    Good, informative video. The vacuum fill tool, while a specialized tool, is actually not that expensive and is nice to have if you are an "intermediate" or higher level DIY mechanic. It is made by Schwaben and ECS Tuning sells it for ~$80. I have it and it works great. I have not used it on my F80 yet for either cooling system, but I have used it on my son's 128i with N52 engine twice. Makes the fill process seamless, with only one bleed cycle required to burp any residual air in the system.

    Extremely interesting video. This answers a lot of questions I had. A question: do you know how the S55 cooling system relieves itself of pressure in case the expansion tanks are not enough? I don't see a pressure relief valve in the circuit, nor observing the radiator of the car in your coolant change video. I'm intrigued.

Have not seen the stain/seepage since, should I order a new cap? What coolant do I use to top it off. Thanks for the video, it calmed my nerves brother 🙃
