spark plug heat paste

[Callahanjc]

The question is how much of this heat sink paste should be put on the plug, A lot or A little,
Q.#2 is it ok to use heat sink paste from radio shack that has the silver in it, for better contact on block of motor.

Smear a little on all the treads, I don't know about the silver , But i use the Silicone base.

Is this something different from Anti-Seize that comes in silver and copper? Silver is recommended for all steel/aluminum applications. What I have on hand and use on other motors (havent changed the Can Am yet) is Perma-Tex 133A that you get at any auto store. Its used very lightly on the threads.

I had one bad experience with Anti Seize on Aluminum wheels a few years ago, :shocked: So i don't go near the stuff, No matter what the label says

It is different. Like Boborgera I have had corrosion problems with some brands of anti-seize on aluminum. Why take the chance? The recommended heat-sink compound is cheap...if you don't buy the monster tube from BRP.

BRP calls it heat sink but is it not just an anti seize that stops corrosion between the different metals aluminum & steel?

I think the stuff you have from Radio Shack is a thermal paste used between electronic components and an aluminum heat sinks and it probably isn't appropriate for engine compartments.

It has worked fine for me for several years. What conditions would occur in an engine compartment that would preclude its use? It meets the BRP general spec of a silicone-based heat sink paste. :dontknow:

It's not the same, anti seize does not transfer the heat away from the plugs like heat sink paste. Also note that even though the use of silicone base paste is a non conductor it only fills in the micro gaps but does not interfere with grounding of the plug.

this stuff is RadioShacks best thermal compound which has silver in it, But i think the standard thermal compound is probably better .

Heat sink paste

The Radio Shack heat sink paste with silver is electrically conductive which is good.
Here's my concerns with using it:

1. The interior of a computer or tv doesn't have hydrocarbon fumes blowing over it.
2. The point heat of a semiconductor is not nearly as hot as a cylinder head.

Sure, it might not cause harm, the silver is probably a bit better of an electrical conductor than the aluminum paste.
It falls, IMHO, under the same type of substitution as lard for ky jelly.

I decided not to use the stuff with silver, and went back to RadioShack and found the Heat Sink Compound that Nancytoy was talking about and wiped it around the threads like she said, plug project HISTORY:gaah:

I'm not too fond of mixing metals needlessly. There may or may not be a problem with it, but I don't wish to be the lab rat on this one. BRP recommends a silicone-based heat sink paste, and that's what I will use. Mixing aluminum, silver, and steel in the same joint just worries me. The electrolysis that sets up with alloy/steel joints when using some metallic based anti-seize compounds is an example of what can go horribly and expensively wrong. JMHO.

I don't understand,
Brp recommends the silicone based paste, Radio Shack sells a small tube that will last a lifetime for under 3 dollars, Why experiment with something else??

your right truth is they didn't have the silicone paste the day before at radioshack and i was wearied the stuff with silver could give me trouble on the next plug change . when i went back to the store the right stuff was hanging next to the other tubes so i bought a tube.
