80 - 28 IGNITION SYSTEMS
Hit
the distributor until achieving as close to 0° as pos­
sible. After adjustment, tighten clamp bolt to 22.5
N-m (200 in. lbs.) torque.
The degree scale on the SET SYNC screen of the
DRB is referring to fuel synchronization only. It is
not referring to ignition timing. Because of this,
do not attempt to adjust ignition timing using this
method. Rotating the distributor will have no effect
on ignition timing. All ignition timing values are con­
trolled by the powertrain control module (PCM).
IGNITION COIL—3.9L V-6 OR 5.2/5.9L V-8
ENGINES
The ignition coil is an epoxy filled type. If the coil
is replaced, it must be replaced with the same type.
REMOVAL
3.9L V-6 or 5.2/5.9L V-8 LDC-Gas Engines: The coil
is mounted to a bracket that is bolted to the front of
the right engine cylinder head (Fig. 14). This bracket
is mounted on top of the automatic belt tensioner
bracket using common bolts.
5.9L V-8 HDC-Gas Engine: The coil is mounted to a
bracket that is bolted to the air injection pump (AIR
pump) mounting bracket (Fig. 15).

(3) Remove ignition coil from coil mounting bracket
(two bolts).
INSTALLATION
(1) Install the ignition coil to coil bracket. If nuts
and bolts are used to secure coil to coil bracket,
tighten to 11 N-m (100 in. lbs.) torque. If the coil
mounting bracket has been tapped for coil mounting
bolts, tighten bolts to 5 N-m (50 in. lbs.) torque.
(2) Connect all wiring to ignition coil.
IGNITION COIL PICKS—8 J L ¥-11 ENGINE
REMOWAL
Two separate coil packs containing a total of five
independent coils are attached to a common mount­
ing bracket located above the right engine valve
cover (Fig. 16). The front and rear coil packs can be
serviced separately.
