radiator stop leak
I have a small leak in my radiator and wonder if anybody has used bars stop leak. Does it work. What are the draw backs to worry about. 327/365 motor

Better to keep an eye on it and add coolant as necessary until you can get the radiator repaired or replaced.

Most people don't know how to use it correctly. They insist on dumping the whole container in the radiator. All that does it clog it up.
If you have a minor leak... where coolant is dripping very slowly... or just seeping... the stuff works miracles.
If you know how to use it.... and that means sparingly.
I'm talking about a small dash of the stuff... a bottle cap full. That's it.
It'll work.... check it out.
I've had it in my radiator 5 years.... stopped the leak in 15 minutes. Hasn't failed since.

Use it. A couple of years ago when I was freshening-up the engine in my 61, I thought I would give the radiator a good cleaning. I did and it had multiple leaks. It is the original aluminum radiator.
I used a bottle of the aluminum Bars. It plugged the multiple little leaks and have run it ever since. It will hold pressure over several days.

The original Bars is basically just wood fibers in suspension that plugs the small holes. The key is flush the excess Bars after the leak is plugged.

For small seep leaks.
Condensed milk.
I think that is what it is called, the real thick, gooey sweet stuff, or maybe it is evaporated milk, but I think it is condensed milk.
It will NOT clog anything, but as the stuff seeps out and the water and glycol evaporates, it leaves behind a solid but pliable plug.

Bar's is STILL installed in all new cars and trucks at the factory, to seal against tiny seepage leaks at hose connections; every vehicle gets two Bar's pellets at the radiator fill operation. My plant guys called them "rabbit turds".

Interesting, it's actually used in new cars!!!!! So is it a good idea to put a bit in when changing coolant components? Sounds like if it's good enough for the factory to have used for years it might be a good thing to do.

I Have Used Barr's Stop Leak In My 1995 C4 Coupe...
and it worked great. In fact, Richard Newton, who wrote a GREAT BOOK on C4 repairs recommends it in certain types of situations. I had a small but persistent leak of several drops of cooling system fluid that dropped on my garage floor after virtually every trip in my C4. I finally put in a really small amount - about 1 oz. in my system - and the leak stopped two years ago and has not returned. And as mentioned above, this product is used in new cars as well as being a factory authorized "fix" for cooling system leaks in certain models of Cadillac and Cherolet.

Just to be clear... this is a very bad idea if you were serious.
