In the video, a person is seen working on a car engine. The person is using a blue hose to connect a pressure gauge to the engine. The gauge has a red, green, and blue needle that moves as the person adjusts the pressure. The engine appears to be a VORTEC engine, as indicated by the label on the engine cover. The person's hand is visible as they manipulate the hose and gauge, but their face is not shown. The video focuses solely on the action of connecting the gauge to the engine and adjusting the pressure.
