I have two things of BMW coolant in my garage but honestly can't remember if I had diluted them or not. If there a way to test this?

Specific density. Yet I don't know what the measurements are for each. The tool looks like a turkey baster with beads floating in it:

I have never actually thought about this but it's a great question. I would take a measurement of water and I will take a measurement of coolant which is not cut. That should give you a gravity range, I would surmise.

Water is 1.0sg. That's how SG is defined...by the specific weight of water for a specific volume :)
