Engine Works Freeze Plugs

Engine Works freeze plugs are small, circular metal discs pressed into an engine block or cylinder head to seal holes created during the manufacturing casting process. They prevent coolant from leaking and are designed to pop out if the engine coolant freezes and expands, theoretically saving the engine block from cracking.

Additional details:

* They plug holes used for removing sand from the engine block casting
* Brass material is used for superior corrosion resistance
* Failure signs: A bad freeze plug often leads to a strong coolant smell, white exhaust smoke, and engine overheating
* Sometimes referred to as expansion plugs, core plugs, or Welch plugs
* These components are crucial for maintaining the integrity of the cooling system and preventing catastrophic engine damage
