Alan I drain the mixture usually leaving it in no more than a couple of days. Never experienced any plugging of the radiator the mixture only plugs when it gets into a leaking area. Actually amazing how it finds the leak and plugs it. Heres an example. One time I had one of my race engines with cracks on the run stand. We use smaller hoses on the race engines lots smaller than the hose size used on the run stand. To solve the hose size issue I quickly put together a bunch of fittings that I knew would leak but figured it would be good enough for the short run time needed to circulate the water and sodium silicate mixture. As I expected the quickly thrown together fittings definitely had leaks however like magic once the circulating water was around 140 degrees the leaks stopped the sodium silicate sealed everything perfectly. But theres is one draw back to the leaking water mixture it will leave stains on painted surfaces but quickly cleaning up the spills will eliminate the staining.
