If the coolant inside an engine freezes and the water expands, it will create pressure that causes the engine blocks to crack. Plugs used to prevent this by allowing the frozen water to expand out the plugs' passages. The engine expansion plug is also known as freeze plugs or frost plugs, a permanent method for sealing manufactured holes in castings or other processes. These plugs prevent coolant from leaking. It is necessary 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 and might cause extensive damage to the engine. Replace it with a proven and tested product like Plug from Volvo Penta. They are good to use in limited space depth holes but require a counterbored hole to locate it properly.
