Quick question. My plug wires came with a tiny packet of silicone grease. It says apply it thinly to the interior of the boot and to all sides of the distributor rotor tip. So not necessary on the metal correct?
It doesn't say to apply it to the metal connectors or anything but I thought that's what some people do also.
 
I have never heard of putting it on the rotor tip and I don't think I ever would.

Take a screwdriver, put a little bit on the end of it, then take it and swipe it on the inside of the boot that goes over the spark plug. (to ease the instalation and REMOVAL of the boot on the spark plug) Put a touch of it in the outside of the wire also where the plug boot slides in it (again to help the spark plug boot slide on the actual plug wire and again to aid it in removal at a future time. Do the same to the dist. cap ends.
 
It's dielectric grease. apply it to the surfaces as requested as well as the metal ones. It helps prevent corrosion. I've been doing it for years, it also helps with removal at a later date. Just don't go crazy with over lubing it. It works great for all electrical connections that are metal to metal.
 
Yep,I use it on my plug wire boots all the time.Even on light bulb sockets so they wont corrode and rust out.Ever had to remove a corroded ,rusted on tailight bulb?It really sucks.

Yeah same, I've only heard of putting grease on the rotating metal cam when you put new points in. It just says it's recommended for the rotor tip also to reduce RFI emissions.
 
Yeah I've used dielectric grease on landscape lighting bulbs before. Thanks for all the tips.
 
One caveat----not all "dielectric grease" is silicone based. I used to service HVAC, and although I'm not an electrician, certainly was "into" some of this stuff. The greas you get---for example---commonly used in electrics for things like aluminum wire connections is NOT commonly silicone. I would be a little concerned that "some other" material would damage silicone wire insulation.

First time I saw grease used in auto applications was the "Trucklite" sealed tail lamp assembies, and of course now all the manufacturers use it in their connectors.

Well I was wondering on that. It doesn't say dielectric on mine anywhere so was wondering if this one would go on the metal parts. Just says silicone grease. Just says it helps take them on and off and they barely gave any grease. So doesn't seem like enough for the metal parts.
 
Auto parts store will sell you some dielectric grease. I always put it inside the spark plugs boots. Like others said it keeps corrosion out and allows the plug wires to come easily at a later time.
