Re: [Chrysler300] Freeze plug for F

I used JB Weld for the very simple reason that George Riehl taught me that it can fix many many things.

As has been pointed out by several others. These holes are actually core holes, used in the casting process of the block and heads.

I do not understan the use of JBWeld in freeze plugs (seems to me if they ever needed to be replaced due to corrosion it would be very difficult.).Also would that would inhibit the intended purpose and prevent them from popping out if the water did freeze.(not that that really happens if maintained properly.) So in effect these are actually casting hole plugs and we are not concerned with freezing. Personally I have only seen these pop from a freeze, in a boat engine (which usually do not have antifreeze solution in the water jacket) and then only after the block was cracked.......

Would something like a head gasket adhesive be OK?

I repeat that the original style plugs are excellent if properly installed.  I personally use the brass versions so that corrosion is less likely an issue.  I keep things a long, long time.  Other types of plugs might be a bit more forgiving of installation and maintenance errors and carrying an expandable rubber plug as a spare is not a bad idea.   Another thing to remember is that our old cars were not designed to have pressure caps installed to create the pressure at which our modern cars are typically operating.  If you use an excessively high pressure cap you are at greater risk.
