Heatsink grease. You can use grease meant for mounting PC chips if you want.

Re: Is the ICM supposed to Heat Up?

alright for some reason im having trouble grasping this concept (sorry)

could you tell me on this pic where exactly your talking about? http://shbox.com/1/ICM_air_gap.jpg is the heatseak the bolts going into the head from the ICM and do i put the grease on that?

also im guessing this is a good price for heatsink grease?

the ICM is just the black plastic piece to the left of that silver(aluminum)piece, which is the heat sink, and the grease goes between the ICM and the heatsink

Re: Is the ICM supposed to Heat Up?

ah I see...

ive never gone into the ignition stuff of this car, or any for that matter, so i never realized that these were two different parts. So when i take off the ICM to do the washer work the heat sink will not be attached to it and i can just rub the grease on it then they will bond together and then just put it back on like shoebox's instructions?

i guess the easiest way to put it for me would be.. insert grease where...

Re: Is the ICM supposed to Heat Up?

Take the ICM off.. [black part in lower right of the pic] if I recall correctly the heatsink [the finned aluminum part, lower right of pic, right under the ICM] is pinched [by the 2 small bolts] between the ICM, and the steel bracket [the third, or bottom piece, of the lower right of pic] that forms one half of the coil bracket [the other half is the lower left steel bracket in the pic]
Now clean all that cheap*ss silicone grease off, and use CPU heat sink compound [Arctic silver?etc?]
Start by applying on the rear of the ICM to the aluminum heatsink area..
Then apply the compound where the heatsink contacts the steel bracket..
Then apply to where the 2 steel brackets touch each other..

IF you were putting it BACK on the cylinder head then you would also apply thermal compound to where that last bracket contacts the head..

IF using the 'washer/spacer mod', then DON'T apply the compound to the rear of the bracket..

[I added a piece of aluminum plate, to assist the dissapation of heat, so I put compound between the steel bracket, heat sink, and my aluminum plate.. this is optional tho]
Remember LESS is best when applying the compound.. you're just filling the voids in the metals, it doesn't need a lot..

Re: Is the ICM supposed to Heat Up?

I used some dielectric grease when I wiped all that grease away to clean off the heat sink. Would this work just as well or should I be getting worried?

Re: Is the ICM supposed to Heat Up?

Dielectric grease is not the same as heatsink compound and will not transfer heat nearly as well as the right stuff.

Re: Is the ICM supposed to Heat Up?

Can anyone tell me what this is? I was taking off the first nut on the left side of the ICM (facing the car not drom drivers perspective) and this was on the stud with everything else. It wasnt mentioned in Shoebox's directions or by anyone else and I was wondering if anyone knew what it was/where to put it.
