and studs. Tighten the mounting bolts to 12 Nꞏm
(105 in.lbs.), using the sequence above.
6. Lower the transmission onto the crossmember.
Install nuts, and tighten.
7. Lower the engine into mounts using special tool #
8534.
8.For 2WD vehicles,Install both the left and right
side engine mount through bolts. Tighten the nuts
to 68 Nꞏm (50 ft. lbs.).
9.For 4WD vehicles,Install both the left and right side engine mount bracket to mount bolts. Tighten the nuts to
68 Nꞏm (50 ft. lbs.).
10. Remove special tool # 8534.

PUMP - ENGINE OIL
DESCRIPTION
The lubrication system is a full flow filtration pressure feed type.
Page 1884 of 5267
REMOVAL
1. Remove the oil pan and pick-up tube (Refer to 9 - ENGINE/LUBRICATION/OILPA N - R E M O VA L ) .
2. Remove the timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) -
REMOVAL).
3. Remove the four bolts, and the oil pump.
CLEANING
1. Wash all parts in a suitable solvent.
Page 1885 of 5267

INSPECTION
CAUTION: Oil pump pressure relief valve and
spring should not be removed from the oil pump.
If these components are disassembled and or
removed from the pump the entire oil pump
assembly must be replaced.
1. Remove the pump cover.
2. Clean all parts thoroughly. Mating surface of the oil
pump housing should be smooth. If the pump cover
is scratched or grooved the oil pump assembly
should be replaced.
3. Slide outer rotor into the body of the oil pump.
Press the outer rotor to one side of the oil pump
body and measure clearance between the outer
rotor (2) and the body. If the measurement is
0.235mm (0.009 in.) or more the oil pump assem-
bly must be replaced.
4. Install the inner rotor in the into the oil pump body.
Measure the clearance between the inner (3) and
outer rotors (1). If the clearance between the rotors
is .150 mm (0.006 in.) or more the oil pump
assembly must be replaced.
5. Place a straight edge (1) across the body of the oil
pump (between the bolt holes), if a feeler gauge (2)
of .095 mm (0.0038 in.) or greater can be inserted
between the straightedge and the rotors, the pump
must be replaced.
6. Reinstall the pump cover. Torque fasteners to 15
Nꞏm (132 in. lbs.).
NOTE: The 5.7 Oil pump is released as an assem-
bly. There are no DaimlerChrysler part numbers for
Sub-Assembly components. In the event the oil
pump is not functioning or out of specification it
must be replaced as an assembly.
Page 1886 of 5267
INSTALLATION
1. Position the oil pump onto the crankshaft and install the 4 oil pump retaining bolts.
2. Tighten the oil pump retaining bolts to 28 Nꞏm (250 in. lbs.).
3. Install the timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMINGBELT / CHAIN COVER(S) - INSTAL-
LATION).
4. Install the pick-up tube and oil pan (Refer to 9 - ENGINE/LUBRICATION/OIL PAN - INSTALLATION).

MANIFOLD - INTAKE
DESCRIPTION
The intake manifold is made of a composite material and features long runners which maximizes low end torque.
The intake manifold uses single plane sealing which consist of eight individual press in place port gaskets to prevent
leaks.
DIAGNOSIS AND TESTING - INTAKE MANIFOLD LEAKAGE
An intake manifold air leak is characterized by lower than normal manifoldvacuum. Also, one or more cylinders may
not be functioning.
WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING. DO NOT STAND IN ADIRECT LINE
WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR THE FAN. DO NOT WEAR
LOOSE CLOTHING.
1. Start the engine.
2. Spray a small stream of water at the suspected leak area.
3. If a change in RPM is observed the area of the suspected leak has been found.
4. Repair as required.
REMOVAL
1. Disconnect negative cable from battery.
2. Remove resonator assembly and air inlet hose.
3. Disconnect electrical connectors for the following components:
Manifold Absolute Pressure (MAP) Sensor
Intake Air Temperature (IAT) Sensor
Throttle Position (TPS) Sensor
Coolant Temperature (CTS) Sensor
4. Disconnect brake booster hose and positive crankcase ventilation (PCV)hose.
5. Remove generator and set aside.
NOTE: It is not necessary to remove lines or remove freon from A/C compressor.
6. Remove air conditioning compressor and set aside..
7. Bleed fuel system (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY - STANDARD PROCEDURE).
8. Remove intake manifold retaining fasteners in a crisscross pattern starting from the outside bolts and ending at
themiddlebolts.
9. Remove intake manifold and IAFM as an assembly.
CLEANING
NOTE: There is NO approved repair procedure for the intake manifold. If severe damage is found during
inspection, the intake manifold must be replaced.
Before installing the intake manifoldthoroughly clean the mating surfaces. Use a suitable cleaning solvent, then air
dry.
Page 1888 of 5267
INSPECTION
1. Inspect the intake sealing surface for cracks, nicks and distortion.
2. Inspect the intake manifold vacuum hose fittings for looseness or blockage.
3. Inspect the manifold to throttlebody mating surface for cracks, nicks and distortion.
INSTALLATION
1. Install intake manifold seals.
2. Position intake manifold and IAFM.
3. Install intake manifold retaining bolts, and tighten in sequence from the middle bolts towards the outside in a
crisscross pattern. Torque fasteners to 12 Nꞏm (105 in. lbs.).
4. Connect electrical connectors for the following components:
Manifold Absolute Pressure (MAP) Sensor
Intake Air Temperature (IAT) Sensor
Throttle Position (TPS) Sensor
Coolant Temperature (CTS) Sensor
Idle Air Control (IAC) Motor
5. Install generator.
6. Install A/C compressor.
7. Connect Brake booster hose and Positive crankcase ventilation (PCV) hose.
8. Install resonator assembly and air inlet hose.
9. Connect negative cable to battery.
