A/C was running warm tried to recharge it, but that did not work. Within an hour of doing this the car's temperature ran hot. It's been 100 degrees in Atlanta all week plus I drive a lot of miles daily. I opened the hood and noticed the coolant reservoir was empty, so I filled it with coolant. After the car cooled down by letting it sit for approximately 1 hour. Now the A/C blows cold, but the temperature is still running hot. See no coolant leaks, fan runs, not leak on ground or on engine. The radiator was full of coolant and the reservoir stayed full. The heater runs hot and will quickly return temperature to normal. Could I have trapped air in the radiator or a clogged hose? Could it be thermostat or faulty temperature gauge? Should I run any system cleaner through the radiator?
