I see Dex-Cool is recommended for his car, as is Peak Pink.
Please give me your opinions.

I would top it up with distilled water and keep an eye on the level. If it stays up then the couple of cups of distilled water will have a negligible impact on the mix ratio- if it drops then you need to figure out why. But, since the coolant is yellow it is likely original- a flush and fill might be prudent.
