Absolutely use dielectric, just a thin film. It's for dissipating heat. Can guarantee it will fail without it. Clean the surfaces first.

I thought "thermal paste" is the right stuff, not dielectric grease?

NO, NO, NO!!!
Like @gmbellew said; you need a thermal paste, sometimes referred to as 'heat sink grease'.
Get a genuine GM module. DO NOT get any generic modules from auto parts stores. You have been warned!

Anything getting hot expecting heat transfer to another material uses thermal paste. you can get a small can of it cheap on amazon....and that small can will last you a life time.
the processor on your phone or computer uses it to transfer heat away from it.
Where it's needed...a little goes a long way. Read up on it

when you buy a new module, at least an AC Delco one, it comes with a little bit of thermal paste, not dielectric grease. I'd say the Hanes manual has an error. Thermal paste is what you should use.

I've worked on and installed everything with electronic ignition that Bosch makes, and its ALWAYS the white thermal paste....and yes, things fail when its missing. Thats all I would use.

I've always used "dielectric grease" it's never failed and I got it when I worked for the USCG. They used it on their Jayhawk helicopters, good enough for me.

Don't over think it. Either one will work. Always had dielectric in the tool box for other uses. Have used it for 30 years, it works. So may thermal paste, didn't have a reason to stock it.
A GM module would be preferred.

No, this product protects something from heat. It is the opposite of what is needed. You need a product that easily allows heat to move through it. I use the stuff used in the computer world. Mine is Arctic Silver, high density polysynthetic silver thermal compound. The module generates heat. The heat must transfer from the module to the distributor to make sure the electronics don't burn out within the module. Those are not real fun to change so do it right the first time. That way you are not out in the middle of nowhere broke down.
