ignition module grease - ZR-1 Net Registry Forums

Blownrunner · 01-12-2013

Met an interesting guy whom owns an 88' prototype among other things, filled me in on a lot of the little quirks of the zr-1. Apparently, the grease used on the ignition module on the underside of the plenum is there to cool the module. Anyone know what type of white grease this is? Can I just get it at an autoparts store? Thanks.

Radio Shack "white heat-sink compound" - just one! 276-1372

Caution:

The layer of heat sink grease should be thin - So thin if fact that you can make out the color of the aluminum of the heat sink.
Also! (related to me by Mark Haibeck too), be very carefull to keep dirt - espcially sand (or the like) from sticking to the surface and get sandwiched during re-assembly. It is very likely to result in the DIS module over-heating (obviously being held off the plenum heat sink by the grains of sand).

Just a thought...

PW - "thin" = "just one" !! (6.5g and you should have excess I believe)

Was nice talking to you last night. I take it you got home OK, is it still idleing at 3K?

Thermal grease does not have to be white.
It also comes in clear.
White is easier to see when applying.
I use a military grade thermal grease which is clear.
I've had this tube for almost 40yrs.

Here is one inexpensive single use non military source:

No air bubbles either.

I saw a pc shop tech put the paste on the back of the heat sink, IN A LITTLE RING

I've read twice that copper anti-seize has better heat conductivity that some heat sink pastes, and I don't know how to test for heat conduction...

I use Dow Corning 340. I took it apart after 3 years of use and it was still as greasy as when applied, no drying, or cracking. It's white.
