Dodge Ram Truck 1500-2500-3500. Manual — part 359

If cable tray removal is necessary, release the 4 tray-to-manifold retention clips.

8.3L - SRT-10

Failure to route the cables properly could cause the radio to reproduce ignition noise, cross ignition of the spark
plugs or short circuit the cables to ground.

1. Release the fuel pressure, refer to the Fuel Pressure Release procedure in the Fuel Delivery section.

2. Disconnect the negative battery cable.

3. Remove the air cleaner assembly, refer to the Engine/Air Intake section for more information.

4. Remove the Intake Manifold, refer to the Engine/Manifolds/Intake Manifold for more information.

5. Use the following procedure when removing the high tension cable from the spark plug. Grasp the terminal as

close as possible to the spark plug. Rotate the cover boot 1/2 turn slightly and pull straight up in a steady
motion.Do not use pliers and do not pull the cable at an angle. Doing so will damage the insulation, cable
terminal or the spark plug insulator. Wipe spark plug insulator clean before reinstalling cable.

6. Remove spark plug cable from coil first.

7. Always remove the spark plug cable by grasping the top of the spark plug insulator, turning the boot 1/2 turn and

pulling straight up in a steady motion.

INSTALLATION

INSTALLATION

Install cables into the proper engine cylinder firing order sequence. Refer to Specifications.

When replacing the spark plug and coil cables, route the cables correctly and secure them in the proper retainers.
Failure to route the cables properly may cause the radio to reproduce ignition noise. It could also cause cross-
ignition of the plugs, or, may short-circuit the cables to ground.

When installing new cables, make sure a positive connection is made. A snap should be felt when a good connec-
tion is made.

Failure to route the cables properly could cause the
radio to reproduce ignition noise, cross ignition of the
spark plugs or short circuit the cables to ground.

The system uses two epoxy filled coil packs mounted
on engine block post in the valley under the intake
manifold. The rear coil pack, contains 3 separate coils
and fires cylinders 1, 2, 3, 4, 6, and 7. The front coil
pack, contains 2 individual coils and fires cylinders 5,
8, 9, and 10.

NOTE: When replacing the spark plug and coil
cables, route the cables correctly and secure them
in the proper retainers. Failure to route the cables
properly may cause the radio to reproduce ignition
noise. It could also cause cross-ignition of the
plugs, or, may short-circuit the cables to ground.

1. Install wire separator clip on double ended stud on

rear of engine block first. This is the wire separator
clip closest to the ignition coil insulator boots.

2. Connector coil insulator boots over respective igni-

tion coil side post. Take care to match cylinder
number on ignition coil with cylinder number on
ignition cables. Also, make sure to hear the audible
click while making the connection to the coil post.

3. Sequentially install wires into separators clips

mounted on double ended studs mounted on the
outer side of valve cover and and. Start from the
rear and work forward to the front of the engine.

4. After installing all wires into separator clips, install

spark plug insulator boots over respective spark
plugs sequentially from back of engine towards the
front of engine. Make sure to hear the audible click
during installation of spark plug boots.

5. Install Intake Manifold, refer to the Engine/Mani-

folds/Intake Manifold for more information.

6. Install Air Cleaner Assembly, refer to the Engine/Air

Intake section for more information.

7. Connect the negative battery cable.

8. Use a diagnostic scan tool to pressurize the fuel

system. Check for leaks.
