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 Regal Ignition Coil

The Buick Regal Ignition Coil is a small and vital part that has an enormous impact on the part of the car's working. Turning the low voltage from the battery into high voltage power, the ignition coil is capable of establishing the spark that would ignite the fuel in the combustion chambers of the engine. In this process, 12 volts of electricity are stepped up to a range of 15,000- 40,000 volts, sufficient to make the spark plug electrodes to bridge the gap with a view of igniting the fuel-air mixture. Ignition coil is made with windings wrapped around an iron core with primary winding and secondary winding, housed in a plastic, epoxy or polymer material. Originally, the Buick Regal's distributor ignition system used a set of ignition coils that are placed in the distributor cap While, more recent models of Buick Regal have incorporated the use of COP ignitions and also CNP ignitions too in some of their models. These coils are known to fail randomly or, degrade over time due to age and heat, shocks and vibrations and high resistance in spark plug cables. Thus, it is critical to maintain the ignition coils correctly and replace them if they become faulty in Buick Regal cars for the proper running of the machine and fuel economy.

Each OEM Buick Regal 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.
