Replaced the coolant sensor but forgot to tighten the filler cap before I pulled the sensor and lost a lot of antifreeze, including draining the reservoir. No VW/Audi dealers open today. Local parts shop says Preston's orange color is equivalent but I also see that Prestone makes a pre-mixed clear product that claims is good for ANY make and model car. The alternative is to refill with water and then drain and refill tomorrow when I can get to Audi/VW product. Advice please!

then drain and refill with proper mixture tomorrow. it will be impossible to get all the orange stuff out and your coolant won't be pink anymore.

Is the Audi/VW stuff THAT special or is it just the color?

Vegas-roadster

Red in color.

Web search indicates Pentosin is a supplier of G12 to Audi

Vegas-roadster

Pentosin G12 is listed on several audi/VW performance parts sites. Bracketracer gives it a thumbs up too.

I repeat... fill with distilled water. Then drain some out tomorrow, and pour in some G12. If you keep track of how much you're adding / removing, you can do some simple calculations to return it to an approximate 50/50 mix.

Carry on this conversation without me....:-)

What exactly is the measurements on the mixture in litres not 50/50 to 70/30?

In otherwords, how much coolant and water does our TTs take?
