DESCRIPTION AND OPERATION
FIRING ORDERÐ3.3/3.8L
The firing order for 3.3L and 3.8L engines is 1-2-3-
4-5-6.
REMOVAL AND INSTALLATION
SPARK PLUG CABLE SERVICEÐ3.3/3.8L ENGINES
WARNING: The ignition cables should not be
removed while the engine is hot. This could cause
sever injury/burns and can cause damage to the
ignition cables.
The spark plug boot heat shield needs to be
installed correctly on the boot before being installed
on the engine (Fig. 1). If it is not installed correctly
engine misfire would occur.
Do not use pliers to pull the boot/heat shield
assembly from the spark plugs. This will damage the
shield assembly.
Spark plug boot heat shields must be replaced if
they are bent or damaged. It is extremely important
the shield is reinstalled correctly as shown. The bot-
tom of the spark plug heat shield must make contact
with the spark plug socket hex.
