Where is the drain screw for the BMW 5 Series radiator located?

The drain screw for the BMW 5 Series radiator is located at the bottom of the radiator. Opening the screw will allow the water to drain. Introduction to the car radiator: The radiator is the main component of the car's cooling system, also known as the overflow tank. Its function is to maintain the engine temperature. How the radiator works: Through the circulation of coolant in the engine water passages, it absorbs heat from the cylinder block and then dissipates it through large-area cooling fins to maintain the engine's optimal operating temperature. The radiator is composed of hollow copper tubes, where the high-temperature coolant enters the radiator, dissipates heat, and then circulates back to the engine cylinder walls. Main functions of the radiator: When the engine's water temperature is high, the water pump circulates water repeatedly to lower the engine's temperature, thereby protecting the engine. In winter, if the water temperature is too low, the water circulation will stop to prevent the engine from becoming too cold.
