    Rad leak at transmission cooler fittings - suggestions?

    My 90 has been leaking coolant - ONLY when cold - I was under looking at things and can see that the transmission cooler fittings - not the brass - but the largest 'circle' which is a fitting in the brass tank (this is an original brass tank rad), seeps and you can see the liquid move/change when you shine a light on it and push on the line.
    I don't imagine that there is an IN CAR repair???? i have tried stop leak already without solution, possibly helped but not stopped.

    Crack like that might not be worth trying to repair, but you'd need it inspected off the car to know for sure. If it comes out and deemed repairable that would be a good time for a radiator shop to freshen it up too.

    Just be sure the cost doesn't exceed the price of new (aluminum?) radiator.
