Where is the coolant reservoir on a Toyota hiace?

The coolant reservoir on a Toyota Hiace is located in the engine bay, on the passenger side of the vehicle, near the radiator. It is a white or translucent plastic tank with a black cap, and is usually marked with the words "Coolant" or "Radiator." The coolant reservoir serves as a storage area for excess coolant, and helps to regulate the temperature of the engine by allowing the coolant to expand and contract as needed.
