When do you use Dielectric tune-up grease? Do I need to apply tad amount to the Coil?

[new2s5]

I use that stuff every where there is an electrical connection. I prefer the needle point tube.

[arjun90]

Are we suppose to use this when replacing the ignition coils?

[PaperToast]

I use that stuff every where there is an electrical connection. I prefer the needle point tube.

like he said, every electrical connection you find, use it.
last i checked, the coils are electrical . . .

[arjun90]

In what area on the Ignition Coil is the dielectric grease applicable to?

let me ask you, what looks like an electrical connection on the coil?

[arjun90]

The coil mediates the charge brought from the ignition coil harness into the spark plug. The ignition coil harness connector can be considered the origin and the spark plug as the insertion; no cliches here. Electricity is being passed into the connector of the ignition coil, following into where the coil inserts in the spark plug.

Is the dielectric grease applicable to where the connector inserts into the coil and / or the whole shaft of the coil / and or between the coil and spark plug only ? There are mixed comments, some saying that it will lead to stutter / misfires whereas others say is to keep the consistency of the flow of current. The grease acts as an insulator.

that is good info
the place to put the grease would be the connector to the coil, not the end that touches the spark plug

the whole point of dielectric grease is to moisture proof and help stop corrosion
ive put the grease in all the connectors i can get to in my engine bay with no ill affects.
the audi connectors are very well made and sealed to start, but every little bit helps

... The grease acts as an insulator.

Exactly! Any why would you want to smear part that acts as conductor with stuff that is an insulator? Air is a great insulator too, so you can as well disconnect your coil from the plug. One advantage of using air as insulator over insulating grease, is that it is plentiful and free.

"Dielectric grease is a non-conductive, silicone grease designed to seal out moisture and, therefore, prevent corrosion on electrical connectors. Being non-conductive, it does not enhance the flow of electrical current. This property makes it an ideal lubricant and sealant for the rubber portions of electrical connectors.

Dielectric grease is typically a translucent, grey substance that is insoluble in substances such as ethanol, methanol, mineral oil, and water. It is soluble, however, in the industrial solvent methyl ethyl ketone (MEK) and mineral spirit. It is important to note that dielectric grease will melt silicone rubber over time, and thus should not be used on connectors, such as o-rings, that are made of this rubber.

While the indicated use of dielectric grease calls for it to be used only on the non-metal parts of a connection, it has been shown to be effective at preventing corrosion when applied directly to the metal connectors as well. Care should be taken when using it in this way, because this application can, in some instances, cause the connection to stop working. A common reason for such a failure is that the grease has not been pushed entirely out of the way between the two points of contact.

Dielectric grease is most widely used as a sealant for spark plugs, and is applied to the rubber boot of the plug wire. The grease not only helps the boot slide onto the ceramic portion of the plug, but prevents dirt, moisture, sand, and other foreign objects from contaminating the seal, and compromising the electrical current. Dielectric grease is also commonly used on the gaskets of multi-pin connectors in car and marine engines.

It can withstand high temperatures, making it an ideal substance for use in engine compartments and other similar locations. Most standard brands of dielectric grease are rated to 392° F (200° C), and many can operate at up to 500° F (260° C).

Aside from sealing spark plugs, dielectric grease is often used to lubricate other engine-related parts, such as rotors, distributor caps, and speedometer cables. It is also employed in many other situations where electrical connections may be exposed to moisture and dirt. These can include outdoor lights, satellite television installations, trailer hitches, and battery terminals.

Dielectric grease protects electrical connections and wiring from salt, dirt and corrosion. Extends the life of bulb sockets. Prevents voltage leakage around any electrical connection. Also prevents spark plugs from fusing to boots. Required for modern high energy ignition systems."

hope this clears up any confusion; keep on wrenching

[arjun90]

Thanks PaperToast. I think what caused my confusion were the rubber boats. Our Audi's don't have the rubber boats per say. The closest to the Rubber boats are the ends of the Ignition Coils that insert onto to the Spark Plugs (could be analogous). Do correct me if I'm wrong, thanks again.

wish my audi came with a rubber boat...

[arjun90]

Well, yes, this is specific to the Ignition Coil and Spark Plug Setup on the C5's, not sure about older Audi vehicles.


Our CV Joints have rubber boats, completely different aspect.

[arjun90]

You apply dielectric grease to the head of the spark plug where the Ignition coil inserts to, just a tad thin layer,

As per,
http://www.audiworld.com/forums/a4-b...t-bww-2372612/

or within the bottom inside part of the coil as per,

https://snapguide.com/guides/change-...a5-all-b8-20t/

or

http://www.audizine.com/forum/showth...ug-Replacement

Do you all do the same, or is this procedure widely debated?

[julex]

Or you don't apply it at all. The way our igntion is designed, it actually seals at two points. First point is at top of coil to engine head, then the rubber boot to ceramic part of spark plug. As per excerpt above, you have to be careful with that stuff as all the seals used in connectors are actually rubber silicone and silicone grease damages them. With properly functioning connector there is zero need for grease though, probably why you won't see this stuff inside of factory connectors . Silicone grease is a great way to f.up otherwise well functioning electrical system if you have no practice using it. There is nothing like liberally spreading insulator over metal connectors and then counting on pressure/friction to push it out when you slide connectors over, yay!

It's odd that ECS Tuning includes dielectric grease in their Ignition Coil & Spark Plug kits, any idea why?
