When to change spark plugs and rotor contacts?
It is recommended to replace distributor cap and rotor at the same time you are having the spark plugs and spark plug wires replaced. The cap and rotor contacts will wear down just like the spark plug electrodes wear down over time from the high voltage going through the electrodes.
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.
How does the distributor rotor and cap work?
The distributor rotor and cap keep the distributor’s contents separate from the engine and keep the distributor’s working parts clean and tidy – while supporting the incredibly high volts of energy and delivering them to the appropriate spark plugs. The spark plugs utilize the spark from the distributor to ignite the fuel mixture,…
What causes a spark plug to wear out?
Like all moving parts, distributor caps and rotors eventually wear out from a combination of heat, vibration, extreme voltage, cracking and carbon deposits and need to be replaced. These factors cause the plastic in the cap to break down over time and the internal plug wire contacts to oxidize and deteriorate from spark arcing.

Do you need to replace spark plug wires?
Damage: It’s possible for spark plug wires to be damaged. If the insulation is compromised, or there’s an internal break, you’ll need to replace your wires even if it’s not yet time.
Do you need an ohmmeter for spark plugs?
You’ll need an ohmmeter for this, and you’ll need to know what the wires’ original resistance was. Test each wire and look for resistance levels higher than when originally installed, as well as higher resistance in individual wires (which indicates a failed wire).
Why do spark plugs wear out over time?
And, just like your plugs, the wires wear out over time. Once they begin to wear, the electrical charge sent to the spark plugs can be unreliable, which creates problems with engine operation, including rough idling, stalls, and other issues.
Where is the distributor cap on a spark plug?
Start by removing the distributor cap. This is a big round part where all four spark plug wires are connected. The distributor cap is located in the front or at the top of the engine. It is held in place tightly by two latches. Remove the latches using a screwdriver. At this point, use a marker to make two lines.
What’s the best way to replace a spark plug?
An easier method to do this is to replace the spark plug wires, one at a time. Pull the old one from the spark plug and the distribution cap and replace it with a new one. Repeat the step for all 4 cylinders. This method is extremely simple, and you will not have to remove the distributor cap.
How do you know which spark plug wire goes where?
It is the same as the firing order of the engine. This answers how do you know which spark plug wire goes where. An easier method to do this is to replace the spark plug wires, one at a time. Pull the old one from the spark plug and the distribution cap and replace it with a new one.
What are the wires in a spark plug?
If playback doesn’t begin shortly, try restarting your device. An error occurred. Please try again later. (Playback ID: Fh4Yj_S4A4J_R5g_)
Why do spark plugs wear down over time?
The cap and rotor contacts will wear down just like the spark plug electrodes wear down over time from the high voltage going through the electrodes. You could have a mechanic like one from YourMechanic come to you and perform all the tune up work for you.
