freeze plugs are on the block to prevent any water from expanding and cracking the block. instead of costing you a motor block you just replace a freeze plug all they are is a sacrificial safety precaution. to replace them you need to remove the old one by dropping the oil pan and praying it made its way past the crank then using a brass hammer tap a new one into the open hole in your block
