Diesel Fuel-Water Separator
A diesel fuel-water separator separates the water nor-
mally found in diesel fuel. A manual hand prime pump is
located on the filter head for re-priming the fuel system.
The fuel-water separator is located on the driver side
cowl in the engine compartment. Refer to “2.8L Turbo
Diesel Engine Compartment” in Section 7 for location.
NOTE:If the “Water-In-Fuel Warning Light” (located in
the instrument cluster) comes on, this indicates that
water has collected in the fuel filter and should be
drained immediately. See your authorized dealer for
service.Should your vehicle run out of fuel, the fuel system must
be re-primed in order to start the engine. Factors such as
temperature, which affects the viscosity of the fuel, how
long the vehicle has been sitting and other factors will
influence how quickly the engine starts.
Re-Priming the Diesel Fuel System
The following procedure must be followed after com-
pletely running out of fuel.
1. Add a minimum of 2 gallons (7.57L) of diesel fuel to
the fuel tank.
2. Open the hood.

maximum of 10 seconds. If the engine does not start,
repeat Step 3.NOTE:The engine will typically start within 10 sec-
onds; the engine will idle then stall, purging air from the
fuel lines and filter.
5. Depress the fuel-water separator knob 20 consecutive
times.
6. Turn the ignition to START and crank the engine a
maximum of 10 seconds. The engine should start and
remain running.
NOTE:If the engine does not start, repeat the cycle as
many times as necessary.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord. The engine block
heater cord is found under the hood clipped to the heater
line on the left side of the engine (3.7L only).Hand Prime Pump
