Freeze plugs are small, cylindrical-shaped plugs that are used to fill the passages in an engine created by the sand cores. During production, passages are created in engines that allows for the removal of casting sand. To fill these passages -- and therefore protect against coolant leaks -- automakers use freeze plugs.
In the past, plain water was used to cool combustion engines. While effecting at removing heat, plain water is susceptible to freezing. When the water coolant inside a vehicle's engine froze, its freeze plugs would push out. Automobiles today no longer use plain water as coolant. They use a combination of water and antifreeze. Nonetheless, you should still use caution to protect your engine's freeze plugs from failure.
You could drive with a freeze plug leak if you are left with no choice. In theory, if you can maintain the engine coolant level of your car and ensure that the car's engine doesn't get too hot, you might be able to drive with a freeze plug leak, though you shouldn't do so.
