Just wanting to know anything I may be missing since my car has been running to hot. without ac running driving around the car runs around the M and A on the normal part of the temp gauge and when the ac is on it will go past the L and almost boil. I have run water through the motor and the radiator, put a 180 thermostat, replaced the waterpump with a ford racing aluminum piece, checked the timing and put it at 13-14 degrees and fixed the connector switch that connects to the fan since one of the connectors was melted. The fan kicks on when the temp gets between the M and the A on the temp gauge and the higher spped kicks on when its even hotter which to me seems a little to late. Do I need to replace the temp sensor that tells the fan when to kick on? Im thinking that next time im home(in 3 months) I need to get a fluidyne aluminum radiator but if anyone could give me an idea of how to check if the radiator is bad cause it seems to flow water from what I can tell and the thermostat is brand new and works. Any help would be great
