Hey guys, just bought some Nissan coolant non-premixed from the dealer of course and on the bottle it says "not for re-use". So I came to the conclusion that maybe I have to have it flushed before adding this in,correct? or is it o.k to just add on top? what is your take? Thanks for your response

 

How bad is your old coolant?

If you're just low, top up with the new stuff.

 

I would think that warning label is telling you not to reuse the bottle for other liquids like little Timmy’s apple juice etc.

 

 

lolll
