They forgot to mention that it also plugs heater cores and radiators.

Actually it is waterglass. A chemical originally used to stop leaking hot water boilers. Available cheap from a pharmacy. Technically it hardens much like glass in the area of combustion. I have noticed it also puts a glasslike insulating coating on a large portion of the water passages.

A favorite of used car dealers to cover up cracked heads and blocks years ago. Sometimes it even lasted. Not advisable to use in my opinion. Not because it will not serve it's purpose. It is the coating everywhere that distubs me. Waterglass is well named. When hardened it looks like glass and you put it in water. The first time you remove a head that had this done you will see what I mean. You cannot miss it.

Sodium silicate is water soluble, how would it build up in passages? I can see it maybe fixing the HG since it may form a silica type substance when you burn it. Its very resistant to heat. I use it as a glue for homemade model rocket engines.


But yea it doesn't sound like a good idea. I wouldn't want to add any inorganic chemicals to a coolant system. Id imagine a displacement reaction could occur with the Al in the cooling system

I have used the silver stuff that comes in the cylinder many times as a temporary solution. I have not had any negative effects from it that I know of. The main cause of the leak is bound to get worse eventually and require repair though in my experience. I have also used it when I cannot find the source of the leak.

I wonder if that crap was the cause of this:

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

I cannot answer why the stuff coats passages like I have seen. For starters I always thought it required exposure to very high direct heat to set. All I know is it was quite visable in the head water passages. I figured it had to be waterglass as was just like a coating of glass.

I have no ideal who installed that stuff in the engines I saw it in. The quantity used must have been substantial though.

Isn't this the same goop that was poured into all the engines on cars turned into the cash for clunkers deal, sodium silicate?
