I flushed the antifreeze from my Chevy Cruze 2014 and loaded Dex-cool, I am not sure whether it is concentrated or not. Should I worry about it ?

Thanks.

Since it has already been loaded in the car, would you advice flushing it again or adding distilled water ? it might be hard making it 50/50 without flushing.
How many gallons did you add and was it all straight? If so, you could drain half of what you added and put half distilled back in.

Sure, will do.
It was almost a gallon ( all straight), what would you say are the consequences of having a full concentrated antifreeze?
It just won't cool as well as having it mixed.

Buy a simple coolant tester to see what your freeze protection is.


This will tell you what your mix is if is 50/50 or 75/25 or something different. If all 5 balls float then you have all coolant and almost no water which is not good. You need a mix of water and coolant for best heat transfer.

if you have 3 balls floating then you have about a 50/50 mix. 50/50 is the ideal mix, if you don’t have this then I would extract 1 quart of coolant and then add 1 quart of straight water. let it mix well for a day or so and retest. Keep repeating until you get the mix down closer to 50/50.

Should have added, based on packaging images I can find on the web, the jug you bought is probably the concentrate and not a 50/50 mix. Seems that if it is a 50/50 mix it will explicitly say on the packaging that it is 50/50 mix. Now when you add water it’s best to get a gallon of distilled water from the grocery store so you are adding pure water with no tap water additives. I will be honest and say I don’t completely know the total reasoning other than that is what I have read from pretty much every source I have found about coolant.
