In the video, a person wearing gloves is working on a car engine. The person is unscrewing the cap of a container and pouring its contents into the engine. The container appears to be a can of some sort, and the person is using a funnel to pour the liquid into the engine. The engine is open, and various parts of the car are visible in the background. The person's movements are deliberate and careful, suggesting that they are experienced in working on engines. The video does not provide any audio, so it is unclear what the person is saying or what the liquid is.
