What is a distributor?
The distributor, located inside the ignition system, distributes the high-voltage spark generated by the ignition coil and sends power to the right spark plug wires with the correct firing timing. The distribution process works in combination with the combustion process in the engine’s combustion cylinders, which ensures the engine runs efficiently.
When should I replace the distributor on my car?
If you notice any symptoms of a bad distributor, you should have it replaced immediately. The most common symptoms of a damaged or faulty distributor include:
Engine misfires or rough idling: If your vehicle jerks when starting, idling, or accelerating, there may be an issue with your distributor and the combustion process.
Vehicle won’t start: If your distributor is damaged, your spark plugs will not operate correctly and your car may not start.
Shaking or rough vibrations: A faulty distributor will impact the spinning motion of your distributor rotor, which can cause your car to shake or vibrate.
Check engine light: Your check engine light could indicate issues with your distributor. A mechanic can scan your vehicle for trouble codes to uncover why your check engine light is illuminated.
Strange noise: A clogged distributor will emit a high-pitched squealing noise.
High emissions: If your vehicle smells strongly of fuel or it fails an emissions test, it could be due to a faulty distributor.
Low fuel efficiency: A bad distributor can decrease your mileage and increase your vehicle’s fuel consumption.
Keep in mind: Signs of a bad distributor can vary from vehicle to vehicle. If you experience any of the symptoms listed above, check your owner’s manual for troubleshooting recommendations, or talk to a mechanic for professional guidance.
How often should a distributor be replaced?
Distributor assemblies do not have a general lifespan. In fact, distributors are typically made to last the lifetime of the vehicle. The only time a distributor should be replaced is if unusual symptoms are detected, and a replacement is deemed necessary after an inspection and diagnosis.
Can I replace my distributor myself?
Distributors are complex assemblies, consisting of numerous parts that require precise connections. While it’s possible to replace a distributor yourself, it’s best to seek the expertise of a professional mechanic.
