Buick 19179578 Ignition Lock Cylinder

To replace the ignition control module on a vehicle, start by disconnecting the cable from the negative battery terminal. Then, access the distributor by removing the air filter assembly or the air intake duct and resonator, depending on the system. Next, remove the distributor cap and wires as an assembly, followed by the rotor. Carefully detach the wires from the module terminals and remove the screws to lift out the module. For 1988 through 1995 models, it is not necessary to remove the distributor from the engine. However, for 1996 through 2000 models, the ignition control module can be removed without removing the coil bracket. Once the module is removed, it can be tested with special equipment if there are suspicions of malfunction. To install the new module, apply silicone dielectric grease to the bottom of the ignition control module, as it dissipates heat and prevents overheating. Finally, reconnect the electrical connector and secure the module with mounting screws.
