So you stated that you added water. and then more water. If you only added water, it will boil over. You need a 50/50 coolant mixture.

So I read the entire Rick article. Interesting. And then at the end of the article, he has this last paragraph. So this guy can't make us his mind that water is OK to use or it's not. Self-proclaimed expert that waffles. In the real world, I have experienced water only as boiling out and when a 50/50 coolant/water mixure is replaced, all is better. So I ask, what say you?

I've run straight water many times and the vehicle didn't overheat. I'd like to know what that last picture is supposed to signify, with regards to the OP about overheating.

When you start it up cold just leave the cap off (or maybe you are) but if your getting exhaust gas into the cooling system you should be getting a lot of air bubbles surfacing. If no air bubbles make sure you can see the coolant moving in the radiator once the thermostat opens. That will tell you if the water pump is actually moving water.
