guys, so the overheating problem has fudged my brain too many times now. After about 1 hour of driving, I have to add some more water in the system. Right now I'm running it on 100 % distilled water. I was wondering can I put 100% antifreeze in, what affect would this have, also does anyone else run their machine on water alone without antifreeze, maybe that's the reason it's overheating this time. I also has to be noted that it is THE hottest summer ever where I live with temperatures up there around 40-41 degrees Celsius, which is 105 degrees Fahrenheit.
