410 SERVICING AND MAINTENANCE
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 envi-
ronment. 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 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.
NOTE:
Over-compression of the seal due to over-tight-
ening of the drain will damage the seal, cause a
leak, and require the entire sensor to be
replaced.
3. Turn the ignition switch to OFF.
The sensor drain should not be over-tightened
during normal service operations to avoid
internal damage and future fuel leaks. The
drain should be closed and secured without the
use of tools.
If more than a couple ounces/milliliters of fuel
have been drained, follow the directions for
“Priming If The Engine Has Run Out Of Fuel.”
