hi all
i am getting a used 2006 Honda Civic, about 41k miles (I know that's quite a bit). The car has clean CarFax history, and was acquired by the used car dealer directly from Honda Motors and was previouly used in their leasing fleet.

i took the car to a car shop to have it checked up; everything was fine except for a hissing noise that's coming out around the compressor area. The mechanic initially thought it could be a freon leak; but after diagnosing, it was not. The noise goes away after the car shuts down for about 20 minute. Is this normal? or should I worry about potential problems developing down the road?

Thanks much for any information you could share!

the sound is for 20 minutes?

maybe a bad seal ? run the system on max a/c and check the lines while running

 

It's the Evaporative system purging. If you have the car up in the air (IE changing your oil on a lift) it actually sounds like it's coming out of the oil pan.

Nothing is wrong with your car.

 

Mine does the same thing for a few minutes on a hot day with the AC running

 

mine too...and been since day one...no problems so far.

 

Same here on my LX although not as long as 20 minutes.
