well i decided to flush the whole thing after i found that a leaky hose was causing my water leak(much relief). i tried some stuff from PRO-Blend that you can pick up at autozone called "stops overheating". im curious as to who else may have tried this. im noticing that i get a higher temp than normal so i may be going back to 80/20 with water wetter distilled H2O. i have a koyo and with out fans my temps before and after the flush would reach 215-220 degrees. sometiems a tad higher if its hot out. i just cant seem to get a good temp reading without fans on. im looking to get no higher than 210 without fans, but dont seem to have found the right ratios. anyone else having high temps even with a koyo or fluidyne etc...
