    Default dielectric grease ok for ignition control module ?

    guys, i installed a new ignition control module on my 1990 k1500 5.7 today. i did not have any of the white grease that usually goes on the bottom, so i used some permatex dielectric grease, the clear kind.
    will i be ok, or should i get some of the white stuff ?
    thanks

    I want to say Autozone sells it in little packets, commonly used on trailer plugs, but dont quote me on that.

    That would be dielectric grease. You can get heat sink compound ar radio shack... Probably at the auto parts store too. Never looked for it there.

    Moogvo's spot on. You want heat sink compound. It's a grease/paste that has little bits of aluminum or silver embedded in the compound to enhance thermal conductivity. You can find it at RadioShack or Best Buy in the computer aisle. It's commonly used on heatsinks for computer processors.

    It's crucial the ignition module has good thermal conductivity to the housing it's mounted to. The module produces a lot of heat and is heat-sensitive. Run it without it for too long and you'll be replacing the module again.

    glad to hear this... the guy at work is not a car guy, and i tried to explain what i was doing, and the little tube said "thermal" something, but wasnt worded "heat sink" paste, so im just making sure..
    thanks for the input... i now feel safe...
    autozone did not carry the white stuff, i tried talking them to give me some out of a new ignition module box, but obviously they didnt want to do that.
