water + redline vs Ice
Here's my comparison.
redline water wetter + water outperformed the stock antifreeze. I compared it with my daily commute to work. Idling at the light, the temp didn't hit past 215 F. (ambient is over 95 F). It cools down very quickly. 15 Degrees in less than two blocks.
I switched over to Engine Ice in the beginning of October. The weather is much cooler and less humid. Sitting at the same light with ambient at 80 F. the engine temp hits 220 F with fan kicking on. Temp cools 10 degrees in less than two blocks. There was still residual water + redline in the system so I'll flush that out next week with more Engine Ice (expensive stuff). I believe Ice is not a water based product. So far, I think redline is better. But I'll give Ice a few more weeks then I'll switch back to redline and compare results again.
note: redline + water does not have anti-freeze.
my next project in 2007 is converting to DOT5.
