What is this noise? A/C related?

[KITTinKC]

Hello, everyone -

I've been having this problem for the last few weeks with my 2010 Explorer. It almost sounds like a jet engine at times. I did have the A/C recharged at Ford about 3 weeks ago, and this noise started right after that.....but I still don't know for sure if it's related. It's at its worst in hot weather, maybe 90 degrees or hotter. It happens when I accelerate right after start up & the engine is already warm (for example, if I run into the grocery store). It happens for about a minute then goes back to normal. The RPM's are a little high when this is happening as well. In this video, it's really noticeable around the 23-second mark. At about the 45-second mark, it has gone away. I had to trim out the first 15 seconds of this video which all it was was me backing out of my driveway.

I have it at Ford, and I'm getting the usual "we can't get it to reproduce the noise" jargon. I even let them listen to the video this morning and the lady that checked the vehicle in definitely noticed it then......and I can get it to reproduce the noise any time the weather is hot. Anyway, that's a whole different issue. Any help on this would be greatly appreciated!

Sounds like the infamous cooling fan problem! look into replacing it!

Thanks!

Any recommendations on what I can tell Ford to look for besides asking them to take a ride with me? They're claiming it just isn't acting up at all for them......but it still makes this noise for me every time!

1. They're not being honest with you. They know exactly what that noise is. Is this dealership where you bought the truck? Is there a current warranty?

2. Mine does the same thing, only during the first minute of driving. I don't consider it an issue. My temp has never oscillated.

Thanks for the reply!

Yes, it's covered by a Ford extended warranty. And I purchased the Explorer from a different Ford dealer.
