Fuel Filter - Chevrolet Low Cab Forward 2023 Manual

Fuel Filter

Change the fuel filter in accordance with the
Maintenance Schedule or when the fuel
filter indicator light (amber) comes on.
Drain the water when the water separator
(fuel filter) warning light comes on. (Drain
the water from the chassis-side fuel filter
and engine-side fuel filter.)
Failure to replace the fuel filter when
needed may lead to fuel system damage.
Your authorized dealer can inspect your fuel
filter and replace your fuel filter, if needed.
Water Separator
The purpose of the water separator is to
separate any water that may have formed
in the fuel tank due to condensation.
The water separator is located on the
bottom of the chassis side fuel filter.
Water Separator (Fuel Filter) Warning Light
When a certain amount of water has
collected in the water separator, the water
separator (fuel filter) warning light
comes on.
When this happens, drain the water and
make sure that the warning light has
gone out.
Vehicle Care
Remaining water that is not discharged from
the water separator could freeze and
damage the vehicle.
If the warning light comes on while the
engine is in operation, promptly drain the
water from the water separator (fuel filter).
Continuing to drive with the light remaining
on could damage the fuel injection system.
If this happens, have the vehicle checked
and serviced by the nearest dealer.
