.
