Dylectric grease
Well im about to go change the plugs on my 2001 2.5l and I wanted to know if dylectric (sp?) grease is really needed. I dont have any and I dont have the money to go buy some. Also where does it go? Does it go where the wire connects to the plug?
My dad said he has never used it and has never had any problems. Thats why im asking.

Dielectric grease acts as a moisture barrier in the plug wire boots (plug and coil pack), and also keeps the boots from sticking to the plugs when they are changed the next time. If you are going to keep the truck long enough to change the plugs again, dielectric grease is recommended.

Buddy - I wouldn't worry much about it.
The best way to protect your plug wire boots (and make them easy to get on and off) is to put a light coat of plain old vaseline on the plug before you slide the plug boot over it.
The whole idea is to provide a barrier against water intrusion (and thus: CORROSION) without insulating the plug from the wire. Petroleum jelly (vaseline) is good for that, and I always keep a tub of it around for batteries anyway. It only costs a buck and a half at the most.
*NOTE: Mark that tub of vaseline "GARAGE ONLY" with a black marker.

You do what you want. But I always use vaseline for that stuff, & I been doing electronic stuff for more than twenty years.

WD-40 evaporates and is not good for long term lubrication, temporary only.
Whatever grease you use, use sparingly. The grease will seal the inside of the boot, and if you have to take the boot back off for some reason, yoiu might have some difficulty. BTDTGTCCTSBC.

It was applied to the where the TFI module would contact the distributor and it worked as an electrical isolator.
Ever notice that brownish grease that was once used around light bulbs used for taillight and parking light sockets?

jdVaseline is a good enough insulator for the job your doing. i thing you'll need about 6,000 volts to jump across it.

That's interesting. In my experience, the grease actually helps keep the boot from sticking.
FWIW, the dielectric grease that Ford recommends for lubing/sealing the boots and other electrical connectors is also the same stuff Ford recommends for lubricating the slide pins on disc brakes.
