Chrysler Repair: Chrysler 3.2/3.5L spark plug change, spark coil, coil assembly


Question
3.5 litre 2000 series. after taking out the two screws that hold the coils down do the coils come off easily or are they twisted down ? is the spark plug any special plug for this car?

Answer
Hi Robert,
Here is the description from the manual:
Spray compressed air around the spark coil and spark plug to remove any debris in the area of the plug socket
Remove electrical connector
Loosen the screws by alternating back and forth. Do not lose the spacers under the coil when loosening the screws. Remove fasteners.
Remove the ignition coil assembly
It would appear that they are not twisted down.
The spark plugs are platinum resistor plugs
I believe the plug is RC12PEC5 and the gap is .048 to .053 (1998 manual) or ZFR5LP-13G (2004 manual)
When removing spark plug boot, turn it 1/2 turn and then pull it off.
Tighten plugs to 20 foot-pounds. The screws for the coil are tightened to 60 inch-pounds (5 foot-pounds)
