Hey Guys i was just reading about coolant types and found something really confusing and need clarification.
Green IAT coolant (the one available here as Osaka and Guard) contains silicates. Silicates are used as corrosion inhibitors but some manufacturers argue that silicates erode aluminium and hence is not safe for aluminium block engines while other say silicate protect aluminium however they are not long lasting (30 to 40k Km). If silicates are harmful then one should stop using green IAT coolants? (some reputatible brands like AC Delco and Prestone also manufacture green coolant)
