When to replace distributor rotor and spark plug?
It’s also vital to take time to mark the location of the distributor, the distributor cap, spark plug wires and the rotor on the bottom of the distributor before it’s removed; and during the removal process. Failure to properly mark the wires and reinstall the new distributor cap exactly as the used one was removed can result in ignition problems.
How does a distributor rotor and cap work?
The coil supplies the power directly to the rotor and as the rotor spins, distributes this electricity to each cylinder by way of plug wires that are attached to the distributor cap. When the tip of the rotor passes a contact on the cylinder, the high voltage pulse goes from the coil to the cylinder through the rotor.
How do you change the cap on a distributor?
After the wires have been installed in the new cap, place the cap on the distributor and rotate it until the alignment tab allows the cap to drop into place. Reconnect the cap back to the distributor, and reconnect the short plug wire back to the ignition coil. Double-check all wire connections.
What can cause a distributor cap to fail?
In fact, as the image above indicates, there are several problems that can cause the distributor cap to fail including: Small cracks in the housing Broken spark plug wire tower Excessive carbon tracks embedded on the distributor cap terminal Burned distributor cap terminals

How do you remove a spark plug from a distribitor?
Wiggling and slightly twisting the wire boots while pulling upwards will aid in removal. It is a good idea to trace the spark plug wires from each cylinder back to the distributor cap when labeling the wires. Now that the spark plug wires and coil wire are removed from the distribitor cap, the cap can be removed from the distributor.
After the wires have been installed in the new cap, place the cap on the distributor and rotate it until the alignment tab allows the cap to drop into place. Reconnect the cap back to the distributor, and reconnect the short plug wire back to the ignition coil. Double-check all wire connections.
How do you replace a distributor cap and rotor?
Lift the old rotor off and install the new one making sure it is aligned the same way the old one was. While you have the rotor off, try moving the distributor shaft back and forth to check for any excessive lash or play in the shaft itself.
How often should a distributor cap be replaced?
During routine tune-ups, which happen every 25,000 miles, the distributor cap and rotor are often inspected for premature signs of wear and tear and will be replaced if they are damaged.

How do you replace a distributor spark plug?
Transfer spark plug wires one-by-one onto the new cap, following their location in the old cap as a guide and installing them in the same position in the new cap. Lift the old rotor off and install the new one making sure it is aligned the same way the old one was.

What are the symptoms of a broken distributor cap?
Some of the common symptoms of a damaged or broken distributor cap or rotor may include the following: The Check Engine Light is illuminated: The distributor cap and rotor are vital parts of the ignition system on most older vehicles on the road today.
