It would really help to know the high and low pressure readings?Also if there is plenty of air being pulled thru the radiator?Iam not there to see the readings so iam flying blind without the info.The number one thing i have seen cause a pressure issue on those cars are the expansion valves.

I need the pressures for starters as far as the fan goes make sure there is a good amount of air blowing out of it.
