Why do engines have freeze plugs? Freeze plugs were originally used to protect engines from cold-related damage. If the coolant inside an engine freezes, it may cause the block to crack. … Freeze plugs prevent this from happening by allowing the frozen water to expand out the plugs’ passages. After a freeze plug has failed, however, it must be replaced.
What is the purpose of freeze plugs? Core plugs, also called freeze plugs or Welch plugs, are used to fill the sand casting core holes found on water-cooled internal combustion engines.
