Where are freeze plugs on a 225 slant six?

On a 225 Slant Six engine, freeze plugs, also known as core plugs, are typically located on the side of the engine block. There are usually two or three plugs positioned on each side, near the bottom of the block, and one or two on the rear of the engine. Their primary function is to allow for the drainage of casting sand and to provide a means for expanding coolant to escape if the engine freezes, preventing damage. Always consult a service manual for the exact locations specific to your engine variant.
