So, you may remember from chemistry that water has the highest specific heat of any liquid due to its hydrogen bonds. You don't need a perfect antifreeze water mixture. In addition to changing the boiling and freezing points of the coolant, antifreeze contains cleaning agents to keep your system from clogging up. So, an incorrect mixture will not be your problem. Also, if the vehicle overheats at slower speeds but does fine when going faster, then it's most likely your fan. It could also be your water pump ( which he didn't mention). If the water pump is going bad, it may or may not leak or make noise. I had one seize, and my first warning was the belt slipping and making a lot of noise just before it snapped. The big takeaway here is that it most of these parts are cheap. If you do the work yourself, it could be as cheap as $14 and 30 minutes of work.

"Coolant is more effective at removing heat from an engine than water is"... That's 100% incorrect.
