Not sure how the concentration ended up so high. We bought this one at 119K miles and had not touched the coolant until after this report.

Well then its doubtful its the FF Then. Someone probably did a drain and fill and used concentrate. Possibly they just replaced a bad overflow tank and filled it with concentrate.

Dex-Cool in a neglected 2003 Chevrolet S-10 (50K) 8K ago. Great shape
Dex-Cool in a "randomly topped off" 2005 Saab 9-5 (58K) 25K ago. Great shape
Dex-Cool in an "in service" 2002 Saab 9-3 (113K) 1K ago. Great shape
Dex-Cool in a "randomly topped off" 2002 Saab 9-5 (125K) 40K ago. Great shape

Cleanse as necessary. Rinse with distilled water. Use distilled water to dilute to spec (50%).
Dex-Cool is A-OK in my book. Kira

I'd never put any of that stuff in anything I own, but in the trucks I maintain, it has performed flawlessly. Always replace the Dex with Dex when something goes down. I installed coolant filters on all of them, just for the extra safety measure.

During the service life of the coolant the water is boiled out. Every year I have to add 1-2qt's of water to my vehicles due to the water being 'cooked" out from the summer time heat. Example, I changed the coolant in my durmax. When I refiled and bleed the system out the ratio was 50/50. About 1 1/2 years later (30k miles) I was 2qts low on coolant. When I checked the ratio it was off a bit..over %60 dexcool. I added the water and that brought the ratio back down to what I had it set to.

Even some owners manuals say adding water up to 4 times a year is acceptable.
