Use distilled water only! Don't use tap water. It WILL corrode. I mix distilled water and water-wetter at the recommended ratio. WW is a surfactant as previously stated. I have seen some folks use liquid dish soap too...breaking the surface tension allows the water to have a larger contact area along the wall of the water passages in the engine. If the water does not follow all of micro-contours small steam pockets will develop. Steam does not transfer heat nearly as well as water.gkotlin;119936 wrote: I...Straight water isn't good for corrosion resistance. Thus adding the water wetter to help restore the corrosion resistance.
The last time I had my '04 VFR on the track I saw temps as high as 250. It didn't miss a beat. I was using 50/50 coolant/water mix.
