What coolant are you talking about? I use the blue Pentosin and mixing is a must unless you are in -25. Michael.

Water is a solvent. It will dissolve anything water soluble. Neither steel nor aluminum is water soluble. This notion that distilled water will corrode your system is a nonsense. In fact, impurities in the water could well act as oxidizing agents, causing the steel to rust, and the aluminum to become aliminum oxide.

But in the first place ... the coolant from VW comes already diluted. Why is anyone mixing anything into it, distilled or otherwise?
