After replacing and/or inspecting every part of the cooling system on my '60 tbird except the radiator, I've determined that Murphy strikes again. The radiator must be clogged. With a new 160 degree therm. in, the car overheats within 15 min. of idling. When I touch the fins after this, the whole area is hot except for one spot on the lower left side. That spot is totally cold. Any shadetree fixes out there? I flushed the system already. A reman. radiator runs 300 bucks and I'm trying to avoid the expense right now.
