If confused now just use this on your plug boots...
The page has changed recently, but it used to specify that it was ONLY to be applied where the rubber boot contacted the porcelain plug - NOT on any plug/wire metal, or on any electrical connector or terminal.
the reason coils go out is spark plugs are ignored and as the gap increases the potential the coil has to generate becomes larger and larger and that stresses them over time. Change your spark plugs more often and youll save your coils.
that may be the main reason that they ‘actually fail’. But IMO the most common reason that they are replaced (if talking about oem quality coils) is lack of test work. Oem coils typically don’t fail, but boots/springs do.
Dirt has high resistance to water & heat; so do red silicone, ceramic paint, Aluminum, & vulcanized rubber. And just like dielectric grease, they are all NOT suitable for coating electrical connectors.
It would be interesting to see where Ford specifies certain compounds in the workshop manuals or elsewhere.
My 2003 workshop manual has no references to Electrical Grease. XG-3 Caliper and Dielectric Grease is in it, but no XG-12. No reference to any grease at all in the electrical sections, except for Ignition. And one mention about using dielectric grease for protection of the starter S terminal from corrosion.
Not arguing, I'd just like to see where Ford specifies it. Inside the cabin, in the engine bay, everywhere? How long has it been around?
Funny, but the label on the tube actually seems more informative than Motorcraft's web pages.
The back of the XG-3-A tube is more informative also. Really don't understand why Motorcraft's web site is so poor. A person can learn more looking at labels on eBay listings.
IDK why it's so surprising that the LABEL is the best source of how to use anything. That's why labels exist - they're what's easiest to read when you're about to actually use something. IDK why more people don't READ labels more often. Have you ever read all the labels on your truck? Or its owner's manual cover-to-cover? There are about 3 pages in mine describing nearly EVERY chemical that should be used on it, and WHERE each one should be used, and HOW OFTEN.
Nice rant, but it's OFF-TARGET. You don't seem to understand how the internet is used today.
How would I see the label unless I travel to a store that has the Motorcraft product? And why would I travel to the store to look at the label, the instructions on the back, unless I had some idea of the purpose of the product. It's a chicken-egg thing. Am I supposed to travel to the store and read all of the labels? Why does Motorcraft put text on their web page that does not match the label, the instructions on the back? Because it's a poor web site.
Where is the specification for this electrical grease in the workshop manual? If the product has been around since the '80's why did Ford not specify it in my 2003 Workshop Manual? They specified the caliper and dielectric grease. So they were AWARE.
