I remember years ago I had to use an egg white in an emergency. It worked, and never leaked again.

Best to fix the leak properly before they goop circulates all over the never regions of your cooling system.

Heat for the price have used it once on a scrapper .. worked well. (edited)

Not ideal for modern cars, too many voids and sensors can be blocked by it. Fix it properly IMHO.
