when i turn on my ac the temperature gage rises to red zone when i turn it off the tenperature gage goes back to normal. can anyone tell me what this could possibly be?
1) low coolant 2) added load of A/C compressor running 3) fan not coming on 4) thermostat in engine 5) water pump failing 6) something blocking radiator (that one's a long shot)
