Coolant - G12 ONLY or with water???

[audi18tdan]

what do you all reccomend, straight G12 coolant or G12 mixed with say 50% water?

I am wondering this as my Fan seems to come on alot these days and am wondering if i would get better cooling if i include water.

should be mixed in accordance with the bottle i think its 50/50 or so.

More importantly find out where its going check the water pump as it can leak through the bearing as it deteriates which will then blow you water pump eventually
