these two perform opposite functions, correct?

HTC needs to be used between ICM and heatsink and dielectric between heatsink and motor, correct?

HTG promotes heat transfter, Dielectric grease promotes conductivity... that sounds right to me

Janny

In place of HTG, you can use ordinary silver "Never Seize" compound. Somebody here tested the stuff, and discovered that it is as good if not better at conducting heat. I use it now too.

Thanks guys.

I'm put my new ICM on last night and I cleaned off whatever kind of greese is between the heatsink and the engine. Is it terribly cruicial that I have dielectric greese there?

You need the HTG for proper cooling of the ICM. Use the same between the head and bracket or space the bracket away from the head.

Dielectric grease does not promote conductivity. It does just the opposite.

Actually, what I was talking about was between the heatsink and the bracket. My thoughts were that we want to keep the heat from the head away from the ICM and the heatsink, so we need to use some kind of an insulator between the heatsink and the bracket, right? I'm just talking out my butt here. Shoebox?

Also, my ICM just came with a tiny bit of HTG. The auto parts stores don't carry it separetly, anybody know where I can get more of that stuff?

I think I'll just take Shoebox' advice and space the whole bracket away from the head.

Also, I picked up a Wells Lifetime warranty ICM, anybody have any good/back experiences with those?

Any part of the "sandwich" should have the HTG. The factory location actually uses the head for part of the heat sink, but at least one person has thermally tested and shown that the ICM will run cooler spaced away. However, after the engine is off, the head cooled down faster than the ICM. I don't know how long of time elapsed until their temperatures equalized.

are you sure? Thanks for catching that....
