CYLINDER BORE INSPECTION
The cylinder walls should be checked for out-of-
round and taper with Tool C-119 (Fig. 134). If the cyl-
inder walls are badly scuffed or scored, the cylinder
block should be rebored and honed, and new pistons
and rings fitted. Whatever type of boring equipment
is used, boring and honing operation should be
closely coordinated with the fitting of pistons and
rings in order that specified clearances may be main-
tained.Refer to Honing Cylinder Bores outlined
in the Standard Service Procedures for specifi-
cation and procedures.
Measure the cylinder bore at three levels in direc-
tions A and B (Fig. 134). Top measurement should be
10 mm (3/8 in.) down and bottom measurement
should be 10 mm (3/8 in.) up from bottom of bore.
For specifications, refer to Engine Specifications in
this section.
ADJUSTMENTS
ENGINE TORQUE STRUT ADJUSTMENT
The upper and lower torque struts need to be
adjusted together to assure proper engine positioning
and engine mount loading. Whenever a torque strut
bolt(s) is loosened, this procedure must be performed.
(1) Loosen the upper and lower torque strut
attaching bolt at the suspension crossmember and
shock tower bracket (Fig. 135).
(2) The engine position may now be adjusted by
positioning a suitable floor jack on the forward edge
of the transmission bell housing (Fig. 136).
NOTE: The floor jack must be positioned as shown
in (Fig. 136) to prevent minimal upward lifting of the
engine.(3) Carefully apply upward force, allowing the
upper engine to rotate rearward until the distance
between the center of the rearmost attaching stud on
the engine mount bracket (point ªAº) and the center
of the hole for the washer hose clip on the shock
tower bracket (point ªBº) is 119 mm (4.70 in.) (Fig.
137).
(4) With the engine held at the proper position,
tighten both the upper and lower torque strut bolts
to 118 N´m (87 ft. lbs.) (Fig. 135).
(5) Remove the floor jack.

CLEANING AND INSPECTION (Continued)

CAUTION: After removing the steering knuckle from
the ball joint stud, do not pull outward on the knuckle.
Pulling the steering knuckle outward at this point can
separate the inner C/V joint on the driveshaft. Refer to
FRONT DRIVESHAFTS in the DIFFERENTIAL AND
DRIVELINE group for further information.
NOTE: Use caution when separating the ball joint
stud from the steering knuckle, so the ball joint seal
does not get cut.
(6) Separate each ball joint stud from the steering
knuckle by prying down on lower control arm and up
against the ball joint boss on the steering knuckle
(Fig. 3).
(7) If the vehicle is equipped with a power steering
fluid cooler, remove the two screws securing the
cooler to the front suspension crossmember. They are
located behind the cooler and can be accessed from
above. Allow the cooler to hang out of the way.
(8) Using wire or cord, support and tie off the
power steering gear to the underbody of the vehicle,
so when the crossmember is lowered, the gear does
not fall away being held to the vehicle by only the
steering column coupler and the fluid hoses.
(9) Loosen and remove the four bolts attaching the
power steering gear to the front suspension cross-
member (Fig. 4). Remove the power steering gear
from the front suspension crossmember.
(10) Remove the bolt mounting the engine torque
strut to the right forward corner of the front suspen-
sion crossmember (Fig. 5).
NOTE: Before removing the front suspension
crossmember from the vehicle, the location of thecrossmember must be scribed on the body of the
vehicle (Fig. 9). Do this so that the crossmember
can be relocated upon reinstallation against the
body of vehicle in the same location as before
removal. If the front suspension crossmember is
not reinstalled in exactly the same location as
before removal, the preset front wheel alignment
settings (caster and camber) will be lost.
(11) Using an awl, scribe a line (Fig. 6) marking
the location of where the front suspension crossmem-
ber is mounted against the body of the vehicle.
(12) Position a transmission jack under the center
of the front suspension crossmember and raise it to
support the bottom of the crossmember.
(13) Loosen and completely remove the two front
bolts (one right and one left) attaching the front sus-
pension crossmember to the frame rails of vehicle.
The right side bolt can be viewed in the mounting
bolt figure (Fig. 5). The left side bolt is located in the
same location on the other side of the vehicle.
(14) Loosen the two rear bolts (one right and one
left) attaching the front suspension crossmember and
lower control arms to the body of the vehicle until
they release from the threaded tapping plates in the
body of the vehicle. Remove the rear bolts from the
body of the vehicle, but do not completely remove the
rear bolts because they are designed to disengage
from the body threads yet stay within the lower con-
trol arm rear isolator bushing. This allows the lower
control arm to stay in place on the crossmember. The
right side bolt can be viewed in the mounting bolt
figure (Fig. 5). The left side bolt is located in the
same location on the other side of the vehicle.
(15) Lower the front suspension crossmember.

DESCRIPTION AND OPERATION
FUEL REQUIREMENTS
OPERATION
Your engine is designed to meet all emissions reg-
ulations and provide excellent fuel economy and per-
formance when using high quality unleaded gasoline
having an octane rating of 87. The use of premium
gasoline is not recommended. The use of premium
gasoline will provide no benefit over high quality reg-
ular gasoline, and in some circumstances may result
in poorer performance.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued heavyspark knock at high speeds can cause damage and
immediate service is required. Engine damage result-
ing from operation with a heavy spark knock may
not be covered by the new vehicle warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
The American Automobile Manufacturers Associa-
tion, AAMA, has issued gasoline specifications to
define the minimum fuel properties necessary to
deliver enhanced performance and durability for your
vehicle. DaimlerChrysler Corporation recommends
the use of gasoline that meet the AAMA specifica-
tions if they are available.
PLFUEL SYSTEM 14 - 1

carbon monoxide emissions. The type and amount of
oxygenate used in the blend is important.
The following are generally used in gasoline
blends:
Ethanol- (Ethyl or Grain Alcohol) properly
blended, is used as a mixture of 10 percent ethanol
and 90 percent gasoline. Gasoline blended with etha-
nol may be used in your vehicle.
MTBE/ETBE- Gasoline and MTBE (Methyl Ter-
tiary Butyl Ether) blends are a mixture of unleaded
gasoline and up to 15 percent MTBE. Gasoline and
ETBE (Ethyl Tertiary Butyl Ether) are blends of gas-
oline and up to 17 percent ETBE. Gasoline blended
with MTBE or ETBE may be used in your vehicle.
Methanol- Methanol (Methyl or Wood Alcohol) is
used in a variety of concentrations blended with
unleaded gasoline. You may encounter fuels contain-
ing 3 percent or more methanol along with other
alcohols called cosolvents.
DO NOT USE GASOLINE CONTAINING
METHANOL.
Use of methanol/gasoline blends may result in
starting and driveability problems and damage criti-
cal fuel system components.
Problems that are the result of using methanol/
gasoline blends are not the responsibility of
DaimlerChrysler Corporation and may not be covered
by the vehicle warranty.
Reformulated Gasoline
Many areas of the country are requiring the use of
cleaner-burning fuel referred to asReformulated
Gasoline. Reformulated gasoline are specially
blended to reduce vehicle emissions and improve air
quality.
DaimlerChrysler Corporation strongly supports the
use of reformulated gasoline whenever available.
Although your vehicle was designed to provide opti-
mum performance and lowest emissions operating on
high quality unleaded gasoline, it will perform
equally well and produce even lower emissions when
operating on reformulated gasoline.
Materials Added to Fuel
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents of similar ingredients that can be harmful to
fuel system gasket and diaphragm materials.
FUEL DELIVERY SYSTEM
OPERATION
The fuel delivery system consists of: the electric
fuel pump, fuel filter/fuel pressure regulator, fuel
tubes/lines/hoses, fuel rail, fuel injectors, fuel tank,
accelerator pedal and throttle cable.A fuel return system is used on all models (all
engines). Fuel is returned through the fuel pump
module and back into the fuel tank through the fuel
filter/fuel pressure regulator. A separate fuel return
line from the engine to the tank is no longer used
with any engine.
The fuel tank assembly consists of: the fuel tank,
filler tube, fuel gauge sending unit/electric fuel pump
module, a rollover valve(s) and a pressure-vacuum
filler cap.
Also to be considered part of the fuel system is the
evaporation control system or Onboard Refueling
Vapor recovery (ORVR). This is designed to reduce
the emission of fuel vapors into the atmosphere. The
description and function of the Evaporative Control
System is found in the Emission Control Systems
section.
FUEL PUMP MODULE
DESCRIPTION
The fuel pump module is installed in the fuel tank
(Fig. 1).
OPERATION
The fuel pump module contains the following:
²Electric fuel pump
²Fuel pump reservoir
²Inlet strainer
²Fuel filter/pressure regulator
²Fuel gauge sending unit
²Fuel supply line connection

PLFUEL SYSTEM 14 - 3
DESCRIPTION AND OPERATION (Continued)

The inlet strainer, fuel pressure regulator and fuel
level sensor are the only serviceable items. If the fuel
pump requires service, replace the fuel pump module.
ELECTRIC FUEL PUMP
DESCRIPTION
The electric fuel pump is located in and is part of
the fuel pump module. It is a positive displacement,
gerotor type, immersible pump with a permanent
magnet electric motor. The fuel pump module is sus-
pended in fuel in the fuel tank.
OPERATION
The pump draws fuel through a strainer and
pushes it through the motor to the outlet. The pump
contains a check valve. The valve, in the pump out-
let, maintains pump pressure during engine off con-
ditions. The fuel pump relay provides voltage to the
fuel pump. The fuel pump has a maximum dead-
headed pressure output of approximately 880 kPa
(130 psi). The regulator adjusts fuel system pressure
to approximately 338 kPa (49 psi).
FUEL GAUGE SENDING UNIT
DESCRIPTION
The fuel gauge sending unit (fuel level sensor) is
attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a vari-
able resistor (track). The resistor track is used to
send electrical signals to the instrument cluster for
fuel gauge operation and are then transmitted to the
engine controller for OBDII emission requirements.
OPERATION
For fuel gauge operation:As fuel level
increases, the float and arm move up. This increases
the sending unit resistance, causing the fuel gauge to
read full. As fuel level decreases, the float and arm
move down. This decreases the sending unit resis-
tance causing the fuel gauge to read empty.
After this fuel level signal is sent to the instru-
ment cluster, the instrument cluster will transmit
the data across the J1850 bus circuit to the PCM.
For OBD II emission requirements:The voltage
signal is sent to the instrument cluster to indicate
fuel level. The cluster transmits the fuel level to the
PCM where it is used to prevent a false setting of
misfire and fuel system monitor trouble codes. This
occurs if the fuel level in the tank is less than
approximately 15 percent of its rated capacity.
FUEL FILTER/FUEL PRESSURE REGULATOR
DESCRIPTION
A combination fuel filter and fuel pressure regula-
tor is used on all gas powered engines. It is located
on the top of the fuel pump module. A separate frame
mounted fuel filter is not used.
OPERATION
Fuel Pressure Regulator Operation:The pres-
sure regulator is a mechanical device that is cali-
brated to maintain fuel system operating pressure of
approximately 338 kPa (49 psi) at the fuel injectors.
It contains a diaphragm, calibrated springs and a
fuel return valve. The internal fuel filter (Fig. 2) is
also part of the assembly.
Fuel is supplied to the filter/regulator by the elec-
tric fuel pump through an opening tube at the bot-
tom of filter/regulator.
The fuel pump module contains a check valve to
maintain some fuel pressure when the engine is not
operating. This will help to start the engine.
If fuel pressure at the pressure regulator exceeds
approximately 49 psi, an internal diaphragm closes
and excess fuel pressure is routed back into the tank
through the pressure regulator. A separate fuel
return line is not used with any gas powered engine.
FUEL TANK
OPERATION
All models pass a full 360 degree rollover test
without fuel leakage. To accomplish this, fuel and
vapor flow controls are required for all fuel tank con-
nections.
All models are equipped with either one or two
rollover valves mounted into the top of the fuel tank
(or pump module).
An evaporation control system is connected to the
rollover valve(s) to reduce emissions of fuel vapors
into the atmosphere. When fuel evaporates from the
fuel tank, vapors pass through vent hoses or tubes to
a charcoal canister where they are temporarily held.
When the engine is running, the vapors are drawn
into the intake manifold. Certain models are also
equipped with a self-diagnosing system using a Leak
Detection Pump (LDP). Refer to the Emission Control
System for additional information.
FUEL RAIL
DESCRIPTION
The fuel rail supplies the necessary fuel to each
individual fuel injector and is mounted to the intake
manifold (Fig. 3).

DESCRIPTION AND OPERATION (Continued)

ROLLOVER VALVES
DESCRIPTION
All vehicles have rollover valve(s) on top of the fuel
tank.
OPERATION
The valves prevent fuel flow through the fuel tank
vent valve hoses should the vehicle rollover.
The rollover valves on the fuel tank are not ser-
viceable.

Also refer to Quick-Connect Fittings.
WARNING: THE FUEL SYSTEM IS UNDER A CON-
STANT PRESSURE (EVEN WITH THE ENGINE OFF).
BEFORE SERVICING ANY FUEL SYSTEM HOSES,
FITTINGS OR LINES, THE FUEL SYSTEM PRES-
SURE MUST BE RELEASED. REFER TO THE FUEL
SYSTEM PRESSURE RELEASE PROCEDURE IN
THIS GROUP.
Inspect all hose connections such as clamps, cou-
plings and fittings to make sure they are secure and
leaks are not present. The component should be
replaced immediately if there is any evidence of deg-
radation that could result in failure.
Never attempt to repair a plastic fuel line/tube.
Replace as necessary.
Avoid contact of any fuel tubes/hoses with other
vehicle components that could cause abrasions or
scuffing. Be sure that the plastic fuel lines/tubes areproperly routed to prevent pinching and to avoid heat
sources.
The lines/tubes/hoses used on fuel injected vehicles
are of a special construction. This is due to the
higher fuel pressures and the possibility of contami-
nated fuel in this system. If it is necessary to replace
these lines/tubes/hoses, only those marked EFM/EFI
may be used.
If equipped:The hose clamps used to secure rub-
ber hoses on fuel injected vehicles are of a special
rolled edge construction. This construction is used to
prevent the edge of the clamp from cutting into the
hose. Only these rolled edge type clamps may be
used in this system. All other types of clamps may
cut into the hoses and cause high-pressure fuel leaks.
Use new original equipment type hose clamps.
Tighten hose clamps to 3 N´m (25 in. lbs.) torque.
