What coolent is good and what skoda recommends for the car skoda superb v6 vrs petrol 2.8L 2007 model, India location Hyderabad. Do I have to mix water or any other chemicals with coolent and pour it in coolent tank. How do I do this in the above mentioned model car. Please need immediate suggestions and information.  Where do I get this coolent. 

You probably have G12++. You can top-up with G12++, G13 or G12 evo. Given G12 evo is the latest, I'd suggest that.

 

If you get pre-mixed coolant, you can add it directly to the tank.

If you get concentrated, it'll need to be mixed with distilled water to the correct ratio.

 

Any VAG dealer should stock it (Audi, Seat, Skoda, Volkswagen)
