removed radiator
 

So heres the deal. I am replacing the core support for my 1.8T and i had to remove the radiator. Theres two lines running to the passenger side of the radiator that to me look like transmission fluid. Whats done is done but what i need to know is how i need to replace the fluid that i lost. It was not alot, just however much was in the radiator. And what specific fluid am i going to need. Thanks.

It's your ac lines I'm assuming. Might need a recharge now.

It's the automatic transmission fluid (the automatic transmission cooler is built in the radiator). Replace it with automatic transmission fluid if it's really temporary, but if not you should use the VW/Audi Automatic transmission fluid because these transmissions (auto) are very picky..

Do you think I could put it in the top of the radiator when I get things put back together or would I have to do the long process of lifting the car and adding till it spews out?
