What happens when a freeze plug pops out?
If the water in your engine block freezes, it will expand and push against the freeze plug. When it does, the plug will pop since it is the weakest element of the engine block. After that happens, the coolant/water will leak and trickle down the engine, further damaging the engine block.
Why would a freeze plug come out?
Freeze plugs are small, cylindrical-shaped plugs that are used to fill the passages in an engine created by the sand cores. 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.
What causes a freeze plug to go bad?
In some cases, as the water freezes and expands in your block, the freeze plugs will push out relieving the pressure of the freezing water and partially draining your cooling system. However, freeze plugs can also start to leak over time simply due to the heating and cooling cycles of driving your car.

Do Rubber freeze plugs work?
After some research and asking around, it seems that pretty much only southern mechanics have ever heard of rubber freeze plugs. They are pretty much not used in the north because of the extreme cold temperatures that render them pretty useless.
Are brass freeze plugs better?
The only advantage steel freeze plugs have over brass is slightly better holding power as steel is not as soft as brass (tension holds them in place better), which is one of the reasons why the factory used them (as well as cheaper cost). Brass will not rust out.
