  • Q:

      Freeze plugs are a protection device on the motor. When water freezes, it expands. If water freezes inside your engine block, it can expand and crack the block, destroying the motor. Freeze plugs (or expansion plugs) will "pop out" and hopefully prevent this. The part that keeps the coolant and oil from mixing is the head gasket.
