Removal Procedure
- Inspect
the distributor ventilation system for proper ventilation. Refer to Section 6E.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing
any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to
the vehicle or its components.
- Disconnect the negative battery cable.
- Raise the vehicle. Suitably support the vehicle. Refer to Section 0A.
- Disconnect the cooling fans electrical connectors.
- Remove the left cooling fan.
- Remove the accessory drive belt. Refer to
Drive Belt Replacement
in Engine Mechanical.
- Remove the crankshaft balancer. Refer to
Crankshaft Balancer Replacement
in Engine Mechanical.
- Drain the engine coolant from the engine. Refer to Draining and Filling Cooling System (5.7L VIN P)
in Engine Cooling.
- Lower the vehicle.
- Remove the air intake duct.
- Disconnect the intake air temperature (IAT) connector.
- Disconnect the upper and lower radiator hoses at the water pump and reposition.
- Disconnect the heater hoses at the water pump and throttle body.
- Disconnect the engine coolant sensor (ECT) electrical connector.
- Reposition the ignition coil and coil bracket.
- Remove the air pump and bracket.
- Remove the water pump. Refer to
Water Pump Replacement
in Engine Cooling.
- Raise the vehicle. Suitably support the vehicle. Refer to Section 0A.
- Remove the spark plug wire harness from the distributor.
| 19.1. | Twist the boot ½ turn before removing. |
| 19.2. | Pull only on the boot in order to remove the wire from the distributor. |
- Disconnect the distributor PCM connector.
Important: Do not allow foreign material to enter any
open vacuum lines. Cap the ends as necessary.
- Remove the distributor vacuum harness. Refer to Section 6E.
- Remove
the distributor mounting bolts.
- Remove the distributor. Pull the distributor forward until the coupling
disengages from the end of the camshaft.
Installation Procedure
Important: Do not attempt to fully seat the distributor
using bolts or screws. If the distributor does not seat by hand, then it is not properly
aligned with the camshaft.
- Install the distributor as follows:
| 1.1. | Rotate the crankshaft until the engine is at the number 1 cylinder TDC.
The camshaft sprocket pin is at the 9 o'clock position. |
| 1.2. | Rotate the distributor coupling until the camshaft sprocket pin slot aligns
with the distributor base timing mark. |
| 1.3. | Rotate the coupling until the camshaft sprocket pin slot aligns with the
pin. |
| 1.4. | Install the distributor. |
| 1.5. | Using hand pressure, slide the distributor onto the camshaft until the
distributor is fully seated. |
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
| 1.6. | Install the distributor bolts. |
