2.4 V6

I got my aircon fixed yesterday but after i got my car back the coolant light came on when i was driving home. When I checked the coolant container was empty. I toped it off with water already but do i need to add coolant to maintain the concentration?

(I already checked there is no leak the idiots just forgot to replace the coolant when finished fixing the aircon.)

they should be half and half.. but water is the cooling agent

Don't forget to get the proper coolant for your car, and use distilled water.

What happens if you mix green Prestone-type stuff with the the Audi coolant?

and put the pink/red stuff in.

... but when you drive the level drops. Add water (distilled) and you should be fine... As long as you have enough coolant in the container, you can add in the mix -- it does not really have to be 50/50 or anything close to that...

um.. i dident have any distilled water around so i used tap water...

remember the white stuffs left on the pot after you boil water? calicium deposits, probably not the best thing to trap inside the radiator.

now, it's not good for it, will it cause any malfunction.. maybe.. the perfect solution would be to do a radiator flush, but if it's too much trouble, don't worry about it cuz it shouldn't be that big of a problem
