Humpback Whale in my hood?


I have a 2005 Honda CRV. Sometimes (not often) it will make a sound like the singing of a humpback whale. The sound will continue even after I turn the car off, for a few minutes. It doesn’t seem to matter if the air conditioner is on or not. What could be causing this?


You first. Lift the hood and try to determine which component is making the noise. If you can’t identify any of those “dark, greasy shapes,” maybe you have a neighbor who can.


Ditto to what Steve said.

Since it still continues for a few minutes after the car is turned off, don;t forget to look at the cooling fan. Other likely components, the PS pump, the alternator, the AC compressor, etc. shut down immediately with the engine, but the cooling fan is run for a minute to clear out heat from under the hood.


Thanks! I just assumed all the fans stopped when the car was turned off. I will check it out!
