Section 67 (5.7L Engine (Service Information)): Installation
New or remanufactured engines may come with the pilot bushing installed for the 8-speed transmissions. If the 8-speed pilot bushing is not needed it must be removed before engine installation.
If the original engine has experienced a catastrophic failure or an individual failure with the piston, cylinder bore, engine block, valve or valve seat, the intake manifold MUST be replaced with a new manifold.
Do not use air tools to install Engine Lift Fixture and Adapter (special tool #8984C, Fixture, Engine Lifting) (2, 3).
- Install the engine lift fixture (special tool #8984C, Fixture, Engine Lifting) (2) and adapter (special tool #8984-UPD, Adapter, Engine Lift) (4).
- Using a suitable engine hoist, lower the engine into in the engine compartment.
- Align the engine with the transmission.
- Install two transmission to engine block mounting bolts finger tight.
- Lower the engine assembly until the engine mounts rest in the engine cradle crossmember.
- Align the engine mounts, install both left and right engine mount to frame retaining bolts (2) and tighten to the proper torque specifications. Refer to (TORQUE SPECIFICATIONS ).
- Position both left and right engine mount heat shields (4), install the retaining nuts (3) and to tighten to the proper torque specifications. Refer to (TORQUE SPECIFICATIONS ).
- Remove the engine hoist and the jack supporting the transmission.
- Install the transmission to oil pan bolts (1) and to tighten to the proper torque specifications. Refer to (TORQUE SPECIFICATIONS ).
- Install the remaining transmission bell housing to engine block fasteners (2) and tighten to the proper torque specifications. Refer to (TORQUE SPECIFICATIONS ).
- Position the engine ground wire to the transmission and securely tighten the fastener (1).
- Position the engine harness (2) and securely tighten the fasteners (1) at the transmission bell housing.
- Connect the engine harness (1) to the Multiple Displacement Solenoid (MDS) solenoid wire harness connector.
- Connect the wire harness connectors (1) to the ignition capacitors.CAUTION:
It is essential that the correct length bolts are used to attach the converter to the flexplate. Bolts that are too long will damage the clutch surface inside the torque converter.
- Rotate the crankshaft in clockwise direction and install all torque converter to flexplate bolts (1) finger tight.
- Verify that the torque converter is pulled flush to the flexplate and tighten the bolts to the proper torque specifications. Refer to (TORQUE SPECIFICATIONS ).
- Install the inspection cover (1) and tighten the retaining bolt (2) to the proper torque specifications. Refer to (TORQUE SPECIFICATIONS ).
- Connect the CKP sensor wire harness connector (1).
- Install the starter. Refer to STARTER, INSTALLATION .
- If equipped with AWD, install the front axle assembly. Refer to INSTALLATION
.
- Position the catalytic converters (4) onto the exhaust manifold flanges, install the flange nuts (3) and tighten to the proper torque specifications. Refer to TECHNICAL SPECIFICATIONS .
- Connect the oxygen sensor wire harness connectors (2).
- Connect the right and left knock sensor (1) wire harness connectors (3).
- Install the heat shields onto both knock sensors (shield snaps on/off sensor).
- Remove the engine lift fixture (special tool #8984C, Fixture, Engine Lifting) (2) and adapter (special tool #8984-UPD, Adapter, Engine Lift) (4).
- Install the Variable Valve Timing Solenoid (VVTS). Refer to INSTALLATION
.
- Connect the heater hoses (1, 2).
- Connect the engine coolant temperature sensor wire harness connector (2).
