General   (General discussion, talk about anything.)

As much as I appreciate the schoolboy lessons in how an engine works you are still not really answering my questions

A quick google tells me this......

The boiling point of a 50/50 mix of distilled water and ethylene glycol, (the main constitute of common or garden antifreeze) has a boiling point of 106 degC

The same google tells me the boiling point of VWs G13 coolant is actually 175 degC

So my question to you now is......are certain VW engines designed for use with G13 coolant likely to see coolant temperatures above 106 degC in use and if they do see such temperatures what would happen if you don't use their recommend coolant and instead use one one with a boiling point about 70 degC lower?
