Yesterday, I was waiting inline at a fast food drive-thru and noticed that my A/C was not cooling (it was 100 deg outside). I then put the car in park and revved up the engine and then cool air started to come out of my A/C vents. I did that for 2-3 mins, then noticed that my temperature gauge rose almost all the way to the top (it went right under the red). At that point I took off (out of the drive thru), to get some air flowing into the radiator. Sure enough it temperature doped fast. After looking under the hood. I noticed that one of the two fans to the radiator will not turn on. I’m guessing that’s what caused the over heating. I am not sure if I did any damage to the engine though, it did run really hot but not to the red mark but a hair line right under it. ---

I’m sure the engine is OK. The should come on when the AC is turned on. Could be bad fan or pwr to the fan. I do not know the year of the car, so it’s hard to be specific. ---

Hot day, waiting in the drive-thru with the A/C on, yes, both fans should be running. The one fan is not enough to keep the coolant cool under those conditions. But, I doubt you did any damage to the engine. It sounds like you caught it in time. ---

As long as it did not boil over, no damage was done…Fix the inoperative fan or sooner or later, damage WILL be done… ---

Check your coolant level . . . make certain that the engine is COLD and turned OFF when you do this. Do you know enough about cars to check the fan that wasn’t running? Rocketman ---

Thanks guys for your info on my 2001Galant. Yes Rocketman, my coolant levels are topped off and just changed out this year. I did take my car in for a oil change today, they said that the A/C fan is the one that is out. That is why my A/C stopped cooling when I was idling in the drive-thru. And it overheated when I revving up the engine.
