S600 V12TT Intercooler Coolant??
Does anyone know what coolant fluid to use for the M275 V12TT intercooler circuit? When I looked, it seems to have a bluish tint to it (like watered down windex). I have an Johnson CM30 pump I wanted to install, but wasn't sure what fluid to use. Tips?
(on a side note, has anyone installed a second coolant pump in-line with the existing stock pump, but put it on an "always on" circuit so it's constantly circulating, rather than the stock "turns on only when it's hot"?)
Thanks!

Please be sure to have a detailed write up of the install. I hear that the stock pump last between 40-60 miles and robs you of at least 30hp? Not sure if this is true or not but I would love to see a full write up for us "Newb Members" to follow. thanks

Sounds like the new fluid from MB (which is blue in color, vs. the pale yellow of the old fluid). Same stuff that's in the rest of the cooling system...
