If you want to change the fuel filter yourself, here's how to do it:
Caution: Diesel fuel is flammable. It could start a fire
if something ignites it, and you could be burned. Do not let it get on hot engine
parts, and keep matches or other ignition sources away.
First, drain any water from the filter following the procedure for draining
water listed previously.
The vehicle's engine must be off until the end of this procedure.
The fuel filter is located in the engine compartment on the passenger side of
the vehicle.
- Apply the parking brake. Access the fuel filter through the passenger
side wheel house opening. It is not necessary to remove all of the wheel liner fasteners.
- Remove only the necessary fasteners to allow the rear of the wheel liner
to be lowered enough for fuel filter access.
- Unplug the water sensor wire connected to
the fuel filter and unscrew the filter element.
- Remove the filter element. If there is any dirt on the filter sealing
surface, clean it off. Remove and reuse the water sensor float switch located on the
bottom of the fuel filter.
- Install the new filter element.
- Reinstall and tighten the filter container and reconnect the water sensor
wire to the filter.
- Reposition the wheel liner.
- Install and tighten fasteners.
- Use the fuel filter priming procedure earlier in this section to prime
the fuel filter.
- Tighten the air bleed valve by turning it clockwise until hand tight.
- Start the engine and let it idle for five minutes. Check the fuel filter
and air bleed valve for leaks.
- Reset the fuel filter monitor. See
DIC Warnings and Messages
for more information.
