renzr55 Posted November 6, 2020 Share Posted November 6, 2020 Hello all, I am new to the forum and would like to apologize if this issue has been posted somewhere else. If it has, please point me in the right direction. Over the last few weeks, my 2009 Fusion started to make a squealing noise that I have not heard before. It is totally strange. Sometimes it makes it when driving, sometimes when the engine is idling, and sometimes it makes the same noise a few minutes after the car has been turned off. The car drives well, with no performance issues of any kind, no lights showing on my dashboard. This is driving me nuts. So please, if this is a known issue, give me a clue as to what to look for and start troubleshooting. Thanks in advance. 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted November 7, 2020 Share Posted November 7, 2020 (edited) Your post has been moved to another section of the forum. Site Feedback & Help is intended for questions and comments about the operation of the website itself. Questions and comments about the Fusion should be posted in an appropriate section. WRT your issue, first, outside of the model year, you furnished no details about your car, i.e., engine, transmission, FWD/AWD, accumulated mileage, etc. Next, it's difficult, at best to diagnose noises over the Internet. Which part of the car is it coming from? Front, rear? A video might help. The usual suspects for squealing noises seem to be ruled out by the fact that the noise sometimes continues after the car is shut off. In light of that, I'd hazard a guess that it could be a cooling fan but I emphasize that it's a guess.

renzr55 Posted November 7, 2020 Author Share Posted November 7, 2020 (edited) Thanks for the insights. Here is more information. Sel, v6, 110k, no idea about the transmission (the one that comes from factory), fwd. It is hard to determine where the sound is coming. I'm either inside or walking away from it. I've found myself patiently waiting with open hood, but never happens. It is loud and sounds like a coyote hawl.

renzr55 Posted November 10, 2020 Author Share Posted November 10, 2020 Just a couple of days ago, the car made the same noise a good few minutes after the car engine was turned off. Definitely, no cooling fan was turning since it only a few seconds for the fan to come to a complete stop. So please, if anyone had a similar issue, point me in the right direction. Thank you. 0 Quote Link to comment Share on other sites More sharing options...

Were you observing the fan or just assuming it should have been stopped? 0 Quote Link to comment Share on other sites More sharing options...
renzr55 Posted November 11, 2020 Author Share Posted November 11, 2020 If is not the fan. No fan keeps turning after 4 minutes of the car being turned off. Besides, I measured ho long the fan kept turning after the engine off, x-bar = 17.33 seconds. If there is a clue, anything at all that is not the cooling fan, please let me know. 0 Quote Link to comment Share on other sites More sharing options...
eGuru Posted November 11, 2020 Share Posted November 11, 2020 (edited) If you weren't observing the fan, how are you eliminating it is a cause of the noise? Edited November 11, 2020 by eGuru 0 Quote Link to comment Share on other sites More sharing options...

You are wrong about my profession - I am not a mechanic. But you are correct that I was not so bright when I tried to help you. Clearly you are much more highly educated than myself or the average forum member. Strange that you would take the time to observe the turn-off time so many times that you could determine a mean (x-bar) of the fan turn-off time to 2 decimal places but can't be bothered to open the hood when your sound issue occurs to check if your sound issue might be due to the fan. Please tell us how you were able to determine "no fan keeps turning 4 minutes of the car being turned off." because I am curious how a defective fan speed controller or CHT sensor couldn't possibly cause the fan to startup again after the engine has been turned off. Awaiting some enlightenment sir. 0 Quote Link to comment Share on other sites More sharing options...
