This premix coolant (available at your GM dealer) is essentially a 50:50 mixture of GM Dexcool® (or other GM6277M compliant coolant) and filtered low-silicate, deionized water. The use of deionized water in hybrids, EREVs, and EVs is a necessity to ensure high-voltage isolation and to prevent the internal corrosion of cooling system components.
Wichtig ist gefiltertes, demineralisiertes Wasser (http://de.wikipedia.org/wiki/DI-Wasser) wegen der elektrischen Isolation. Mit Leitungswasser (elektrisch leitend) befüllt, sitzt man auf einer Bombe!
