Default Quick question...Where does the grease go? ..Edited...

I am about to replace plugs and wires. Wires came with the dielectric <(speling) grease....SILLY question, does the grease go on the threads, or on the capped end of the plugs??

Squeeze a little on the inside of each spark plug wire boot of the new wires on each end of the wire. If you don't have enough, just use it on the spark plug end of the wires.

not a bad idea to put a lil anti-seize on the threads

Buy more grease if you don't have enough to do the coil posts. Coil posts are notorious for corroding.

Anti-sieze isn't even remotely necessary on a spark plug, and frankly, I'd be hesitant to put anything non-conductive in that location.

Are you referring to just the 3800 series, or all cars in general? I put anti-seize on my spark plugs because I have aluminum heads, and even with doing that they still get pretty darn tight.

all cars in general, yes. usually, pugs wont (still can) get stuck in cast iron


but always use it if you have aluminum heads.

If your plugs stick in a cast iron head, you're over-tightening them or leaving them in too long.

Do it if you want to, but there'* absolutely no reason to whatsoever on a 3800. If there'* 5 people out of 5000 here that use anti-sieze, I'll be surprised.

Count me as #1. I always just thought it was the correct way to do it. Then again, I put miles on slowly, so time wise, my plugs do tend to stay where they are for a while.

But yeah, back on topic: It doesn't take a ton of that grease, in my experience. Just coat things up nice, and you're good to go.

Well gentlemen, the job is complete. It took me 3 hours which is 30 minutes per plug....
It all went well, I took my time.
My body is old and it doesn't like being in weird positions for too long.
I was surprised that the wires came off as easily as they did.
From what I heard here, it should have been tougher.
The part that took me the longest, was fitting the new wires in the harness, routing them correctly, the way the old ones were.

--EDIT--

I replaced these AC Delco with NKG copper V power:

The three on the left came from the back...Rusty plugs?

Look at these tips. Did they really make them pointed like this, or have they been worn away this way?


This sleeve was on the back 3 plug wires. What is the purpose of these? I put them on the new wires.


Also, I had a rusty contact on an ignition coil. 5 of them were bright and shiny, but one was rusted, I cleaned it up with steel wool and greased it.

After all of this, it started up better than ever......thank you all for the advice
