Well I changed the fluids today and found that it made a "little" difference. Around town after a half an hour or so she runs about 210-220, on the freeway after about 10 minutes she was down to 175-180. This tells me not enough air is getting through, but I am not sure what i can do about it. I have an electric fan on my radiator, how much of a temp difference would I see if I add a shroud? Because I live in the DC area I need to be able to sit in a 30-45min traffic jam without overheating, any ideas?

Thanks in advance,

Lincoln
