I'm trying to figure out what is going on with my cooling system. It's fine without the a/c running but once I turn the a/c on it starts to creep up on me. If I go on a 45+ min drive around town stop and go traffic while I'm sitting the temp on my car will start to rise. It gets to the point to were it starts going past 210* and I have my high speed fan to come on at 195* so I'm sitting there with my high speed fan on all the time and it seems like it's draining my bat after a while. I have a fluidyne rad and a new cap, high speed to come on at 195*, new water pump. Could the 10 year old evaporator coil just be old and restricted or is their something else I should look for?
