The mystery coolant leak in my 95 960 sedan has reappeared. A month or so ago I had the heater core hoses replaced with new, clamps and all. The leak appeared to stop, but has now resumed. I put in about a litre of 50/50 a month right now, in what is supposed to be a sealed system.
I can smell the coolant after a long drive, but there is nothinng under the car. Plus the oil is find - it is not cloudy so I do not believe it is a head gasket leak.
The rad is 10 years old, but the upper and lower rad hoses and clamps were replaced with new about a year ago. I put a piece paper around the upper rad neck, seemed fine, no stains.
Ideas here appreciated. I hope to go on a ski trip in a couple of weeks and don't want to be stranded. Thx
