[QUOTE="Izso, post: 1063750814, member: 2429"] Ok Drex, this is one time I get to hammer you for doing something bad. LOL - Coolant has a higher viscosity than water meaning it will not flow as well as water....bad #1 - Coolant by itself is not a good conductor of heat compared to water. Meaning it won't carry heat as well as water... bad #2 so by this conclusion, you get slower flow rate, lesser heat dissipation and overall poorer cooling. But there's more - Too much coolant may spoil the water pump in the long run if the mixture is too thick (high viscosity)... bad #3 - The mixture may turn corrosive. But this only Drex can confirm since he's the chemist major. But a general search on Google will say it may result in higher corrosion either because of the coolant itself or because it wasn't enough to prohibit corrosion (coolants are supposed to prevent rusting, corrosion, freezing, etc).... bad #4. The general consensus is 50 - 50 mix. So how many litres you empty out from your radiator and block, divide it by two then pour in the amount of coolant and top it off with distilled water. Or you go buy those premixed coolants out there and just pour in neat, not mixed since it's already mixed. [/QUOTE]
