Dielectric grease?? Yes—No?

Dielectric grease?? Yes—No?

Postby Lee in Mountain View [OP] » June 4th 2020, 8:57pm

Folks, what’s the consensus on using dielectric grease for spark plug/spark plug wires? If you use it, do you apply to the spark plug wire contacts? I’ve only used it for light bulbs that’s why i ask.

Thanks.........Lee in Mountain View

Just keep in mind that 'Dielectric' grease is an insulator.
If you use it in a light bulb situation I am assuming you are trying use it to keep water out of the socket area, and/or reduce corrosion of the contacts.
It probably would not hurt anything in a physical contact like a plug wire connector or an electrical terminal, where there is a direct mechanical connection, but if there is any sort of a physical gap, it will act as an insulator, because that is just what it is. You need a solid electrical mechanical connection. Good quality lamp bases provide that, but corroded or old loose bayonet bulb bases may not.
Also, there are good products for helping park plug boots to release. After many mile in that environment, the boots often want to bond with the spark plug ceramic. The smallest tube will last a very LOOONG time.
YMMV

Dielectric grease will keep the boots from sticking to the spark plugs, easier to get off next time.Good plug wire sets even come with a package of it.
