But remember not to keep just distilled water in your system for any long period of time because you will suffer impeller erosion, which is prevented by the lubricants in antifreeze.

But, to get back to my original premise, given what I've been reading, I believe that when a lot of SRT owners change their cooling fluid they are only draining the engine cooling side (8.1 quarts in my case) and not the intercooler cooling side, unless they drop or remove the charge cooler radiator and drain it as part of their procedure.
