Blue liquid inside the PW box

[Dan123]

So I am having the Powerwalls installed today. One of them, when they opened the box, had some blue liquid inside the box. Not a lot, but significant to be noticeable. The installers say that it is not a big deal, it probably splashed from being upside down, and it will work even without the coolant.

Has anyone seen this blue liquid? Is there some place to top it off with anti-freeze?

The standard coolant used in Tesla vehicles is G-48 automotive coolant which has a blue color. I assume they use the same in the Powerwalls and Powerpacks.

No need to worry. Powerwalls have a pressure relief valve. Sometimes the Gigafactory overfills the coolant system which can cause some coolant to release during shipping. The system is designed to never need a refill. Therefore, refill is not possible.
