Can I get a good answer, Thermostat question?

Spareparts, thanks for the video but he is not doing it right, did you notice that? He is putting in the rubber seals then holding the thermostat up against it, the thermostat fits into a groove on the seal and he is not doing that but I think the top of the seal faces the short part of the thermostat , check out the video h he is doing it wrong. But thanks for posting it
