Blue coolant?
 

The 2007 V50 needs a bit of coolant and to me it looks blue. What's up with blue coolant.

I do have some around for the S60, it is G-05. Can I use that in the V50?

Early spring I was too lazy to replace the top motor mount and took it to a shop. I am thinking that they may have lost some out of the reservoir when they moved it out of the way.

I'm also thinking they spilled some on the serpentine belt and pulleys. From the day I picked it up from them the pulley or belt has been making a noise.
