The distributor rotor fires the spark plug. If the rotor is damaged, it could cause harm to the car's engine. Knowing how to install a distributor rotor yourself can save you some money. Read on to find out how to install a new distributor rotor to the car.

Step 1 – Prep work

Park the car in a well lit area. Make sure that you are working in a clutter free environment. Wear your work gloves. Open the hood of the car.

Step 2 – Under the Hood

After opening the hood, the first step in installing the distributor rotor is to start by disconnecting the cable from the battery’s negative terminal. With the help of the wrench, loosen the bolt and remove the clamp.

Step 3 – Removing the Spark Plug

After having removed the clamp, proceed to pull out the spark plug. First mark the wires, then remove them from the cap. Now slowly take out the cap from the car's distributor.

Step 4 – Removing the Rotor

In this step, you need to dismantle the rotor from the distributor. With the help of a screwdriver remove the screws. This will free the rotor. Lift it from the shaft and take it out from the car.

Step 5 – Placing the Rotor

Check the new rotor and see if it is in a good condition. Now place the rotor in the shaft. The rotor can be installed in only one way. After placing the rotor, secure it with the screws.

Step 6 – Placing the Cap

In this step, you need to reintroduce the cap onto the distributor. A screwdriver will help you snap the cap into position. Make sure it rests correctly on the distributor.

Step 7 – Reconnecting the Wires

The wires that were taken off in Step 3 need to be reconnected. As they were marked, it becomes easier to plug the wires in the right slots. This connects it to the distributor.

Step 8 –   Reconnecting the Cable

Now you need to work in the reverse order. You need to reconnect the cable that was taken off in Step 2. This will reestablish the connection with the battery.

Step 9 – Caution

The spark plug has to be inserted in the right spots. This is the most crucial part in the installation of the distributor rotor. If not done accurately it will damage the engine.

Step 10 – Placing the Clamp

The clamp has to be fit back into position. Take the bolts that were removed and place them on the slots provided on the clamp. Use a wrench to tighten the bolts.

Step 11 – Final Step

Close the hood of the car. You might want to start up the engine after you have installed the distributor rotor.

Step 12 – Finishing Up

Take the vehicle out for a test drive. As a rule-of-thumb you might want to regularly check your vehicle for problems to ensure it stays in good condition.
