Distilled is OK.
I do NOT recommend deionized water.
This goes into buffering also.
Since the definition of deionized water is pure H20 with nothing else in it, this causes a negative potential.
Because of no buffer, any ions / minerals / etc. that it comes into contact with will cause it to leach into it.
Deionized water can literally suck ions out of the atmosphere.
This can create potential problems.

Anyone who takes care of aquariums should be aware of this too.

actually chemically its as neutral as it gets since it has no ions in it. The coolant you is the buffering agent. Ions dissolve based on solubility and saturation of the compound being dissolved. The pH just reflects how much H3O+ there is in solution and having no idea whats in the other water sources, there can be ions causing it to be too basic or too acidic so its best to have a happy medium. Hence why we used deionized water for everything in the lab including the cells I made in school. Ions arent all created equal.

Biologically speaking deionized water lacks any nutrients which is a whole other issue.
