Just checked coolant after thermostate replacement

[MosH]

2 issues:

1, the coolant indicator is just below the kneck of the fill hole, based on the picture I see it looks like it should be above? I guess I am low and they did not top it off properly

2, when I first started the truck today I took the cap off and I can see water squirting out of the small hole just below the fill kneck, it was clear and had no smell, did I get a nice fill of water just before a NY winter? The guy claimed to use BMW coolant and even stated it on my work receipt.

Any input on clear almost smell free coolant?
