On a 1999 Ford Ranger XLT with a 4-cylinder engine, the freeze plugs (also known as core plugs) are located on the engine block. Typically, you can find them on the sides and rear of the engine block, as well as on the front of the cylinder head. Their main purpose is to prevent the engine block from cracking due to freezing coolant. Accessing them may require removing certain components, depending on their location.
