I used a Gumout flush chemical I had sitting around. I followed the instructions. I added the flush and let it run 10 minutes after reaching normal temperature with the heater on. It has yet to overheat sitting at Park in idle anymore but I drained the radiator out but instead of adding distilled water and running it another 10 minutes I actually took the radiator out. It looks really bad on the radiator fins. I've looked around online to see about possible cleaning solutions to let soak in it but nothing was trusted. I saw people use vinegar, baking soda, coke, and even CLR. I was thinking of CLR but figured it would be too caustic, which turns out to be true according to their website someone posted about. I took the radiator out and flushed it out good with the garden hose but it's got to be full and soak to break up some of the deposits. Is vinegar the best bet? It looks like if you lay it flat up and fill it up it will be able to soak. I'm sure it will cost just as much taking it to the radiator shop as buying a new aftermarket radiator. So if there is a way to clean it at home I would like to try it because it's a good radiator.
