Some distributors may require partial disassembly in order to remove and replace the ignition module. Though most modules are replaceable without disassembling the distributor, removing the distributor assembly from the engine will make access to the components easier. If you wish to avoid removing the distributor from the engine, remove the cap and rotor to see if access to the module retainers and connectors is possible, then decide if you want to remove the distributor.

  1. Disconnect the negative battery cable.

  3. Remove the distributor cap and position aside with the wires attached.
