Nvm sorry I read your response wrong

Well I have a lot of left over coolant in my bottle, my resivour is full now it is common sense to reuse leftover's though is it safe? I don't want to have any corrosion or buildup, does the coolant expire inside the bottle or is this only special the coolant inside the pc?

Hey, I just made a custom loop and put in my coolant into my resviour. So I do know that I should flush and drain my coolant every 12 months though should I reuse the remaining coolant I have left in my bottle from what I used 12 months ago to refill my loop or just buy a new bottle?
