coolant question

[jw1]

I am going to try and do a coolant flush in the next month or two but for now my overflow tank is running low by almost 1/2 gallon. Can i add just distilled water for now to top it off since it's starting to get warmer out or should i add a 50/50 mixture of zerex g-05 coolant?

What was in it before? If you used premix only premix "should" be added but if you mixed it yourself add distilled water. In a pinch you can add just distilled to get you by.

Yes for now you can just top it off.

It's still the factory fill which i believe is the g-05 hoat coolant. I have 92k on the clock and heard it would be a good idea to do a flush and change the t-stat around this time. BTW it's an '07 forgot to mention that earlier.
