Fig. 30 Spark Plug Cable Order—8.0L V-10 Engine
When installing new cables, make sure a positive
connection is made. A snap should be felt when a
good connection is made between the plug cable and
the distributor cap tower.
On 3.9L V-6 or 5.2/5.9L V-8 engines, spark plug ca­
ble boot heat shields are pressed into the cylinder
head to surround each cable boot and spark plug
(Fig. 31). These shields protect the spark plug boots
from damage (due to engine heat generated by the
exhaust manifolds) and should not be removed. After
the spark plug cable has been installed, the lip of the
cable boot should have a small air gap to the top of
the heat shield (Fig. 31).
