How to Replace the Ignition Coil in a Dodge Caravanby Contributor
The 3.0L engine in a Dodge Caravan uses a distributor system that includes an ignition coil. This ignition coil converts power from the battery into a charge to trigger the spark plug wires. Other models with different engine types use a distributorless ingition system with an ignition coil pack.
Remove the Caravan Ignition Coil
Look under the hood for a distributor. The spark plug wires connect into the distributor cap. If you don't see a distributor, you may have a model with a distributorless ignition system.
Find the ignition coil. On a Dodge Caravan, the ignition coil is at the back of the intake manifold. Disconnect the negative battery cable to prevent injury while you work.
Determine whether you need to remove the windshield wiper/motor module assembly. This won't be necessary on all models.
Disengage the connector securing the wiring harness connector to the Dodge Caravan ignition coil. Then, disconnect the ignition wire from the ignition coil.
Use a socket set to remove the mounting bolts. There are upper and lower mounting bolts. Separate the ignition coil from the mounting bracket.
Install the New Ignition Coil
Insert the new ignition coil. Mount the Dodge Caravan ignition coil to the mounting bracket.
Attach the mounted assembly to the intake manifold. With a Torque wrench, tighten the fasteners securing the ignition coil to the mounting bracket with 96 inch pounds of torque (10 Nm).
Tighten the bolts that secure the intake manifold to the bracket with 115 inch pounds of torque (13 Nm).
Connect the wire harness and any other parts you removed, including the negative battery cable.
