If you notice arcing sounds or a burning smell, it may indicate that the dielectric grease has broken down and the connections need to be cleaned and re-greased. How to Apply to the Terminal Remove the spark plug wire boot carefully.
Dielectric Grease for Spark Plug Wire Bonding: Essential Application Areas
As a best practice, reapplying a small amount of grease during a major tune-up, such as when replacing wires or the distributor cap, ensures optimal protection for the lifespan of the ignition components. Primary Application: The Terminal Connection The most critical location to apply dielectric grease is the metal terminal inside the rubber boot of the spark plug wire.
The Distributor Cap and Rotor: A Critical Zone Beyond the spark plug wire, the other crucial area where dielectric grease belongs is inside the distributor cap, specifically on the rotor and the terminals where the wires connect. This specific step is vital for preventing the terminal from seizing onto the contact, making future removal difficult without damaging the rubber boot.
