Bars stop leak

[Car Nut]

The heater is fine nothing plugs up they wouldn't make a product after all these years that would plug up a free flowing heater core. The product is designed to stop a leak under pressure with a very hot metal surface 200 plus degrees, at the same time, such as a leaking gasket or crack.

Plugged mine...

They used to make a radiator stop leak called Egg White. My dad told me the name came from back in the old Model T days when they would put actual egg whites in a radiator to stop a leak. The egg white would cook into a thin coating on the inside of the radiator. You have to remember that the new products are more refined derivative of the same concept and are a hopeful temporary fix as opposed to addressing the real issue. They used to temporarily fix a lot of stuff with duct tape and bailing wire too, but that is not the preferred method.

This works in a pinch. Better just to repair the leak
BTW if you're out of town and your radiator runs dry. Do not resort to filling it with beer.
The beer will only froth up, give no cooling assistance and stink for a looooooong time afterwards.

...or drinking the beer then filing it.

Sounds like a GREAT idea at first.....

The bi-product of drinking the beer smells worse than the beer being used in the first place.
