When i check the radiator to make sure le prestone level was alright the where dropplets of oil in it. But il checked the oil level and it was all right.What do i have to check?I have diesel golf 92 with 278,291 KM
Steve anyway to clean it. I don't have a radiator cap, i fill the radiator trought the overflow. Would it be a good idea to do a radiator flush.
