1. Disconnect the battery ground cable.
2. Remove the RH side of the cowl vent screen, and cowl top extension.
3. Disconnect engine control sensor wiring from the ignition coil.
Remove the four ignition coil hold-down screws, and remove the ignition
coil to access the spark plugs on cylinders 1, 2 and 3.
4. Disconnect the electric IMRC actuator electrical connector. Remove
the mounting screws, and lay the IMRC actuator aside to access the spark
plugs on cylinders 4, 5 and 6.
5. Disconnect ignition wires from spark plugs:
-Disconnect ignition wires from spark plugs by grasping the ignition
wire spark plug boot and twisting slightly in both directions to free
it. CAUTION: Do not pull on the ignition wire as it may separate from
the connector inside the ignition coil boot.
-Disconnect the ignition wires from the ignition coil by squeezing the
locking tabs and twisting while pulling upward.
-Open ignition wire separators and remove ignition wire.
6. Loosen spark plugs 1/4 turn. Using compressed air, remove any dirt or
foreign material from spark plug areas of valve cover.
7. Note: Mark location of each spark plug for installation.
Remove spark plugs.
8. Check/adjustreplace spark plugs.
1. Follow removal procedure in reverse order.
2. Tighten spark plugs to 9-20 N-m (80-177 lb-in).
A)CAUTION: Proper installation of ignition wires is critical to vehicle
operation. If one ignition wire is not properly installed on spark plug
or ignition coil, both spark plugs connected to that ignition coil may
not fire properly.
B)Whenever an ignition wire is removed for any reason from a spark plug
or ignition coil, or a new ignition wire is installed, coat the entire
interior surface of the spark plug and ignition coil boot with Ford
Silicone Brake Caliper Grease and Dielectric Compound D7AZ-19A331-A
(Motorcraft WA-10) or equivalent meeting Ford specification ESE-M1C171-A
prior to installation using a small, clean tool.
C)Install each ignition wire to the proper terminal on the ignition
coil. The terminals on the ignition coil are numbered. Make sure the
ignition coil boots are fully seated and that both ignition coil boot
locking tabs are engaged.
D)Route ignition wire through ignition wire separators and close
ignition wire separators.
E)Connect ignition wires to spark plugs.
Its simple really, you just have to do it by "feel" A good ratchet with
a flex handle and a very short extension(like 1") should do the trick.
It sometimes helps to lay down on the engine to reach where you need to.
Good luck :)
Uhhh,no... "No@no" Have you done plugs on THIS engine??
Trainfan1's directions are correct for the 3.0 DOHC...and it really
doesn't take that long. Once you remove the cowl piece you get good
access to the rear plugs...and I found you DO need to remove the coil
to get to the front plugs.
