How do i change the fuel filter in my 2006 Jeep Liberty CRD?

Answer 1

FUEL FILTER NOTE: Capture all fuel in approved and appropriately marked containers. Wear safety goggles and adequate protective clothing when servicing the fuel system. # Disconnect the negative battery cable. # Disconnect the water in fuel (WIF) sensor wiring harness connector. # Drain the fuel filter/water separator (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY - STANDARD PROCEDURE). # Unscrew the filter assembly from the head assembly by rotating the housing counterclockwise. # Separate the WIF sensor and seal from the housing by rotating counterclockwise # Lubricate the fuel filter seal with clean diesel fuel. Pour the old diesel from the old filter into the new filter to minimize the size of the air pocket making priming much easier later.

# Install the water in fuel (WIF) sensor hand tight (FUEL FILTER/WATER SEPARATOR). # Screw filter assembly onto the fuel filter/water separator head. Tighten filter to 18 N·m (159 in. lbs.) (FUEL FILTER/WATER SEPARATOR). # Connect the WIF wiring harness connector. # Prime the fuel system (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY - STANDARD PROCEDURE). # Start the engine and allow to warm. # Turn engine off and inspect for leaks. WARNING: Store fuel in approved and properly marked containers. Wear safety goggles and adequate protective clothing when servicing fuel system. # Disconnect the negative battery cable. # Disconnect the water in fuel (WIF) wiring harness connector located under the fuel filter (FUEL FILTER/WATER SEPARATOR). # Connect a drain hose to the WIF sensor. # Place the other end of the drain hose in a approved and properly marked container. # Open the bleed screw on top of the fuel filter housing. # Loosen the WIF sensor on the bottom of the fuel filter to begin draining. # Allow the filter to drain into the container until fuel is visible. # Tighten the WIF sensor, remove the drain hose and clean any spillage. # Tighten the bleeder screw on top of the fuel filter housing. # Connect the WIF wiring harness connector. # Connect the negative battery cable. CAUTION:Cranking the engine for an extended period with out a fuel supply may result in damage to the high pressure fuel pump. DO NOT force the plunger when priming the fuel system. Damage to the plunger or fuel filter/water separate will result. NOTE:Should the vehicle run out of fuel, the fuel system must be re-primed in order to start. Factors such as temperature, how long the vehicle has been sitting, and engine cranking speed will influence how quickly the engine starts. If the water in fuel light is illuminated in the instrument panel, refer to the water in fuel sensor for draining procedure. The fuel system must be primed if the fuel system has been serviced. This is done using the fuel primer button located at the top of the fuel filter/water separator. # With service completed on the fuel system.

# Depress the fuel primer (2)(FUEL SYSTEM PRIMER) 20 consecutive times then open the bleeder screw on top of the housing to dispel trapped air. # Close the bleeder screw and continue the step above until the primer button becomes slightly harder to depress. # Turn the ignition to START and crank the engine a maximum of ten seconds. Engine cranking should be minimal (less than 1-2 seconds) if fuel from old filter has been used to fill up air pockets in new filter.

NOTE: If the engine does not start with in ten seconds, repeat the priming procedure. The engine will typically start within ten seconds; the engine may idle, idle rough, or stall, purging any trapped air from the lines and filter. # Tighten bleeder screw to 10.8 N·m (96 in.lbs.).
