Car overheated yesterday, or at least the red light came on that said it was about to overheat. I pulled over, let it sit a few minutes - no more than 5, started it up again and it was fine. It did not reheat again while out earlier in the day. Got out in the evrening to drive it, it did the same thing while waiting in line at a drive thru, I revved it, and it cooled down, and stayed cool the rest of the evening. This morning, same thing again. Started to over heat, I turned it off before it got the red, waited - and now it doesn't overheat. Had mechanic check fluid levels in radiator while getting oil changed yesterday and he said levels are fine. He said perhaps the thermostat was stuck and granted I know very little about vehicles - the thermostat seems to be working fine. I'm wondering more about a fan, secondary fan or perhaps a fuse.

I also have no problem donating, but am on a fixed disability income and would prefer to give after I know the expertise of the situation. I've been taken by some of these sites too many times.

Can you tell me the actual temp in degrees F? Is the radiator fan running when it gets hot? Check the coolant temp sensor--water pump--clogged radiator or coolant passages. Is your serpentine belt in good shape? It's always good to check the thermostat.

I think anybody here will talk to you, donation or not. If anybody else has any ideas, please jump in, no problem.

It seems the most common, over heating at idle, not enough tension on the drive belt. Any applicable trouble codes, relating to problem? Some of the national brand autostores will check codes, for free. Other wise you need an obd2 code reader, at least, to check codes.

I do not know the actual temp when it got hot other thanthe gauge was in the red, and the light was on in the dash. As far as the radiator fan, I will check that next time. I'm just so afraid of causing more damage that my first reaction when I see it getting hot is to turn it off. Serpentine belt was replace last January but I'll have that checked as well. Open to any and all suggestions. Thank you.

I agree with you, if it is truly overheating, kill the engine. If possible don't drive it till you fix it. I haven't seen any feedback from you on my suggestions? I can only make suggestions on what to check. You have to do the testing.
