Product Name: Freeze Plugs
Product Description: Freeze plugs, sometimes called core plugs, are shown in the photo to the left. The plugs close the holes where the foundry core sand has been removed at the foundry. They also protect the engine block from cracking if the coolant freezes because of the lack of antifreeze. When the coolant freezes it expands. The expansion causes the freeze plugs to pop out, protecting the cylinder block from cracking. Several freeze plugs are located on the block as well as on the cylinder heads. During an engine overhaul, the old plugs are removed and new plugs are pressed in place. It is very important to make sure the plugs are pressed evenly into the core plug hole or leakage may occur. Follow the engine manufacturer concerning the use of sealants. Click on Core Plugs Leak Coolant for more information.
