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.Also known as core plugs, freeze plugs play an important role in protecting automotive engines from cold-related damage. 

Water expands as it freezes, and the pressure created by this expansion can cause cracks to form. 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. 

Freeze plugs, also known as core or frost plugs, prevent coolant from leaking from your car. Freeze plugs are very important when it comes to the maintenance of a car, especially in warmer climates. Without coolant, your car's engine can reach unstable conditions, causing a breakdown.

Freeze plugs are located on the front, back, and sides of the engine. The front and side freeze plugs are accessible, but the rear freeze plugs are not. The transmission needs to be removed if you're unlucky enough to have one of those leaking.

Freeze plugs are an essential part of your engine, because they keep coolant from leaking out. If you neglect a leaking freeze plug for too long, your engine's coolant could potentially leak to a level where it can no longer effectively cool your engine, and cause it to overheat, risking extensive damage
