Removal Procedure
Notice: There are two procedures available to install the distributor.
Use Installation Procedure 1 when the crankshaft has NOT been
rotated from the original position.
Use Installation Procedure 2 when any of the following components
are removed:
• | The timing chain or sprockets |
If the malfunction indicator lamp (MIL) turns on and DTC P1345
sets after installing the distributor, this indicates an incorrectly installed
distributor.
Engine damage or distributor damage may occur. Use Procedure 2
in order to install the distributor.
- Turn OFF the ignition.
- Remove the engine cover. Refer to
Engine Cover Replacement
.
- Remove the spark plug wires from the distributor cap.
• | Twist each spark plug wire boot 1/2 turn. |
• | Pull only on the wire boot in order to remove the wire from the distributor
cap. |
- Remove the electrical connector from the base of the distributor.
- Remove the 2 screws that retain the distributor
cap to the housing.
- Discard the screws.
- Remove the distributor cap from the housing.
- Use a grease pencil in order to mark the position of the rotor in relation to
the distributor housing (1).
- Mark the distributor housing and the intake manifold with the grease pencil.
- As
the distributor is being removed from the engine, watch the rotor move in a counter-clockwise
direction about 42 degrees. This will appear as slightly more than one clock
position.
- Note the position of the rotor segment.
- Place a second mark on the base of the distributor (2). This will
aid in achieving the proper rotor alignment during the distributor installation.
- Remove the mounting clamp hold-down
bolt.
- Remove the distributor.
Installation Procedure 1
- If
installing a new distributor assembly, place 2 marks on the new distributor housing
in the same location as the marks on the original housing.
- Remove the new distributor cap, if necessary.
- Align the rotor with the second mark (2).
- Guide the distributor into the
engine.
- Align the hole in the distributor hold-down base over the mounting hole
in the intake manifold.
- As the distributor is being installed, observe the rotor moving in a clockwise
direction about 42 degrees.
- Once the distributor is completely seated, the rotor segment should be
aligned with the mark on the distributor base (1).
• | If the rotor segment is not aligned with the mark, the driven gear teeth
and the camshaft have meshed one or more teeth out of alignment. |
• | In order to correct this condition, remove and reinstall the distributor. |
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.
- Install the distributor mounting clamp bolt.
Tighten
Tighten the bolt to 25 N·m (18 lb ft).
- Install the distributor cap.
- Install the new distributor cap screws.
Tighten
Tighten the screws to 2.4 N·m (21 lb in).
- Install the electrical connector to the distributor.
- Install the spark plug wires to the distributor cap.
- Install the ignition coil wire. Note the
correct orientation of the wire boot.
Important: If the malfunction indicator lamp illuminates
after installing the distributor and DTC P1345 is set, the distributor has been installed
incorrectly.
- Refer to Installation Procedure 2 if the malfunction indicator lamp illuminates
after installing the distributor.
- Install the engine cover. Refer to
Engine Cover Replacement
.
Installation Procedure 2
Important: Rotate the number 1 cylinder to top dead
center (TDC) of the compression stroke. The engine front cover has 2 alignment tabs
and the crankshaft balancer has 2 alignment marks spaced 90 degrees apart which
are used for positioning the number 1 piston at TDC. With the piston on the compression
stroke and at TDC, the crankshaft balancer alignment mark (1) must align with
the engine front cover tab (2) and the crankshaft balancer alignment mark (4)
must align with the engine front cover tab (3).
- Rotate the crankshaft balancer clockwise until the alignment marks on the crankshaft
balancer are aligned with the tabs on the engine front cover and the number 1 piston
is at TDC of the compression stroke.
- Align the white paint mark on the bottom
stem of the distributor and the pre-drilled indent hole in the bottom of the gear (3).
Notice: The ignition system distributor driven gear and rotor may be installed
in multiple positions. In order to avoid mistakes, mark the distributor on
the following components in order to ensure the same mounting position upon
reassembly:
• | The distributor driven gear |
Installing the driven gear 180 degrees out of alignment, or locating
the rotor in the wrong holes, will cause a no-start condition. Premature
engine wear or damage may result.
- With the gear in this position, the rotor segment should be positioned as shown
for a V6 engine (1).
• | The alignment will not be exact. |
• | If the driven gear is installed incorrectly, the dimple will be approximately
180 degrees opposite of the rotor segment when installed in the distributor. |
- Use a long screw driver in order
to align the oil pump drive shaft to the drive tab of the distributor.
- Guide the distributor into the engine. Ensure the flat portion of the
distributor housing is facing toward the front of the engine.
- Once
the distributor is fully seated, the rotor segment should be aligned with the pointer
cast into the distributor base.
If the rotor segment does not come within
a few degrees of the pointer, repeat the procedure in order to achieve the proper
alignment.
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.
- Install the distributor mounting clamp bolt.
Tighten
Tighten the bolt to 25 N·m (18 lb ft).
- Install the distributor cap.
- Install the new distributor cap screws.
Tighten
Tighten the screws to 2.4 N·m (21 lb in).
- Install the electrical connector to the distributor.
- Install the spark plug wires to the distributor cap.
- Install the ignition coil wire. Note the
correct orientation of the wire boot.
Important: If the malfunction indicator lamp illuminates
after installing the distributor and DTC P1345 is set, the distributor has
been installed incorrectly.
- Repeat Installation Procedure 2 if the malfunction indicator lamp illuminates
after installing the distributor.
- Install the engine cover. Refer to
