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
in Interior Trim.
- Remove air cleaner assembly. Refer to
Air Cleaner Assembly Replacement
.
- Remove the air intake resonator assembly.
- 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
in Interior Trim.
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
Engine Cover Replacement
in Interior Trim.
