    You're in the wrong forum. You need to be in the Seville section for old sidewinders. This forum is for newer AWD/RWD STSs.

    Generically speaking you still may have a pin-hole leak (that doesn't show as a puddle), however, if this were the case you would still have that hot sweet smell of antifreeze being 'steamed off'.

    Even though this is the wrong forum it sounds like the infamous headgasket leak to me.

    The HG repair is expensive but if the car is otherwise good condition, many members find it worthwhile. They are beautiful and great driving cars.
