Hey guys when installing frost plugs I was told to coat the edges with silicone and then punch them in. Does this sound correct and if so will any silicone do??

Thanks,
Keith

high temp RTV works best.
the orange stuff.

Personally I like the Permatex Aviation "Super 300" form a gasket.

Permatex® Super 300® Form-A-Gasket Sealant
Slow drying, non-hardening sealant designed to resist heat transfer fluids such as oil or antifreeze. Temperatures range from -65?F to 425?F (-54?C to 204?C). Resists antifreeze, aviation fuels, high-detergent oils and lubricants. Suggested applications: Use to seal precut gaskets or close machined parts.

Just my personal choice.

And it cleans up easily with alcohol.

Good stuff!

Never heard them called frost plugs before, always freeze plugs. I doubt a frost would do much damage to your engine, but a freeze sure would if you didn't have any .

This has been beat to death on here, but I couldn't resist. The CORE plugs are not intended to pop out if the coolant freezes. They are on the block as a means of removing the core sand from the casting process.
I have seen blocks split from deck to pan and the plugs were still in their original places.
