Tools Required
J 43094 Spark Plug Boot Puller
Removal Procedure
- Remove the mounting nuts
retaining the injector sight shield.
- Lift the injector sight shield off the mounting studs by lifting
at the front (4) of the cover.
- Disconnect the electrical
connector from the ignition control module.
- Remove the 7 bolts (2) retaining the ignition cassette
to the cam cover.
Important: Do not insert the screwdriver far enough to tear the perimeter
seal on the cassette.
- Gently pry the cassette (2) away from the cam cover (3)
using a screwdriver. Protect finished surfaces from scratches with
a shop cloth. Pry a small amount in several locations around the edge
of the cassette in order to lift the assembly as evenly as possible.
- On some vehicles the oil level indicator tube may interfere with
the removal of the front bank coil cassette. Remove the bolt retaining the
oil level indicator tube and move the oil level indicator tube if
necessary.
- Lift the cassette straight up off the spark plugs.
- Remove the secondary boots (3)
from the spark plugs or the ignition coils using a twisting motion to break
the seal. Use theJ 43094
.
Do not use pliers, screwdrivers, or any unauthorized tool to remove the
boots.
- Remove the cover (4) from
the ignition coils (3).
- Remove the ignition control module retaining screws (1).
- Remove the ignition control module (2).
Installation Procedure
Important: When servicing the ignition system components, use the following recommended
procedures:
• | Do not re-install any component that has visible signs of damage. |
• | Check the boots for a missing or damaged internal spring. |
• | Ensure that the boots are installed right-side up. |
• | Ensure that the ignition cassette-to-cam cover ground spring (2)
is in place. |
• | Repair a torn perimeter seal with an RTV sealant. |
• | Clean all the mounting surfaces before re-installing any components. |
- Install the ignition control
module (2) on the ignition coils.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the ignition
control module retaining screws (1).
Tighten
Tighten the retaining screws to 1.1 N·m (10 lb in).
- Install the cover (4) on the ignition coils (3).
- Install the boots (3)
on the ignition coils until boots bottom out.
- Install the cassette assembly (2)
straight down onto the spark plugs.
If this is not possible due to space limitations (rear bank), just-start
the boots onto the spark plugs and then align and start the ignition coil
towers into the boots. Press the ignition cassette (2) down
on the plugs as straight as possible.
- Install the 7 bolts (2)
that retain the ignition cassette to the cam cover .
Tighten
Tighten the bolts to 9.5 N·m (84 lb in).
- Connect the electrical connector to the ignition control module.
- If the oil level indicator tube was moved during disassembly,
move the tube back into position and install the retaining bolt.
Tighten
Tighten the retaining bolt to 9 N·m (80 lb in).
- Keeping the injector sight
shield as level as possible, place the rear (1) of the shield under
the mounting bracket (6).
- Align and press the injector sight shield (4) onto the
mounting studs (5).
- Install the mounting nuts (2) onto the mounting studs (5).
Tighten
Tighten the mounting nuts to 3 N·m (27 lb in).
