I have a '62 3000 tri carb BT7 which had an overheating issue last summer. The air temperature was 32C or 90F and the radiator temp at a highway speed of 65 started climbing towards 200F. Once in town the temperature came back to 190. The car has a new 160F thermostat and I just had the radiator checked and flushed with nothing found. At cooler outside air temperatures, the radiator temperature seldom exceeds 180F. I found an old thread on this forum which talked about the installation of an air deflector assembly which is completely missing on my car and I am wondering if this is the source of my heating problem. The first question is "do I need the air deflector assembly?" and the second is "how difficult is it to install?" The pictures on that early thread show the attachment at the top but the bottom is a bit vague. It appears to attach to a support bracket for the grill but there is little room back there especially once that deflector panel is in place. Also I have the radiator out at the moment which would aid the installation of the air deflector but that would make installing the radiator more difficult. Which should come first. Any and all tips appreciated
