When replacing an ignition system, all components should be examined, including spark plugs, wires, distributor caps, and rotors. It is also advisable to check the serpentine belt system and tune the vehicle after replacing the ignition. Advances in manufacturing mean that replacements are less frequent.
To replace an ignition, it is imperative that all components be examined. If every part of the system is not inspected, it can lead to a vehicle that will not start even after replacing the ignition. Spark plugs, spark plug wires, distributor caps and rotors on equipped vehicles as well as points and any capacitors found in the distributor should also be changed when it is time to replace an ignition. On vehicles equipped with electronic ignition, it is also important to change the ignition module when making an effort to replace an ignition system.
The ignition in a vehicle is made up of several components. When replacing any part of the system, it is advisable to examine the rest of the system for signs of wear. Any change in the components can lead to a crash in the other components. Changing the spark plugs can lead to discovering that the spark plug wires should have been changed. This is why it is advisable to replace an ignition as a complete system.
Most US vehicles produced after 1995 do not require adjustment before the vehicle reaches 25,000 miles. Advances in spark plug manufacturing do not require the vehicle owner to replace the ignition as frequently as many owners believe the process is necessary. Engine efficiency and better fuel and oils have advanced to the point that vehicle engine components do not require maintenance as frequently. This includes engine oil changes, which many manufacturers now recommend no more than every six months or 5,000 miles.
To save on future repair work, it is advisable to check the serpentine belt system in the vehicle’s engine when an ignition replacement is planned. If there are signs of wear in the form of cracks or fraying along the edges of the belt, it should be replaced when the vehicle is scheduled to have the ignition replaced. This saves time, as many of the components that require removal to service the belts are also removed to replace an ignition. This also cuts the labor in half as the parts will be removed in any case.
A vehicle must also be tuned after its ignition components have been changed. Often the vehicle’s spark timing can be altered by fiddling with the spark plug wires and the distributor cap. This is not as common in distributorless ignition systems. However, it is always recommended that the vehicle be driven with caution for the first 50 to 100 miles after the vehicle owner’s decision to replace an ignition system. This allows the system to be examined for loose components after service.
