Can't remember if I drained the distilled and put some coolant back in,
getting cold here.

Eke! That is not a thing you should have to wonder about - fix it! You will find a lot of opinions but I use Zerex G-05, it is close to the Volvo coolant formula.

will one of those bubble suction testers determine it?

Someone reviewed one of those testers recently on this site, to see how reliable it was. I think it was MrAl. I'm not sure what he came up with. What color is the stuff in there now?

You can definitely try the tester, but for not a whole lot more $ you can buy one gallon of coolant. Honestly I would just totally flush it out: run a few changes of water until the cooling system runs totally clear, then fill it up with fresh, 50/50 coolant. Then you can be certain about what is in there and when it was changed.

I changed it when we got the car a few years ago, then again when I did this belt.
It has had G-05 since I did the first flush.
If there was a reliable tester I would do it and then not worry but otherwise
you're right I should just replace it.
