What are the Distributor Rotor and Cap all about?

When the engine is running, high voltage created by the ignition coil travels through the coil wire to the ignition rotor. As the ignition rotor turns in the distributor, the rotor distributes the spark by sending it in a synchronized order through the spark plug wires to the spark plug located in each of the engine's cylinders.

The distributor is a main component of the ignition system. It takes very high voltage and delivers it to fire the spark plugs.

Keep in mind:

When the distributor rotor and cap are replaced, the entire ignition system should be inspected.
After replacing the distributor rotor and cap, the ignition wires will need to be reinstalled.

How it's done:

Check the ignition system.
Replace the cap and rotor if found faulty.
Re-check the ignition system.
Check ignition timing if needed.

Our recommendation:

Whenever your vehicle has routine maintenance or servicing, the ignition system should be inspected thoroughly. If you ever notice your ignition system having a hard time (such as your car having trouble turning on or staying on), then you should schedule an inspection.

What common symptoms indicate you may need to replace the Distributor Rotor and Cap?

Engine misfires.
Car does not start.
Noises from the engine.
Check engine light is on.

How important is this service?

The distributor rotor and cap is used when the engine is running. During this time, high voltage is created by the ignition coil, and sent through the coil wire to the ignition rotor. This rotor turns inside the distributor, and as it does so, it evenly distributes sparks to the spark plugs, through the spark plug wires. The spark plugs then use this spark to ignite the fuel mixture, which allows the engine to keep running.

If the distributor rotor and cap malfunction, the voltage from the ignition coil won’t be redistributed to the spark plugs, and your engine will either have a hard time running, or won’t run at all.

GMC R3500 V8-5.7L - Brake System Inspection - Newark, New Jersey

Pretty good. My inspection for my brakes went very quick, (a little too quick.) Not the most thorough inspection. However, Tomas came to the same conclusion that I had already suspected and the problem is now "dually" analyzed. 15 minutes, and I'm good. Tomas was quite knowledgeable and polite. He came with the proper tools and equipment to say the least and was promptly on time for the booked appointment. I would consider requesting Tomas again for similar work. Thanks again to Tomas and the team at YourMechanic for helping out.

Excellent mechanic! Knows how to diagnose problems with older vehicles without relying on the computer giving him codes. He's managed to keep our old vehicles up and running which is great when you can't afford to buy a new vehicle.
