What does the ac hose have to do with the red line? Do you mean the rpm gauge?

Alright with the engine idling with the ac on what are the high and low pressure readings?Also when you turn on the ac does the radiator fan come on?

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.
