Radiator Drain Plug
A radiator drain plug is a small, typically metal component located on the bottom portion of a vehicle's radiator. It is designed to allow for the easy draining of coolant from the radiator for maintenance purposes, such as flushing the system or replacing old coolant. The drain plug is typically threaded and can be removed or tightened using a compatible tool, such as a wrench or socket. Proper care should be taken when removing the drain plug to avoid stripping the threads or causing damage to the radiator.
