Here's a general procedure. Remember that specifics may vary slightly depending on the exact engine in your Dynasty (check your owner's manual for specifics). Always disconnect the negative battery terminal before starting any work on the ignition system.
Tools You'll Need:
* Socket wrench set (likely a 1/4" drive)
* Screwdriver (likely Phillips head)
* Pliers or needle-nose pliers
* New distributor rotor
* Shop rag or paper towels
Procedure:
1. Locate the Distributor: The distributor is usually located on the engine, near the top, and is connected to the ignition coil and the spark plug wires. Consult your owner's manual or a repair manual for the specific location on your Dynasty's engine.
2. Disconnect the Ignition Coil Wire: The wire from the ignition coil to the distributor cap should be easily disconnected. Carefully remove the wire and set it aside.
3. Remove the Distributor Cap: Carefully remove the distributor cap. Note the position of each spark plug wire so you can put them back in the correct order. Take a picture or draw a diagram if needed.
4. Remove the Rotor: The rotor is usually held in place by friction. Use pliers or needle-nose pliers to carefully grip the rotor and pull it straight up. It might be a little stiff, but it should come off relatively easily.
5. Install the New Rotor: Carefully align the new rotor with the distributor shaft. Make sure it sits squarely and firmly on the shaft. It should snap into place.
6. Reinstall the Distributor Cap: Carefully place the distributor cap back on, ensuring each spark plug wire is seated correctly in its terminal. Use your notes or picture as a guide.
7. Reconnect the Ignition Coil Wire: Reconnect the ignition coil wire to the distributor cap.
8. Reconnect the Battery: Reconnect the negative battery terminal.
Important Considerations:
* Timing: While replacing the rotor doesn't typically require adjusting the ignition timing, any significant distributor work could affect it. If your engine is running poorly after this repair, you might need to have the timing checked by a mechanic.
* Engine Type: Different engines may have slightly different distributor designs. Consult a repair manual specific to your 1989 Dodge Dynasty's engine for detailed instructions. You can often find these online (e.g., Haynes or Chilton manuals).
* Safety: Always disconnect the battery's negative terminal before working on the ignition system. This prevents accidental shocks or damage to the electronic components.
* Rotor Alignment: Ensure the rotor is properly aligned with the distributor shaft. Misalignment can lead to misfiring or engine damage.
This is a general guide; the specifics might differ for your specific engine. Consult a repair manual specific to your vehicle for detailed instructions and diagrams. If you are not comfortable performing this repair, take your vehicle to a qualified mechanic.
