Where is the freeze plug on hiace van?

In a Toyota Hiace van, freeze plugs (also known as core plugs) are typically located on the engine block. They are installed to help protect the engine from damage due to freezing coolant. Depending on the engine model, you may find them on the sides or rear of the engine block, often requiring the removal of certain components for access. Always consult the vehicle's service manual for specific locations and procedures.
