Do levels freeze?

[SilverEscape]

We bought one of the big levels to put on the front of the trailer. Before we screw it on, we're wondering if the liquid inside is going to freeze over the winter? Wanting to make sure it won't bust or something.

And we get cold here. -40 cold.

Nope I think it's oil in there

or alcohol.

My husband has a shop full of levels and none have frozen at minus whatever ( I think our record is -43)

Nope, but in the hot sun, my bubble shrinks and disappears until it cools off.
