What is a distributor rotor?
The distributor rotor is a small metal arm or connector that sits on top of the distributor shaft nestled safely under the distributor cap. The distributor shaft is rotated by the engines crankshaft and then subsequently causes the rotor to spin under the cap. The rotor is also connected to the ignition coil. When the coil delivers spark, it goes directly to the rotor and the rotor passes the spark by moving close to each connector rod for each cylinder. It passes by close enough without touching to where the current will jump across the gap to power the plug wires and then the plugs.
What can go wrong with a distributor rotor?
A rotor will face similar wear and tear seen in all ignition parts, such as the distributor cap. The rotor typically becomes corroded from moisture, chemicals, or other emissions. It can also shake loose or become warped from engine vibration. Rotors can get dirty and stop spinning or even break if they get stuck for some reason.
How do I know if I have a faulty distributor rotor?
There are signs that will alert you that you may have a bad, worn, or faulty distributor rotor. The most frequently seen sign is misfiring when sending spark to the valves. This causes very rough idle, hesitant acceleration, and possible backfires. A bad rotor can also ground out and steal some of your ignition spark making it completely impossible to start your vehicle. As with other distributor problems, keep an eye out for these things already mentioned along with dimmer lights, a malfunctioning radio, slower power windows or seats, and hesitation whenever RPM's are being driven higher.
Can I replace my distributor rotor?
You sure can. Depending on your make, model, and year vehicle, access to the distributor and the rotor can be the toughest part and what makes people take their car to the local dealership or mechanic. If you do have access, be sure to unhook your battery so no one gets cooked while removing parts or touching wires. Once the battery is disconnected, then remove the fasteners on the distributor cap. They are typically two small L-shaped rods that have a screwdriver head on the top with a spring underneath to keep them tightly secure. You need to suppress the rods from the top with a screwdriver and then turn them to free the cap from its grip. Once the cap is off, then there should be a couple of guide screws that need to be detached to remove the rotor and replace it with another.
Do new cars have distributor rotors?
Most likely, a new car will not have a traditional distributor rotor. Today's cars have coils attached individually to each spark plug or spark plug wire. This sends spark directly to the plugs and allows the firing order to be controlled by the car's ECU thus removing the need for a rotor that is driven by physical properties like the camshaft rotation, electrical current, and air vacuum.
