The video shows a close-up of a person's hand holding a bottle of radiator fluid. The person is pouring the fluid into a radiator. The radiator is black and appears to be part of a car's engine. The fluid is a reddish-brown color and is being poured carefully into the radiator. The person's hand is steady, and they seem to be experienced in this task. The background is blurred, but it appears to be a garage or workshop setting.
