How do you change the distributor on a 1989 Caravan with a 3L engine?

To change the distributor on a 1989 Caravan with a 3L engine, first disconnect the battery and remove any components obstructing access to the distributor. Mark the position of the old distributor to ensure proper alignment, then disconnect the wiring harness and remove the hold-down bolt. Lift out the old distributor and install the new one, aligning it to the mark you made earlier, and secure it with the bolt. Finally, reconnect the wiring, reassemble any components you removed, and reconnect the battery.
