How to test and remove/install the Ignition Coil on Buick Century and Regal?

To test the Coil-In-Cap, start by removing the distributor cap and disconnecting the coil. Use an ohmmeter to check the resistance across the primary connections, ensuring it is close to zero. Then, test the resistance between the primary ground and the coil secondary connector, using both solid wire and dotted line connections. If the readings are infinite, the coil needs to be replaced. For a separately mounted coil, disconnect the secondary lead and unplug the primary leads. Remove the coil from the engine and use an ohmmeter to check the resistance on the high scale. It should be nearly infinite. Then, test the resistance on the low scale, which should be close to zero. Finally, reset the ohmmeter to the high resistance scale and check for continuity. If all three tests pass, the coil is satisfactory. To remove and install the coil-in-cap, mark the high tension wires and disconnect them from the distributor cap. Remove the cap by depressing and rotating the wire type latch. Turn the cap upside down and remove the four bolts holding the coil. Disconnect the primary wiring and remove the coil. Clean the mounting area and inspect the cap for defects before installing a new coil. For a separate cap, disconnect the negative battery cable and remove the secondary coil lead. Disconnect the harness from the coil assembly and remove the mounting screws. Install the new coil, reconnect the harness, and reattach the secondary lead. Finally, reconnect the negative battery cable.

Buick Century Ignition Coil

The Buick Century Ignition Coil is an essential part that operates an essential function of the automobiles; the ignition. The ignition coil in turn steps up the low voltage coming from the battery to produce high voltage power required tocause spark to ignite the fuel in the combustion chamber of the engine. This process entails conversion of electricity through the primary and secondary windings of coil to the 15,000- 40,000 volts needed to bridge the gap between the electrodes of a spark plug. Buick Century vehicles throughout the years have had a number of types of ignition coils some of which include distributor ignition systems, coil on plug ignition systems and coil near plug ignition systems. Different styles of ignition coils have many ways of distributing voltage to current spark plugs: some systems have one coil per cylinder. If the ignition coil is not working, no spark is produced and there will be no start or a weak, rough, and poor running engine. Maintenance of the ignition coil and its inspection should be done often so that the functions of the engine are not affected and there are no complications.

Each OEM Buick Century Ignition Coil we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
