Hi, I recently bought a 1994 Audi 100 and discovered a coolant leak. I took it to the dealership and they said the radiator is leaking and that all these cars have leaky radiators. He recommended buying Stop Leak from a GM dealership. I went to one and all they had was something called Alumaseal. Is this safe to use in this car. Also, the Alumaseal says to put it directly into the radiator - but this isn't possible in this car, right?
Any help would be greatly appreciated!
Thanks!
