Can damage be done by running 100% G12 coolant instead of a mix

Ran mine like that for quite some time after a shop worked on the car.
Find some way to drain the system a little and top it back off. Either siphon/pump it out of the reservior, unhook a hose or pull a coolant sensor.
If you really want to do it, pull the lower radiator hose, let it drain, and start filling back up with a 50/50 mix. You'll still have more coolant than water, but it'll be a lot closer.
Should be a chart on the side of the bottle showing different mixes and the freeze temps, quite a wide range of OK mixes.

Granted you'll probably never see the temp pure G12 freezes at unless you live in canada ![Smile](https://www.audiworld.com/forums/images/smilies/smile.gif)
Couldn't find a handy chart for G12, but normal antifreeze at 100% freezes at -13C, same antifreeze with a 70%af/30%w mix freezes at -64C
If you never see freezing temps, best combo for heat transfer capability is distilled water + water wetter

and i have changed my switch twice to make sure that isnt the factor, but i bet my coolant never reaches "noraml temp" and my gauge always reads a little below center...im running 100% g12 btw....ouch
