I am going to flush out my system and got some radiator super cleaner. I know that you are to drain and fill with super cleaner than top off with distilled water, run it for some time, than drain and fill with just distilled water to make sure all the radiator cleaner is out of the system than drain. But my question is that since I am sticking with the Toyota Super Long Life pink stuff, on the bottle it says to not add any water, so that little distilled water that will still be in the system(in the engine that cant fully get drained) hurt or ruin the new stuff or will I be safe?

The only reason why Im flushing the system is because I just hit 100,000 miles.

 

you should be fine, little distill water won't harm anything. i just flush my 100k mile tc. and the old coolant was clean, not rust at all.
