Antifreeze recycling, does it work?

[JDMills]

I have had my truck almost a year and a half, and the first thing I did was to change the fluids, with the exception of the antifreeze. I had a local garage run it through a "recycling machine" that connects to a heater hose. The garage man said "your gonna love it" so I figured the system was set for a couple of years. today I drained the system to replace all the hoses, and I found a bit of tan sediment in the bottom of the drain pan.

My question is do Antifreeze recyclers work? or shoud I drain and refill?

The "anti-freeze" part of anti-freeze lasts forever, it is the corrosion inhibitors that wear out, unless the shop is adding more inhibitors to the recycled anti-freeze, they are just hurting all of their customers

Thanks for that information Eric, I will do some follow up at the garage and see where that leads to.
